to investigate the effect of different concentrations (0, 0.01% and 0.02%) of salicylic acid (sa) on some quantitative and qualitative characteristics of pomegranate fruit cultivar ‘malase yazdi’ at ripening,2 and 4month ofstorageat5°c, a factorial experiment based on randomized complete block with three replications was conducted. quantitative characteristics including percentage of fruit weig...

Seedlings of corn (Zea mays) were tested for recovery from chilling injury incurred at 0.3 +/- 0.3 C. At 0.3 C visual leaf injury appeared in 36 hours, whereas stem and root injuries appeared later. Appearance of leaf injury was preceded by a rise in O(2) uptake and a lessened effect of 2,4-dinitrophenol on O(2) uptake by leaf segments and was accompanied by increased ion leakage from the leave...

in this paper, grafting of acrylic acid monomer on gum tragacanth was performed. variable of experiment included concentration of initiators and monomer, time, and temperature. grafting efficiency was measured in the term of percentage of grafting (%g) and percentage of grafting efficiency (%e). effectiveness of grafted gum in ferrous ion removal at different condition was assessed. according t...

the interaction between sodium and calcium, magnesium and calcium and the combined effect of sodium, magnesium and calcium was observed on the growth and ion uptake of hippophae rhamnoides l. the results demonstrated that an addition of sodium with calcium, (set a, na 2.5 + ca 5 mm) showed prominent increase in fresh weight of roots and shoots. the dry weight (average) of roots decreased and th...

CFD was employed to simulate the steam flow in 1.5-stage cascades with three different seal clearances. When clearance is 0, there no leakage, obvious secondary cascade, and stage efficiency reaches 88.27%. of diaphragm rotor tip 1mm, leakage strongly interferes which promotes formation development end-wall near hub, has little effect on next stage, drops by about 2 percentage points. 4mm, hub ...
