Hydrogen sulfide (H2S) is an important signaling molecule involved in several stress-resistance processes such as drought, salinity and heavy metal stresses in plants. The aim of this study was to investigate the effects of exogenous H2S on improving chilling tolerance of cucumber seedlings. The results indicated that seedlings exposed to chilling stress (4 oC) increased the level of electrolyte leakage, lipid peroxidation, hydrogen peroxide, proline content and guaiacol peroxidase (GPX) activity; while sugar soluble content decreased. Pretreatment with sodium hydrosulfide (NaHS), a hydrogen sulfide donor, slightly reduced the malondialdehyde content, hydrogen peroxide content and electrolyte leakage, which were induced by chilling stress and also elevated the activity of antioxidant enzymes, soluble sugar and proline levels, and reduced glutathione content in plants under chilling stress condition. Pre-treatment with other Na+ and sulfur-containing components including Na2S, Na2SO4, Na2SO3 showed no significant effect on lipid peroxidation and hydrogen peroxide content under chilling stress. It can be concluded that the effect of NaHS pretreatment on alleviation of cold stress damages is probably related to its ability to release H2S because Na+- or sulfur-containing compounds (except NaHS) had no similar effects on alleviation of chilling damages.","PeriodicalId":15968,"journal":{"name":"Journal of Horticultural Science","volume":"22 1","pages":"199-211"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88942974","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}

Moreover, peroxidase (POD) and superoxide dismutase (SOD) enzymes activity, leaf ion leakage, and soluble carbohydrate and proline content increased significantly under osmotic stress. Application of PGRs had a significant effect on all the studied traits (except for SOD activity). Interactive effects of salinity and PGRs were significant on all the traits except for leaf ion leakage, POD activity, soluble carbohydrates, and protein. The highest total phenol and vitamin C contents were obtained with 15 mM salinity along with foliar application of PGRs.

These techniques are essential tools for the production of transgenic plants and high-value phytochemicals. The present study was planned to introduce an efficient in vitro propagation for purple passion fruit(Passiflora edulis Sims.). To do so, the effect of different plant growth regulators was investigated on micropropagation medium of purple passion fruit. For proliferation stage, nodal segments were cultured in media supplemented with various combinations of different plant growth regulators including: BA (0, 2.2, 4.4 and 8.9 μM), TDZ (2.3, 4.5 and 9.1 μM), GA3 (0 and 2.9 μM) and IBA (0 and 0.5 μM).  For rooting, shoots with about 1.5 cm long originating from explants were removed and cultured in half-strength MS medium containing different concentrations of auxin-based plant growth regulators including: IAA (0, 1.1, 2.9, 5.7 and 11.4 μM), IBA (1, 2.5, 4.9 and 8.9 μM), and NAA (1.1, 2.7, 5.4, 10.7 μM). For the proliferation stage, the best plant growth regulator combination was 8.9 μM BA+2.9 μM GA3+0.5 μM IBA, resulting in the maximum shoot proliferation, number of shoots per explants, and shoot length. Half-strength MS medium supplemented with 5.4 μM NAA or 8.9 μM IBA was the most effective treatment for the rooting of shoots. Gradual acclimatization of the rooted plantlets was performed and the plantlets were established in the soil successfully. The micropropagated plants did not exhibit any visually detectable variation to their mother plants.","PeriodicalId":15968,"journal":{"name":"Journal of Horticultural Science","volume":"4 1","pages":"305-314"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73029100","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}

Tomato (Solanum lycopersicum) is one of the most important greenhouse products. Heirloom tomato cultivars lack disease genetic resistance and are particularly susceptible to epidemics in the field. Grafting can be used to unite the soil borne disease resistance and enhanced vigor of hybrid tomato cultivars with the high fruit quality of heirloom cultivars. There are deficiencies in vegetable grafting including skills for grafting operation performance and after the grafting, having enough knowledge to select rootstock, farm management in application of required fertilizers, graft incompatibility, excessive vegetative growth of grafting plant and physiological abnormalities, and fruit quality reduction. For grafting herbaceous plants such as vegetables, depending on the type of plant, plant size, grafting purpose, available equipment, preference and experience of the grafting plant producer and  post-grafting management, different grafting methods have been introduce which is for different species and the used method is completely different. Each method has its own advantages and disadvantages, which are effective in the survival and development of grafting plants. This experiment was conducted in order to evaluate the effect of grafting methods on yield and vegetative growth of tomato plants.   \u0000Material and Methods: Three common grafting methods, splice, cleft and approach grafting were evaluated for tomato \"SV 8320\" cultivar grafted on \"Rimac\" rootstock. Executive operations were conducted in a completely randomized design with three replications at greenhouse of Lorestan Agriculture Faculty. Plant height, number of auxiliary shoot, number and length of internodes, number of fruit cluster, number of flower in cluster, root fresh and dry weight, number of fruit cluster, number of fruit in cluster, width and diameter of fruit, fruit weight, fruit fresh and dry weight, length of fruit tail, fruit tissue firmness, total soluble solid, pH, diameters of hypocotyl, pre, middle and total yield , ratio of the marketable fruits to second degree fruits, and fruit tissue firmness were recorded.
