摘　　要：以7个小麦品种为试验材料,研究其主要器官干物质在干旱胁迫条件下发生的相应变化。结果表明,穗粒重受影响最小,依次为颖壳质量、茎秆干质量和叶片干质量。叶片和颖壳在干物质积累上收支平衡,茎秆是籽粒干物质积累的部分来源。This essay mainly researched the corresponed resposnse of vital organs of wheat using 7 wheat cultivars under the drought stress.Results showed that grain weight was least affected by drought and then glume weight,straw drought weight,leaves dry weight respectively.Leaves and glume drew a balance in the dry matter accumulation.Straw was the part source of the accumulation of the grain.
