Abstract
In order to explore the interactions between nitric oxide(NO)and aquaporin(AQP)in seed germination,twowheatvarieties includingShaanhe No.6(SH6,drought-resistant)and ZhengyingNo.1(ZY1,drought-susceptible)were adopted to study the effectsofH2O,HgCl2(500μM),PEG(PEG-8000,-0.35MPa),SNP(0.5 mM), SNP+PEG and SNP+HgCl2solution soaking on seed germination.The results showed that SNP(NO donor)promoted seed germination of the drought-resistant variety,while inhibited that of the drought-susceptible variety.AQP played a more important role in the drought-susceptible variety than in the drought-tolerance variety.NO could relieve the inhibition of seed germination caused by droughtor aquaporin inhibitor(HgCl2).The inhibition degree of stress to germination of the seeds being imbibedwas smaller than thatof the seeds beinggerminated directly.NO could regulate the activity of AQP,and both NO and AQP exerted their role mainly in the initial 12 h of germination.
