| Abstract | ||
| Seeds Viability and seed vigor decline during storage, So a lab experiment was carried out in the Seed Testing and Certification Office-Ministry of Agriculture, to improve performance of stored maize seeds (cultivar; Baghdad 3) for different periods of storage (1,2,4 years) in open storage type, by using several methods of seeds priming with (distilled water, polyethylene glycol (6000 PEG) 100g/litre-1, potassium chloride (KCl) 20gm/litre-1, ascorbic acid (ASA)30 mg. litre-1 and gibberellic acid (GA3) 300 mg.litre-1) for 24 hours, then dried for 48 hours at room temperature, in addition to (unprimed seed treatment (control) to know their effect on Viability and vigor of Seeds and determine the best one on them, using a factorial experiment with CRD completely randomized design in three replications. The results showed that seed priming with gibberellic acid was significantly superior in germination percentage of first and final count, germination speed, mean germination time, radicle and plumule length and in fresh and dry weight of radicle and plumule, (50.2%, 88.4%, 19.2seedling.day-1,4.7day, 16.8 cm, 16.0 cm, 1041.1 mg, 97.5 mg) respectively. Stored seeds for one year treatment was significantly superior in all parameters of this study (germination percentage in first and final count, germination speed ,the mean germination time, length radicle and plumule and in fresh and dry weight of radicle and plumule) as given (48.9%, 89.3%, 19.2 seedling.day-1,4.9 day, 16.3cm, 14.2cm, 1067.2mg, 90.6mg) respectively. The results showed a significant effect of the interaction between seed priming treatments and seed storage duration in most the parameters of this study. It can be concluded from this study that maize seed priming led to improve vigor and Viability of seeds for all the seed storage duration. Also stored maize seed priming with gibberellic acid 300mg.litre-1 was the best compare with the other method of seed priming. | ||
