damage caused by freezing can be the result of differences in cellular processes, including changes in membrane properties, interactions between macromolecular and enzymatic reactions. in this experiment, total soluble solids (tss) and relative water content of the reproductive buds of cultivars “j. h. hale”, “elberta,” “redhaven, ” “sorkh sefid mashhad” and “amsden” peaches, along with nectari...

to study the effect of sucrose and calcium chloride on the quality and longevity of cut flower of rose cv. varlon, this experiment was conducted at the faculty of agriculture, zanjan university, zanjan, iran, in 2007. cut flowers were received from mahallat ornamental plants and flowers research station. experimental factors included: sucrose at four levels (0, 40, 80 and 100 mg/l) and calcium ...

in this study, the winter cold tolerance of seven strawberry cultivars was evaluated using a rcbd design with a split plot arrangement at bu-ali sina university in 2014. after exposure of plants to low temperatures (+4, -5, -10, -15, -20 and -25oc), the values of electrolyte leakage, index of freeze injury, rwc, total chlorophyll and chlorophyll fluorescence parameters (f0, fm, fv and fv/fm) we...

Salicylic acid (SA) is a key molecule that alleviates abiotic stress in many plant species. In this study, the role of SA was examined to moderate lead (Pb) toxicity in the basil (Ocimum basilicum). The experimental design was a randomized complete block design with 4 levels of PbNO3; 0 (control), 100, 200 and 300 mg kg-1 of soil as the first factor, and the foliar application of SA at 3 levels...

One of the major abiotic stresses limiting the productivity and the geographical distribution of many important crops is low temperature. 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...

the present study was conducted to evaluate the effect of ascorbic acid (asa) as an important antioxidant in alleviation of salt damage in oregano (origanum majorana l.). this research work was carried out at the research greenhouse of ferdowsi university of mashhad. foliar application of asa (0, 100, 200 mg/l) was carried out on the plants that were under salt stresses of 0, 50, 100 and 150 mm...
