| 摘 要： | 为探讨小麦成熟期过度淋雨对种子质量的影响,以10个小麦基因型为试验材料,在连阴降雨(降雨量为53.6mm)条件下,对淋雨前后种子千粒重、发芽率、幼苗形态生理性状进行了测定分析。结果表明:(1)过度淋雨对种子千粒重影响显著,淋雨前比淋雨后10个基因型平均高2.58g,幅度为5.51%;(2)过度淋雨对种子发芽率也有显著影响,淋雨前比淋雨后10个基因型平均高28.4%;(3)过度淋雨前后的种子幼苗形态生理特性差异显著,10个基因型平均根长、根条数、苗高、鲜重和干物重前者均显著优于后者。

| Abstract: | 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 eaehl0 genotypes ,range 5.51% ; （2） Exces- sive rain makes a significant impact on germination rate ,28.4% higher on average after the rain eaeh 10 genotypes; （3）The physical characteristics of seeding is very different before or after excessive rain , after the rain , the average of the length and number of root ,the fresh weight and dry weight are obviously poorer each 10 genotypes. |
