延衰剂对小麦开花后物质积累运转的调节效应

Effect of Antiager on Matter Accomulation and Transfermation after Flowing in Wheat

在小麦开花期和麦粒形成期喷施延衰剂，结果表明，不同处理延衰剂均可提高花后物质积累量和花前物质向籽粒运转率，对防止小麦后期早衰，提高籽粒中后期灌浆强度，增加粒重均有明显的调节作用。

The experiment was conducted at the flowing and grain-filling stages in wheat with applying antiagers.The results showed that the antiagers increased the matter accomulation after flowing and the transfermation rate of matter before flowing to grain,enhanced the grain filling rate,prolonged the period of grain filling and increased the grain weight among the different wheat varieties.
