In this paper,To investigate the influence of over-rained about seed quality in maturation stage of wheat,ten genotypes are studied,in constant rain(rainfall 53.6 MM) conditions,the rain before and after the seed weight,germination rate,seeding morphology physiological traits were measured.The results showed that,(1)Excessive rain makes a significant impact on seed′s 1000-grain weight,2.58%higher on average after the rain each10 genotypes,range 5.51%;(2)Excessive rain makes a significant impact on germinati...
