摘 要 ：对陕西关中小麦品种同化物积累分配特性及源库构成的遗传改良进行了分析。结果表明，在关中小麦品种更换中生物学产量的提高主要是开花前生物学产量的显著提高，品种演变中开花前积累的干物质在开花后的输出率显著增加，这对籽粒产量的提高有十分重要的作用。源库构成的分析表明，关中小麦品种在源库性状上存在着较大的遗传差

Abstract:The genetic improvement of assimilate accumulation and distribution and source-sink constitution was analyzed in wheat vatieties grown in Mid-Shaanxi area. The results showed that the increase of biomass was mainly due to the biomass before anthesis in variety substitution. The output rate of dry ma
