[ 1 ] - تأثیر عنصر روی و زمان برداشت بر کاهش انباشت نیترات و فعالیت آنزیم نیترات ردوکتاز در کاهو و اسفناج در محیط آبکشت

Leafy vegetables play a crucial role in human dietary. Excessive application of nitrogen fertilizer leads to accumulation of high levels of nitrate in the tissues and causes further consequence. In order to evaluate the impact of zinc and harvest times on the reduction of nitrate accumulation and nitrate reductase activity, an experiment was conducted as completely randomized design with factor...

[ 2 ] - تأثیر مقدار نیترات و زمان برداشت بر غلظت آهن، روی، مس، پتاسیم و فعالیت آنزیم نیترات ردوکتاز در کاهو و اسفناج

Leafy vegetables are considered as the main sources of nitrate in the human diet. In order to investigate the effect of nitrate levels and harvest times on nitrate accumulation, nitrate reductase activity, concentrations of Fe, Zn, Cu and K in Lettuce and Spinach and their relation to nitrate accumulation in these leafy vegetables, two harvest times (29 and 46 days after transplanting), two veg...
