Comparative Study on the Methods for Restoring the Vigor of Aged Seeds of Radish
摘要
Abstract
Comparing their ability of different plant growth regulators to restore the vigor of aging seeds will provide evidence for the recovery of aging seeds vigor and germplasm resources conservation.The aged seeds of two radish cultivars were treated by 7 plant growth regulators or chemicals,including gibberellins(GA3 ),6-benzylade-nine(6-BA),1-Naphthaleneacetic acid(NAA),15% paclobutrazol WP ,salicylic acid(SA),KH2 PO4 and polyethy-lene glycol(PEG)at different concentrations.The germination potential,germination percentage,germination index and vigor index were employed to evaluate their effects on seed vigor recovery.The results showed that GA3 ,6-BA, NAA,SA,KH2 PO4 and PEG improved the seed vigor to some extent,and the effects of 300 mg/L PEG and 100 mg/L GA3 treatments were better than that of other methods.And if the seed basic vigor is high,GA3 treatment can get the best effect,and for the lower vigor seeds,the effect of PEG treatment is better.This result may be due to the aging degree of different seeds which have different physiological and biochemical status inside.关键词
