Changes in fruit quality, decay, phenolic and anthocyanin content, and antioxidant capacity of strawberries (Fragaria ananassa Duch. cv. Allstar) stored under air and high oxygen atmospheres at 5 1C were investigated. Freshly harvested strawberries were placed in jars and ventilated continuously with air or with 40, 60, 80, or 100 kPa O2 at 5 1C for up to 14 days. Samples were taken initially, ...

a field study was carried out at the islamic azad university of arak in 2010 to find out the effects of salicylic acid and water deficit stress on oil yield and some physiological characteristics of different varieties of sunflower. the experiment was laid out in a factorial split plot based on a randomized complete block design with four replications. treatments consisted of water stress in th...

in order to evaluate the utilization ability of drought resistance indices such as: yield index (yi), yield stability index (ysi), stress susceptibility index (ssi), tolerance (tol), mean productivity (mp), geometric mean productivity (gmp) and stress tolerance index (sti) in sunflower hybrids, three separate experiments were conducted as randomized complete block design at the research field o...

in order to study of the radiation interception and red to far red light ratio variations in sunflower hybrids under drought stress, nine sunflower hybrids in three separate experiments were compared as randomized complete block designs with three replications at the research station of seed and plant improvement institute in karaj in 2006. first experiment (control) was irrigated based on 60 m...

in order to study the effect of water deficit effects on agronomic characteristics of sunflower ‎hybrids, three separate experiments were conducted as‏ ‏randomized complete block design with ‎three replications at the research field of seed and plant improvement institute - karaj. the first ‎experiment conducted at optimum conditions and plants were irrigated after 60 mm evaporation ‎from evapo...

Objective: Returning crop residue to the soil exerts favorable effects on physical and chemical properties of soil. In fact, the plant residues can affect soil conditions such as pH and important role in soil fertility and cycling of elements in the soil may have. In addition to the role of the organic matter from decomposition of crop residue in increasing the concentration of micronutrients i...
