摘　　要：选用3个不同类型小麦品种,系统分析了小麦品种间干物质积累、分配的差异及其与产量的关系。结果表明,供试品种干物质积累均呈"S"型趋势,品种间干物质积累差异主要表现在小麦返青后。百农矮抗58干物质积累量大,向籽粒分配和运输的比例也较大。分蘖力强、分蘖成穗率高、成穗数多、穗粒数多、开花后保持较高的平均灌浆速率是百农矮抗58实现高产的生理基础。3 different types of wheat varieties were tested to analyze the relationship between their accumulation and distribution of dry matter and grain yield. The results showed that the dry matter accumulation of tested varieties presented the S type and the difference in dry matter accumulation of tested varieties mainly occurred after their reviving. The physiological basis of Bainong AK58 with high yield includes its strong tillering ability, higher effective ear rate and higher average filling speed because of its higher proportion of grain distribution from its higher dry matter accumulation.
