Effect of Priming on Germination Characteristics of Wheat Seeds
1 Faculty member,Agricultural and Natural Resources Research Center of Yazd, Yazd, Iran ABSTRACT. Seed germination and seedling growth are critical stages in the life cycle of a plant, especially under adverse abiotic stresses. Seed germination negatively affected by stress conditions. Seed priming techniques have been used to increase germination characteristics and improve germination uniform...
متن کاملThe effect of salicylic acid and gibberellin on enzyme activity and germination characteristics of wheat seeds under salinity stress conditions
ABSTRACT: Seed priming was used in wheat seeds to increase germination characteristics and tolerance on stress exposure. Wheat seeds were treated with salicylic acid and gibberellin. After 8 days our results showed that, seed priming treatments significantly (p≤ 0.01) affected germination percentage, normality seedling percentage, germination index and seedling length. Seed priming with salicyl...
متن کاملShort Communication EFFECT OF SOME INDIGENOUS PLANT EXTRACTS ON THE GERMINATION OF WHEAT SEEDS
An experiment was conducted to determine the effect of some indigenous plant extracts on the germination of wheat seeds. Six locally available indigenous plants namely. Bazna (Zanthoxylum rhetsa Roxb.), Ghora-neem (Melia sempervirens L.), Hijal (Bartingtonia acutangula L.), Karanja (Pongamia pinnata L.), Mahogoni (Swietenia mahagoni L.) and -Neem (Azadirachta indica A. Juss.) were evaluated. Le...
متن کاملRhythmicity in Nitrate Reductase Activity in Wheat Embryos during Germination
Nitrate reductase (NR) activity, induced by germination in KNO3 showed a strong rhythmicity during the early stages of germination of wheat embryos. Peaks of activity occurred approximateiy every 12 h. Tbere was no relationship hetween the amounts of nitrate in tbe embryos and enzyme activity. Tbe fluctuations in enzyme activity did not appear to be due to reversible inactivation of the enzyme....
متن کاملEffect of Priming on Germination and Enzyme Activity of Achillea vermicularis Seeds after Naturally and Accelerated Aging
Ageing induces seed deterioration expressed as the loss of seed vigor and/or viability. Priming treatment, which consists in soaking of seeds in a solution of low water potential, has been shown to reinvigorate aged seeds. An experiment was conducted to evaluate the effects of naturally and accelerated aging on seed germination traits and enzyme activities (proxidase, catalase and superoxid dis...
