welsh onion (allium fistulosum l.) is one of the important vegetable crops in china. however, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. the present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (kno3) on seed vigor and on other such related mechanisms during twelve months of stora...

A series of experiments were conducted in laboratory at The University of Agriculture, Peshawar to determine the optimal duration and maximal concentration of zinc (Zn) and phosphorus (P) for priming wheat seed. The seeds were soaked through a range of durations (0, 12, 18, 24, 36 and 48 h) and tested for germination as surface dry and dried to original moisture (12%). Seed soaked for 18 h resu...

In order to evaluate the effects of priming materials and duration of priming on the seed physiological enhancement and biochemical traits of germination in pumpkin seeds a factorial experiment was conducted based on a completely randomized design with three replications at the University of Mohaghegh Ardabili. Treatments were priming with water, NaCl (3%), gibberellic acid (20 mg L-1), and asc...

BACKGROUND AND AIMS Early flooding helps control weeds but reduces seedling establishment in direct-seeded rice (Oryza sativa). When combined with appropriate management practices, the use of genotypes that better tolerate flooding during emergence can enhance crop establishment in flood-prone areas. Management options include seed pre-treatment and we tested the influence of pre-soaking for 24...

seeds of most crops including those of range plants follow orthodox behavior. however, these seeds undergo aging even under favorable conditions, so that decreased viability and vigor related parameters are the main characteristics of deteriorated seeds. the effects of hormonal priming with auxin, cytokinin, gibberellin and abscisic acid at 0, 50, 100 and 150 ppm on physiological quality of tal...

Welsh onion (Allium fistulosum L.) is one of the important vegetable crops in China. However, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. The present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (KNO3) on seed vigor and on other such related mechanisms during twelve months of stora...

The growth and performance of cowpea seedlings are negatively impacted by climate change the subsequent occurrence drought stress. Osmotic stress leads to formation reactive oxygen species, causing membrane breakdown, impairs metabolic activities. harmful effects osmotic can be reduced using seed priming techniques. Seeds var. Anaswara were treated with polyethylene glycol (PEG) ?-amino butyric...

Effects of hormonal priming with abscisic acid (ABA), salicylic acid (SA), or ascorbic acid on wheat (Triticum aestivum cv. Auqab 2000) germination and seedling growth under normal (4 dS/ cm) and saline (15 dS/ cm) conditions were studied to determine their usefulness in increasing relative salt-tolerance. During germination test, most of treatments were effective in improving germination and s...
