Low-temperature damage is one of the key factors that limits the distribution of tree species in an area. This damage in not always the result of low temperatures in winter or during bloom. Actively growing trees or parts of trees do not harden, may be injured by lower temperatures or erratic temperature fluctuations in autumn. It is essential, therefore, that the capability of each separate scion/rootstock combination to tolerate cold temperatures should be tested especially when the trees are young and a serious climate change is taking place. The overall goal of this study was to investigate the effect of early autumn temperature on fruit and grapevine species, included various cultivars and rootstocks, after plantings and to determine the cold hardiness. The autumn term of 2022 was one of the periods we have experienced notable temperature fluctuations, particularly in September. The day-night temperature difference reached 21.5 degrees on September 24. Subsequent field observations revealed significant variation in autumn cold tolerance among species, cultivars, and rootstocks. In this study, cold injury was observed in fifteen of the 29 examined species in the autumn after planting. During unfavorable autumn conditions, young trees of fig, persimmon, walnut, and chestnut cultivars were classified as very susceptible. It is most likely that the hardening process in these four species was more affected by erratic temperature fluctuations in the early phase of hardening.

Hesperis isatidea (Boiss.) D.A.German & Al-Shehbaz, a member of the Brassicaceae family, represents a distinctive natural species characterized by its fragrant, conspicuous inflorescences, unique flower coloration, and distinct feather-like foliage. The Turkish name of the species is known as “Allı Gelin”. This species is native, exhibiting resilience to drought conditions and requiring minimal care. Cultivation studies on this species were carried out at Erzincan Horticulture Research Institute (Turkey) with project number 106G022 within the scope of TÜBİTAK (Turkish Scientific and Technological Research Council). The research aimed to determine optimal production techniques through generative and vegetative propagation methods. The project, initiated in 2013 and concluded in 2022, focused on developing a cultivar of the Allı Gelin plant using texel selection breeding techniques. Thirteen populations of Allı Gelin from institute's gene pool were utilized. Employing the Texel Selection method, four distinct lines were identified: compact, tightly spread compact, pyramid1and pyramid-2 shaped. Subsequent baby plant tests revealed stability in the tightly spread compact and pyramid-1 lines, leading to their selection for further breeding. Although breeding efforts continued on the compact line, the pyramid-2 line was discontinued due to an inability to attain the desired stability. The successfully tested variants, namely the pyramid-1 and tightly spread compact forms, have been earmarked as candidates for outdoor ornamental plant varieties. Registration procedures for these candidates are underway. These new varieties promise to enrich diversity within the ornamental plants sector, potentially enhancing competitiveness in foreign markets.

Pitaya, Hylocereus spp. (Caryophyllales: Cactaceae) has been one of the new species cultivated in Türkiye for recent years. There are many limiting factors, including pests, diseases and weeds, to decrease the yield and fruit quality in pitaya (dragon fruit) areas in Türkiye. In addition, the pests of pitaya is not fully studied therefore this study has been conducted to determine mealybug species in pitaya greenhouses in Türkiye. The present study was aimed to determine mealybug species and its natural enemies (parasitoids, and predator insects) in pitaya greenhouses in Adana, Mersin, and Antalya between 2021 and 2022. According to results of this study, 2 different mealybug species was determined; Phenacoccus solenopsis Tinsley 1898, Phenacoccus madeirensis Green, 1923 (Hemiptera: Pseudococcidae) in pitaya greenhouses. Moreover 1 parasitoid (Aenasius arizonensis Girault (Hymenoptera: Encyrtidae), and 2 different predatory insects from 2 different order and 2 different families (Chrysoperla carnea Stephens (Neuroptera: Chrysopidae), Nephus includens Kirsch (Coleoptera: Coccinellidae)) were detected within this study. As can be seen above results, these two invasive mealybug species have wide spectrum host plants and may cause economically important damages on pitaya, if natural enemies cannot work successfully or control strategies do not applied properly in pitaya greenhouses.

The main objective of the research was to assess weight loss, respiration rate, firmness, soluble solids content (SSC), titratable acidity and vitamin C content of the autochthonous Karasüt apple throughout cold storage. The ‘Granny Smith’ cultivar was used as positive control. The fruit were kept at 0.0±0.5°C and 90±5% relative humidity. Quality losses were observed in the apples during cold storage. The weight loss of Karasüt apple (6.70%) was higher than that of Granny Smith (2.20%) at the end of cold storage. A lower respiration rate was measured in the Karasüt apple (1.23 nmol CO2 kg-1 s-1) at harvest compared to the positive control (1.53 nmol CO2 kg-1 s-1) at harvest. On the contrary, the respiration rate was higher on days 30 and 60. The fruit firmness of Granny Smith (27.14 N) was higher than that of Karasüt (22.47 N) at the end of cold storage. During the cold storage, a higher SSC was obtained from Karasüt apple compared to the positive control. However, titratable acidity was lower in Karasüt apple. In the first two measurements of cold storage, the vitamin C of Karasüt apple was higher than that of the positive control. As a result, it was revealed that Karasüt apple occurred faster quality losses during cold storage than Granny Smith apple fruit.
研究的主要目的是评估自产卡拉苏特苹果在整个冷藏过程中的重量损失、呼吸速率、坚实度、可溶性固形物含量（SSC）、可滴定酸度和维生素 C 含量。Granny Smith "品种作为阳性对照。果实的保存温度为 0.0±0.5°C，相对湿度为 90±5%。在冷藏期间观察到苹果的质量下降。在冷藏结束时，Karasüt 苹果的重量损失（6.70%）高于 Granny Smith 苹果（2.20%）。与阳性对照（1.53 nmol CO2 kg-1 s-1）相比，卡拉苏特苹果在收获时的呼吸速率较低（1.23 nmol CO2 kg-1 s-1）。相反，第 30 天和第 60 天的呼吸速率较高。在冷藏结束时，Granny Smith（27.14 N）的果实坚硬度高于 Karasüt（22.47 N）。在冷藏期间，卡拉苏特苹果的 SSC 值高于阳性对照。不过，卡拉苏特苹果的可滴定酸度较低。在冷藏的前两次测量中，卡拉苏特苹果的维生素 C 含量高于阳性对照。结果表明，与 Granny Smith 苹果相比，卡拉苏特苹果在冷藏期间的质量损失更快。

This study aimed to investigate the effects of a liquid fraction of digestate obtained from different biogas plants on the growth and mineral nutrition of cucumber plants under greenhouse conditions. For this purpose, Liquid Biogas Digestates (LBD) obtained from two different plants (A-B) with different properties were applied to pots with 10 kg of soil in 5 different doses (0, 20, 40, 60, and 80 t ha-1) and the effects of the treatments were observed. As a result of the research, the highest yields increased 24.6% for digestate A in A5 (80 t ha-1) and 29% for digestate B in B3 (40 t ha-1) compared to control. While LBD contributed to the increase of N, Ca, Zn, Cu, and Mn concentrations in the leaf samples, it was observed that the dose increase did not have a linear effect on N, Ca, Zn, Cu, and Mn concentrations in the leaf samples. It is thought that liquid biogas wastes produced in biogas plants have positive effects on fruit yield, agricultural practices can be taken the basis in the disposal of these wastes and the use of liquid biogas residues in soils by eliminating potential risks can provide significant benefits.
本研究旨在探讨从不同沼气厂获得的沼液对温室条件下黄瓜植株的生长和矿物质营养的影响。为此，将从两种不同植物（A-B）中获得的不同性质的液态沼气沼渣（LBD）以 5 种不同的剂量（0、20、40、60 和 80 吨/公顷-1）施用到装有 10 公斤土壤的花盆中，并观察处理的效果。研究结果表明，与对照组相比，A5（80 吨/公顷-1）中的沼渣 A 产量增加了 24.6%，B3（40 吨/公顷-1）中的沼渣 B 产量增加了 29%。虽然枸杞多糖有助于增加叶片样本中的氮、钙、锌、铜和锰浓度，但观察到剂量的增加对叶片样本中的氮、钙、锌、铜和锰浓度没有线性影响。人们认为，沼气厂产生的液态沼气废料对水果产量有积极影响，农业实践可以作为处理这些废料的基础，在土壤中使用液态沼气残留物可以消除潜在风险，从而带来显著效益。

Within the scope of the study, the effect of hydro-distillation times on Citrus sinensis (Navelina) fresh peel essential oil composition was investigated. For this purpose, five different distillation times (10, 15, 30, 60, and 120 min.) were evaluated. Research findings showed that the distillation time was not effective on the orange essential oil composition. It was determined that the most important components of C.sinensis peel essential oil were limonene (96.52-96.61%) and myrcene (2.03-2.06%). In addition, hydrodistillation (HD) and cold press (CP) essential oils were compared in terms of yield and some physical and chemical properties. In terms of oil yield and optical activity, the values of the oil obtained by hydrodistillation method were higher than those obtained by cold press, and the refractive index and density values were found to be lower. In terms of component ratios, it was seen that there was no significant difference between the two methods.

This study aimed to determine phenotypic diversity in the germplasm collection of Solanum aethiopicum, also known as scarlet eggplant, under Mediterranean conditions. Two different experiments were established in which morphological and valuable agronomic traits were employed to measure diversity among 57 and 55 accessions, respectively. The experiments were carried out in a greenhouse and open field, and descriptors designated by the European Cooperative Program for Plant Genetic Resources (ECPGR) and the International Board for Plant Genetic Resources (IBPGR) were used to measure the plants and fruits. The results from descriptive statistics on quantitative traits data of plants and fruits show a great variation among accessions of Solanum aethiopicum. Multiple correlation analysis in the two distinct experiments shows that the highly correlated variables/descriptors represented fruit quantitative traits. Finally, results from principal component analysis (PCA) confirm that the overall differences observed in the germplasm collection of Solanum aethiopicum were mainly due to fruit quantitative traits, which are decisive for phenotypic characterization of this eggplant.

This research was conducted to test the effect of oxygen content (low O2, high O2, air) during hermetic seed storage at 20±2°C over 8 and 12 months on seed germination and seedling root and shoot length in tomato, onion, cabbage, and marrow seeds. Samples with low oxygen storage had higher seed germination as well as longer root and shoot lengths than both control and high oxygen storage. When the storage period extended from eight to 12 months, the germination percentages also reduced. However, these results varied among the species. The greatest advantage of low oxygen storage was obtained in tomatoes, which exhibited 15% and 9% higher germination compared to the control after eight and 12 months of storage, respectively. The longest root and shoot lengths of 6.4 cm and 11.6 cm, respectively, were obtained from the low oxygen storage treatments. A similar positive effect of low oxygen storage was observed in onion and cabbage seeds but not in marrows. Results indicated that oxygen level in the packets during storage can be an effective component to maintain high seed germination and seedling growth potential (seed vigour). The difference in the effect on different species is a matter of further research.

The effect of different planting depths on emergence characteristics was investigated in the study carried out using seeds of Marigold (Tagetes patula) collected from nature. In addition, the most effective dose that can be used in priming treatments was tried to be determined by examining the effects of moringa leaf extract treatments applied at different doses in terms of emergence rate, emergence time, survival seedling rate, true leaf emergence time, emergence speed index, coefficient of velocity of emergence and vigor index values. After the T test, it was determined that different planting depth treatments created statistically significant differences especially in the survival seedling rate. It has been observed that the fact that the planting is exposed causes an increase in the survival seedlings rate. In addition, after hydropriming and moringa treatments, the highest seedling emergence rate in both planting depths was obtained from hidropriming and moringa leaf extract (4 g L-1) treatments, while moringa leaf extract (8 g L-1) treatments was the treatments group that provided the earliest emergence compared to other treatments. All treatments groups were statistically different compared to the control group in terms of emergence speed index, coefficient of velocity of emergence and vigor index values in both planting depths, and HP and M3 treatments were the treatments groups that gave the best results. As a result of the study, it has been determined that surface sowing can be recommended in marigold cultivation and moringa treatments improve the emergence characteristics.
这项研究利用从自然界采集的万寿菊种子，调查了不同种植深度对出苗特性的影响。此外，还通过研究不同剂量的辣木叶提取物处理对出苗率、出苗时间、成活率、真叶出苗时间、出苗速度指数、出苗速度系数和活力指数值的影响，尝试确定可用于起苗处理的最有效剂量。经过 T 检验，可以确定不同种植深度处理的差异具有统计学意义，尤其是在成活率方面。据观察，裸露种植会提高幼苗成活率。此外，在水刺和辣木处理后，两种种植深度的出苗率最高的是水刺和辣木叶提取物（4 克/升）处理，而辣木叶提取物（8 克/升）处理是与其他处理相比出苗最早的处理组。与对照组相比，所有处理组在两个种植深度的出苗速度指数、出苗速度系数和活力指数值方面都存在统计学差异，其中 HP 和 M3 处理组的效果最好。研究结果表明，在万寿菊栽培中可建议进行表层播种，森草处理可改善出苗特性。

In addition, the most effective dose that can be used in priming treatments was tried to be determined by examining the effects of moringa leaf extract treatments applied at different doses in terms of emergence rate, emergence time, survival seedling rate, true leaf emergence time, emergence speed index, coefficient of velocity of emergence and vigor index values. After the T test, it was determined that different planting depth treatments created statistically significant differences especially in the survival seedling rate. It has been observed that the fact that the planting is exposed causes an increase in the survival seedlings rate. In addition, after hydropriming and moringa treatments, the highest seedling emergence rate in both planting depths was obtained from hidropriming and moringa leaf extract (4 g L-1) treatments, while moringa leaf extract (8 g L-1) treatments was the treatments group that provided the earliest emergence compared to other treatments. All treatments groups were statistically different compared to the control group in terms of emergence speed index, coefficient of velocity of emergence and vigor index values in both planting depths, and HP and M3 treatments were the treatments groups that gave the best results. As a result of the study, it has been determined that surface sowing can be recommended in marigold cultivation and moringa treatments improve the emergence characteristics.","PeriodicalId":13139,"journal":{"name":"Horticultural Studies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139269763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The study was conducted in İzmir, Manisa, Çanakkale, Balıkesir, and Bilecik provinces to determine nematode diversity and vineyard community structure. Thirty-six genera (İzmir 34 genera; Manisa 32 genera; Bilecik 21 genera; Çanakkale 28 genera) with different trophic groups were recorded: fungivores (3 genera; e.g., Aphelenchoides spp.), bacterivores (9 genera, e.g., Achromadora Cobb, 1913 and Plectus Bastian 1865 spp.), omnivore (4 genera; e.g., Aporcelaimus Thorne, 1936 and Dorylaimus Thorne & Swanger, 1936 and Eudorylaimus Andrassy, 1959 spp.), predators (3 genera; e.g., Clarkus spp.), herbivores (17 genera; e.g., Boleodorus tylactus Thorne, 1941). Twenty-six species of herbivores were identified, and the most common species were from the genera Filenchus Andrassy, 1954, Geocenamus Thorne & Malek, 1968; Pratylenchus Filipjev, 1934, and Helicotylenchus Steiner, 1945. Dorylaimus Dujardin, 1845; Mesorhabditis Osche, 1952; Cephalobus Bastian, 1865; Acrobeloides Cobb, 1924; Mesodorylaimus Andreassy, 1959; Aphelenchus Bastian, 1865, and Ditylenchus Filipjev were other commonly found nematode genera.
