The Effects of Priming on some Qualities of Seed Germination

ABSTRACT:In order to consider the effects of various priming treatments on quality of germination of corn plants type 4023, a test was performed randomly in three steps during 2012 in Laboratory of Agriculture Breeding of Plants at Faculty of Agriculture of University of Agricultural Science and Natural Resources of Sari. Studied treatments include osmopriming (poly ethylene glycol 6000 (PEG) with 5%, 10% and 15% concentration, potassium nitrate (KNO3) with 1%, 2% and 3% concentration, potassium chloride (KCL) with 1%, 2% and 4% concentration) and hydropriming (distilled water) in two 12 and 24-hour periods. Results showed that the qualities of germination rate, germination index, mean germination time, germination percentage and normal germination percentage are meaningful at 1% probability level. The average comparison table also indicated that the maximum germination rate and germination index are obtained by H2O treatment during 12 hours, and maximum mean germination time is obtained by KCL 4% and PEG 15% treatment during 24 hours. Consequently, hydropriming has the most effect on germination.
