Seed dormancy is the major challenge in cultivation of Amaranth and Cleome gynandra. C. gynandra are affected by chemical, physical, physiological dormancy. The current study was conducted at Marondera University Agricultural Sciences Technology (MUAST) farm 2021 2022. effects gibberellic acid potassium nitrate seed treatments on emergence seedling vigour were evaluated. Seeds pre-soaked (contr...

nitric oxide (no) is a simple ubiquitous signaling molecule and plays important roles in almost every biological system. recent evidences suggest that no may act as an endocrine molecule. the aim of this review is considering available literature on endocrine roles of no and/or its metabolites, i.e. nitrite and nitrate. existing data suggest the idea that no is a hormone that after production i...

‘Golden Delicious’ apples were vacuum infiltrated (250 mm Hg) with 0, 4, and 6% solutions of CaCl2 followed by heat treatment for 0, 48 and 72 hours at 38oC. Treated fruits were stored at 0oC with RH of 85-90% for 2.5 and 5 months, followed by one week of storage at 20C. The results showed that fruits treated with 4 and 6% of CaCl2 significantly increased calcium content of fruits after 2.5 an...

The present study investigated the effect of one bout of moderate-intensity exercise on the adrenergic receptor-dependent and -independent vasoconstrictor response in rat aortas, and the role of nitric oxide (NO) bioavailability on these vasomotor responses. One group of rats was submitted to a 60 min of exercise at approximately 60% of maximal exercise capacity on a treadmill (exercise group) ...

Nitrate reductase activity in excised embryos of Agrostemma githago increases in response to both NO(3) (-) and cytokinins. We asked the question whether cytokinins affected nitrate reductase activity directly or through NO(3) (-), either by amplifying the effect of low endogenous NO(3) (-) levels, or by making NO(3) (-) available for induction from a metabolically inactive compartment. Nitrate...

An outdoor pot experiment was carried out in sand+ coco-peat culture (80:20 ratio) to investigate the response of nitrate reductase activity and nitrate accumulation in roots and leaves of fifteen Iranian landraces of spinach (Spinacia oleracea) at different stages of plant development. Plants were tested during a three periods from 22, 30 and 38 days after emergence of first true leaves and be...

Aim The inorganic anions nitrate and nitrite are oxidation products of nitric oxide (NO) that have often been used as an index NO generation. More than just being surrogate markers NO, nitrate/nitrite can recycle to bioactive again. Nitrate is predominantly eliminated via the kidneys; however, there less knowledge regarding tubular handling. aim this study, part a large randomized controlled tr...
