孕穗期渍水逆境对冬小麦干物质积累与分配的影响
0
()
摘要:
于1997~1999年在安徽农业大学试验总场进行试验,采用柱载试验,研究了孕穗期渍水逆境对小责中后期干物质积累与分配的影响。研究结果表明:孕穗期渍水逆境促使单茎绿叶衰亡加快,单茎绿叶干重、单茎茎鞘干重和穗干重下降;同时严重影响小麦中后期各器官干物质的积累、运转和分配,最终导致粒重和产量下降。

Effects of Waterlogging at Booting Stage on Accumulation and Distribution of Dry Matter in Winter Wheat
()
Abstract:
Experiments by column culture from 1997 to 1999 were carried out at the Experiment Farm of Anhui Agricultural University.The major results were as follows:waterlogging at booting stage speeded up the declination of dry weight of leaf ,stem, sheath, ear and root system,the influences upon dry matter accumulation,transportation and distribution were significant,and the grain weight and yield decreased finally
Key words:  booting stage,waterlogging,accumulation and distribution
