In our study, three strawberry (<em>Fragaria x ananassa</em>) cultivars were subjected to nightly UVC treatment (20 s, 0.02 kJ/m²) delivered through LED technology (with a peak at 276 nm) within polytunnel conditions in Central Finland. The aim was to evaluate the effectiveness of the UVC treatment in inhibiting powdery mildew (caused by <em>Podosphaera</em> spp.), as well as to assess its impact on crop yield, fruit quality, firmness, volatile organic compound (VOC) profile, and leaf properties across two consecutive growing seasons. The UVC treatment successfully suppressed the growth of powdery mildew in all three tested strawberry cultivars throughout the experiment, without causing any visible damage to the leaves. The UVC treatment led to an increase in the crop yield of marketable fruits without affecting their size. The impact on fruit quality varied, depending on the specific cultivar, sampling time, and the year under consideration. Fruit firmness following 2–3 days of refrigeration improved due to the UVC treatment. Our findings suggest that UVC treatment can alter the fruit's VOC profile, either directly or indirectly through disease management, affecting its aroma. These findings emphasize the diverse advantages of UVC treatment in enhancing disease resistance and enhancing specific fruit attributes. This suggests the potential for integration of UVC treatment into plant production systems, particularly in tunnel cultivation within Nordic conditions, as a promising approach to improve overall crop management strategies.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142428737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the anisotropic nature of biological materials, the moisture content of tomato stems significantly impacts their physical properties. This study investigates the influence of varying moisture content on temperature and cutting force during the ultrasonic cutting of tomato stems. Initially, the moisture content of tomato stems at different maturity stages was measured using a water activity meter. Mechanical properties were characterized using a universal testing machine, and thermal properties were analyzed with a differential scanning calorimeter (DSC). Regression models were established to correlate moisture content with these material properties. Additionally, a three-dimensional microscopic model of stem skeletons, interfaces, and fiber bundles was created to simulate the fracture mechanisms during ultrasonic cutting under different moisture levels. Single-factor and response surface optimization experiments were conducted using a custom experimental setup under varying maturity stages, excitation frequencies, and voltage variations. Results showed that after 24 h, the peak temperatures for tomato stems at different maturity stages were 97.84 °C, 80.59 °C, and 74.15 °C, with corresponding cutting forces of 0.492 N, 0.544 N, and 0.998 N, respectively. The discrepancy between experimental results and simulation data was within 10 %. Higher moisture content was found to enhance the thermal conductivity of fiber materials, aiding in the fracture of fiber bundles, thus reducing cutting time and force.

This study explored the enhancement of phosphorus bioavailability through the co-pyrolysis of rice straw with magnesium oxide (MgO) at 800 °C, resulting in a novel biochar-based phosphate fertilizer, termed MRS8-P. The treatment involved enriching biochar with MgO to increase phosphorus loading and evaluating its effects on soil physicochemical properties and citrus seedling growth. Soil analysis revealed improved physicochemical properties, including increased available phosphorus (AP), enhanced soil pH, higher electrical conductivity (EC), and rapidly increased available potassium (RAK); however, a temporary immobilization of alkaline hydrolytic nitrogen (AHN) was noticed by biochar application. Notably, soil microbiota dynamics shifted with an increase in beneficial taxa, such as <em>Proteobacteria</em> and <em>Actinobacteria</em>, which enhanced phosphorus solubilization and organic matter decomposition, and a decrease in taxa, such as <em>Methylomirabilota</em> and <em>Desulfobacterota</em>. These microbial changes significantly contribute to soil fertility and nutrient availability. The application of MRS8-P significantly enhanced nitrogen, phosphorus, and potassium (NPK) uptake in citrus seedlings, as demonstrated by increased growth metrics, such as plant height, stem coarseness, and chlorophyll content measured by the SPAD index. These findings underscore the potential of MRS8-P in reducing reliance on traditional phosphate fertilizers, which are linked to environmental degradation through runoff and pollution.

The extent of genetic diversity in wild citron in relation to environmental variables has not been documented. In the present study, we analyzed genetic diversity and environmental association of wild populations of <em>C. medica</em> in northeast India using 15 polymorphic nuclear SSR (simple sequence repeat) markers and 21 environmental variables.

Apple trees that have been cultivated in the same location for decades are particularly vulnerable to these environmental changes. While most of the experiments on apple fruits under climate change have been conducted using potted trees in the short term or in small chambers, we designed field-based, long-term greenhouse experiments under controlled environments to assess potential future changes in the acceptable harvesting window and fruit quality. In 2015, apple saplings grafted on M.26 rootstock were planted to establish three mini-sized populations with two rows of eight trees, each including six ‘Tsugaru’ (early maturing) and six ‘Fuji’ (late maturing) cultivars. Subsequently, in 2018, they were enclosed in independent greenhouses to keep them under ambient temperature and CO₂ concentration (GH-A), 3 °C higher and ambient CO₂ (GH-T), or 3 °C higher and 200 ppm elevated CO₂ (GH-C) before sprouting to after harvesting from 2019 to 2022. Our 4-year investigation revealed that the optimum harvesting period for ‘Tsugaru’ in GH-T and GH-C is earlier in the calendar date as is the spring phenology, remained unchanged based on days after full bloom (DAFB) compared to GH-A. However, for ‘Fuji,’ the optimum harvesting period was judged to delay approximately 10 days in the calendar date owing to slow coloration and soluble solid accumulation, although it also experienced similar advancements in spring phenology. Additionally, it is anticipated that the acceptable harvesting window will become narrow in the future owing to the rapid softening in firmness and decrease in acid concentration. Furthermore, high temperatures in GH-T tended to result in a decrease in fresh weight, firmness, acid concentration, starch rating, and color rating for both varieties compared to GH-A. In addition, for ‘Fuji,’ very few instances of watercore were observed. However, elevated CO₂ in GH-C tended to promote fresh weight for both varieties and increase the watercore appearance for ‘Fuji,’ mitigating the effects of high temperature. No other significant trends in the fruit quality indices were observed between GH-C and GH-T.
