北方强冬性小麦田间春化和在贵州种植的可能性

本文以贵阳、北京两地1982—1985年秋播试验为依据,阐明北方强冬性小麦品种在两地均能通过春化反应正常成熟,在冬季短日配合下,冬小麦可以在较宽范围低温条件下通过春化阶段,短日对春化有促进作用。北方强冬性小麦在贵阳的生育期比北京短,某些性状似优于北京点的表现,为贵州开发利用冬型品种,提出了可行性依据。

The field-vernalization of northern winterness wheat and its possibility for planting in Guizhou

According to the result of ecological research on the winterness wheat sowing at autumn from 1982 to 1985 in Guiyang and Beijing, The northern winterness wheat varieties could pass through vernalization and maturity normally at autumn sowing in different date. This experiment also indicated that the northern winterness wheat could pass through vernalization within a more wide lower-temperature when the condition join short-day photoperiod in winter season. Short-day accelerated vernalization process for winterness wheat. The duration of northern winterness wheat in Guiyang is more shorter than in Beijing and some characters of northern winterness wheat in Guiyang is also superior to Beijng. Such as these characters povide sientific basis for make rational use northern winterness wheat resource in Guizhou.
