摘　　要：以大穗型、中间型和多穗型小麦品种(系)为试材,研究其地上部和籽粒干物质积累动态。结果表明:不同类型品种地上部及籽粒干物质积累速度和总量不同。多穗型品种地上部干物质积累最多,产量也最高,中间型次之,大穗型最低。988044、02-48和01-35“源”比较充足,8355、4133-2和6200(8)相对较小,且以6200(8)“源”最小。The experiment was conducted to study the dry matter accumulation of plant and grain using large-ear,middle-ear and many-ear cultivars （lines） of super wheat. The results showed that the dry matter accumulation rate and total quantity were different in different genotype cultivars. The large-ear cultivars had the most plant dry matter accumulation and yield, and then the middle-ear and many-ear cultivars in order. The source of 988044,02-48 and 01-35 culticvars were plentiful,while that of 8355,4133-2 were less,and 6200（8） was the least.
