One of the important reasons that environmental stresses such as drought reduce the growth and photosynthesis ability of the plant is a disturbance in the balance between production and removal of free oxygen radicals. Transpiration is a necessary process for photosynthesis and growth of plants but depending on the conditions may be harmful in some cases, so that the use of anti-transpirant can be one of the most effective methods for reducing the amount of water lost through transpiration and effective way to reduce the effects of drought stress on plants and adjustment the reduction of the yield due to water deficiency in arid and semi-arid regions. Climate change created in the world and the intensification of stresses caused by it, especially drought stress in arid and semi-arid regions such as Iran, make it difficult to achieve this goal. Therefore, finding strategies that can reduce the effects of water shortages on plant growth and yield and improve growth and yield can be very important. The aim of the present study was to investigate the effect of irrigation regimes and application of different concentrations of tragacanth (naturally dried exudate from some Astragalus species) on black cumin plant. Materials and Methods This research was carried out in a factorial experiment based on completely randomized design with three replications in a greenhouse of the Agriculture College of Kurdistan University in 2018. The experimental factors were including irrigation at three levels of 100% (full irrigation), 70% (mild drought stress), and 40% (severe drought stress) of field capacity of soil and spraying with tragacanth extract at six concentrations of 0, 1.25, 2.5, 5, 7.5, and 10 g/L. Spraying of this material was done using a back sprayer (Shark model) with a constant pressure of 2.4 bar and a volume of 250 liters of water per hectare. Before the data were analyzed, their normality test was performed using the Mini Tab software. After ensuring the normality of data, analysis of variance was performed using SAS ver. 9.3. LSD (Least significant difference) was used to compare the mean of treatments. The graphs are drawn using Excel software. Results and Discussion The results showed that increased drought stress intensity (irrigation reduction) led to the reduced leaf relative water content, Total chlorophyll content, efficiency of photosystem II, plant hight, number of capsules per plant, mean number of seeds per plant, biological yield and grain yield.

Ecological agriculture of medicinal plants guarantees their quality and reduces the possibility of negative effects on their medicinal quality and yield. One of the most important medicinal plant species is basil, which is widely used in food and pharmaceutical industries. Common basil (Ocimum bacilicum L.) is the most important economic species of Ocimum and is cultivated and consumed in almost all warm and temperate regions. Evaluation of different plant nutrition systems is one of the important principles in the production planning of medicinal plants in order to achieve high yield and quality of effective ingredients. Proper fertilizer management is one of the important factors in agricultural production. Identification of fertilizers compatible with nature and suitable for plant growth can have favorable effects on quantitative and qualitative indices of the plant. Organic fertilizers are genuine and risk-free products that can be suitable for agricultural sustainability. Soil organic matter improves fertility and water retention, provides proper ventilation, long-term storage of plant nutrients and microorganisms, so replacing chemical fertilizers with fertilizers such as vermicompost and biofertilizer can reduce the above-mentioned effects. Biofertilizers are one of the operations that is nowadays in accordance with the principles of sustainable agriculture for soil fertility. Biofertilizers include the compost of one or more types of useful soil organisms or as metabolic by-products of these organisms that are used to provide the plant with the nutrients it needs in an agroecosystem.Materials and Methods: In order to investigate the effect of biochar and organic and biological fertilizers on the quantity and quality of Ocimum bacilicum L., a factorial experiment was done in a randomized complete block design with three replications. Experimental treatments included two levels of biochar (0 and 20 ton ha-1) and five levels of fertilizers (vermicompost (10 ton ha-1), Mycorrhiza, Azotobacter, Pseudomonas and no fertilizer application). Prior to planting sweet basil seed, biofertilizers and vermicompost were mixed with soil to the depth of 15 cm. Mycorrhizal fungi were mixed with seed. Azotobacter and Pseudomonas bacteria were also incubated with seeds (seed inoculated). It should be added that in this study no chemicals were used to control weeds and pests. Before flowering stage, morphological traits of basil (plant height, stem diameter and number of branches) were measured. Also, to measure the dry weight of the shoots, basil was scalped from one square meter and weighed, and their fresh weight was thus determined. Then, to determine the dry weight, the samples were transferred to an oven at 70 ° C for 48 hours and finally weighed.

Thermal decomposition of biomass in an oxygen-free medium is called thermophilicity (pyrolysis). Temperature is one of the factors influencing the characteristics of biochar. One of the objectives of this experiment is to investigate the effect of different temperatures on the biochar characteristics of cattle manure. The use of biochar as a soil conditioner and source of organic carbon in agricultural soils with minimal environmental damage is considered. Marigold is an annual plant that is used in industry and pharmacy in addition to food. Another aim of this experiment is to investigate the effect of biochar use from different temperatures on marigold under salinity stress.Materials and Methods: For biochar preparation, after collecting cattle manure from Bardsir farms, air drying and sieving for four hours at temperatures (300, 400, 500, 600 ° C) were performed for pyrolysis process. Then pH, EC, carbon stability, ash and biochar performance were measured. In order to evaluate the effects of biochar resulting from different heat-treated temperatures on salinity tolerance of marigold, a factorial experiment was conducted in a completely randomized design in the greenhouse. The two factors studied included salinity levels (0, 4, 8 and 12 dS / m) and biochar resulting from different thermocouple temperatures (0, 300, 400, 500 and 600° C). The biochar rate was considered to be 20%. One month after salinity treatment, seedlings were evaluated for osmotic metabolites activity and growth characteristics of marigold seedlings.Results discussion: The results of analysis of variance showed that all biochar properties were significantly affected by temperature factor. With increasing the pyrolysis temperature to 600 ° C, pH and EC increased by 16.29% and 60.37%, respectively, and the ash content increased by 1.5 times, but biochar performance and bulk density decreased by 52.28% and 48.1%, respectively. The highest carbon stability was observed at 500 ° C, which increased by 20% compared to 300 ° C. The results showed a significant negative effect of salinity stress on stem height, number and area of marigold leaves and with increasing salinity to 12 dS / m, 31.09, 17.28 and 45.7% decrease in these traits were observed, respectively. The physiological characteristics of marigold were significantly affected by the simple and interaction effects of salinity and biochar stress.

Turfgrasses have provided functional, recreational, and aesthetic benefits to urban landscapes. Multiple benefits of turf are well documented such as recreational health, enhanced water infiltration, erosion control, mediation in heat-island effects and reduction in nutrient leaching. But the main problems of turfgrass development are the cost of turfgrass seeds, maintenance costs such as moving, as well as the high water requirement in arid and semi-arid regions. Thus, the reduction of lawn culture in the landscape is one of the decision has taken in parks and green spaces organization of Tehran, Isfahan and even Mashhad. Materials and Methods So the aim of this experiment was to compare three common turfgrasses with two clover varieties as turf replacement to reduce landscape maintenance cost specially moving cost. So, some growth factors of clover lawn: Trifolium repens var. Calway and Trifolium repens var. Pipolina (micro clover) and three turfgrasses of Festuca arundinacea L. and Lolium perenneL. and commercial sport turf mixture (from NAk-Nederland Ltd.) were compared together. This research project was conducted in randomized complete block design with three replications in the research field of the Department of Horticultural Science and Landscape Engineering‚ Agricultural Faculty‚ Ferdowsi University of Mashhad‚ Mashhad‚ Iran, during 2016 and 2017. The site (59o 38′ E and 36o 16 ′ N; elevation 989 m) is located in an arid and semi- arid region with mean annual rainfall 233.8 mm and long term averages of maximum and minimum temperature are 22.5 oC and 9.3 oC‚ respectively. Turfgrass plots were established by directly sowing the seeds in April, 2016. The planting rate of the seedling considering their pure live seeds (PLS) were 45 g.m-2 for Lolium perenne, 34 g.m-2 for Festuca arundinacea, 6.5 g.m-2 for Trifolium repens, 5.5 g.m-2 for micro clover and 39 g.m-2 for commercial mixture of sport turf. The plots were 1 m2 (1m×1m) in size and were prepared after plowing and leveling the soil. The seeds were hand sown and covered with a thin layer of leaf compost and sand. Results and Discussion According to the results in the first evaluation of emergence percentage, Lolium perenne had the highest emergence percentage. But, after 36 days from culture, all plants had 92-98 % coverage which did not have any significant difference among grasses with clover lawns. In terms of density, uniformity and weed density, there was no significant difference between the studied plants.

Genus Berberis, the biggest genus in Berberidaceae, includes more than 660 species. Barberry grows in Asia and Europe; and has been used extensively as a medicinal plant in traditional medicine. In Iranian and Turkish traditional medicine, several properties, such as antibacterial, antipyretic, antipruritic and antiarrhythmic activities have been reported with unknown mechanisms of action. Amazing structural diversity among barberries’ active components makes them a useful source of novel therapeutic compounds. Seedless barberry (Berberis integerrima ‘Asperma’) is one of the Iran’s indigenous valuable medicinal plants. Common asexual propagation of this plant over years and consequently low genetic diversity in populations of the seedless barberry restricts selection outcome in breeding programs. Utilizing the indigenous wild genotypes of barberry genus, which are easily able to cross-pollinate is one of the best methods to increase the genetic diversity. To meet this purpose, several wild seedy barberry genotypes were identified from all over the Iran, collected and established in a collection in Mashhad; then 16 genotypes were selected and their physical properties were studied. Materials and Methods: In this study mature fruits of sixteen unique genotypes (i.e. Iranian seedless barberry and fifteen seedy genotypes) were harvested in October- November, 2015 and kept in refrigerator in order to measure some of their physical properties in fresh fruits (berry dimension, weight of one hundred fresh berries, juice content and color indexes). For other properties, fruits were dried at room temperature. Fruit cluster length was measured by means of a ruler, number of berries/cluster and number of set and aborted seeds/berry by counting, berry dimensions by a digital coulis, weight of one hundred fresh and dried berries, percentage of pulp and seed as well as fruit juice content by a scale with 0.001 accuracy.

The experiment comprised ten treatments with combination of two factors. The two factors included the grafting dates including: 13th, 19th, and 26th of February, 4th and 11th of March and grafting methods including: outdoor grafting and bench grafting (tongue grafting in both). The experiment was laid out in a Randomized Complete Block Design with three replications. The findings revealed that bench grafting resulted in significantly better outputs than outdoor method for length of scion (at 30 and 60 days after grafting) and graft take rates. Bench grafting showed 44% graft take followed by outdoor grafting (38% graft take). Plants grafted on 13th and 19th of February showed statistically better results for growth performance over the other dates. Plants grafted on 19th of February showed 67% graft take with 53% saleable plants, but statistically similar to the plants grafted on 13th and 26th of February. The earliest bud burst was observed in plants grafted on 13th and 19th of February in 31 and 33 days, respectively. Bench grafting on 19th February showed significantly higher length of scion (16.4 cm) at 60 days after grafting. However, non-significant results were seen for other parameters due to the interaction. Therefore, bench grafting on 13th,19th and 26th of February led to the best graft take in Persian Walnut.Abbreviations: CV: Coefficient of Variation, LSD: Least Significant Difference, ha: hectare, mt: Metric tons, PMAMP: Prime Minister Agriculture Modernization Project, RCBD: Randomized Complete","PeriodicalId":15968,"journal":{"name":"Journal of Horticultural Science","volume":"149 1","pages":"133-147"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76350193","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 tubular structure, probably a hypocotyl, mimics an umbilical cord connecting the growing fetus with that of placenta in human embryonic development.","PeriodicalId":15968,"journal":{"name":"Journal of Horticultural Science","volume":"21 1","pages":"149-151"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75696036","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}
