本文对种植在一定土壤湿度范围内的几个小麦种的产量因子进行了评价。其目的是确定改变土壤湿度对籽粒产量的影响机理,特别是对于那些已被鉴定为稳产和抗旱的小麦种,即T.sphaerococcum,T.vavilovii和普通小麦c306。本研究表明,穗粒数是小麦种T.sphaerococcum和T.vavilovii的产量稳定因子,而单位面积的穗数则是普通小麦C306的产量稳定因子。因而可用于干旱条件下提高籽粒产量稳定性的特殊产量因子之遗传质源。
In this paper, the yield factors of several wheat cultivars planted in a certain soil moisture range were evaluated. Its purpose was to determine the mechanism by which soil moisture was altered to affect grain yield, especially for those wheat species that have been identified as stable and drought tolerant, namely T. sp., Cup., T. v. V. Varvilii and C. ct. This study showed that grain number per spike was the yield-stable factor of T.sphaerococcum and T.vavilovii in wheat, while the number of panicles per unit area was the yield stability of common wheat C306. Thus, it can be used as a genetic source for special yield factors that increase the stability of grain yield under drought conditions.
