the role of priming on seed reserve utilization and germination of mountain rye (secale montanum) seeds under salinity stress
low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...
متن کاملEffects of seed aging on subsequent seed reserve utilization and seedling growth in soybean
Reduced seedling growth is a consequence of seed deterioration. The heterotrophic seedling growth can be considered as the product of three components: (1) initial seed weight, (2) the fraction of seed reserves which are mobilized, and (3) the conversion efficiency of mobilized seed reserves to seedling tissues. It is not clear which of these component (s) is affected by seed deterioration. To ...
متن کاملEffect of Water Stress on Seed Germination of Agropyron Elongatum, Agropyron Desertourm & Secale Montanum
Physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 MP) was studied on seed germination and plumule as well as radicule growth length in three species namely: Agropyron elongatum, Agropyron desertourm and Secale montanum. Polyethylene glycol (PEG) was used to provide appropriate water potentials. A total of 100 seeds in four replications (Petri dishes) were so...
متن کاملEffect of Seed Priming on Germination and Seedling Growth of the Caper (Capparis Spinosa) Under Drought Stress
Objective: To evaluate the effect of chemical stimuli on germination and seedling growth of Caper (Capparis Spinosa) under drought stress. Methods: Factorial experiment in a completely randomized design with four replicates per treatment were performed. First factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/L), gibberellic acid levels (500, 250 and 12...
