摘 要 ：用同位素~(15)N、~(32)P 示踪研究证明,谷子灌浆阶段植株对 N、P 元素的吸收量各品种之间有较大的差异,多花晚熟型品种日本60日谷及其杂交后代吸收量较大,但向穗部的运转速度较慢;早熟型新农761谷吸收量虽少,而向穗部运转快,并且这种特性可以遗传给其杂交后代;示踪~(15)N、~(32)P 向穗部的运转速度与当时的气温变化没有相关性

Abstract:The ~(15)N,~(32)P radiolabelled study proved that the differences of N,Pelements by millet plant in milking stage were significant among variousvarieties.In late variety“Japan 60-day”and its filial generations theamount of absoring capacity was quite large,but the translocation velo-city towards t
