【摘要】 强春性小麦品种在生育过程中,对温度条件要求不严格,生育早期没有低温效应。它们对日长也无严格要求,其光周期反应不具有长日植物的性质。在我国南北不同播期的不同温光组合中,都能顺利通过各生育时期,正常抽穗和开花。这种品种类型具有广泛的生态适应性,在科研和生产中均有重要的利用价值。更多还原

【Abstract】 Wheat cultivars Liaochun No.6, 76-63-1 and Yuemai No.6 are three strong spring ness ecotypes. They are insensitive to temperature in growing process and no response to low temperature in early phase of growth. These cultivars are insensitive to day-length toc. Photoperiodical reaction of cultivars has a variation. These ecctypes can pass through reproductive cycle, for instance, can heading of flowering normally in any latitude under different temperatures and illuminations in China. They can be growth in south and north areas. For their widc range of ecological adaptation, these cultivars are widely used in agricultural research and production.更多还原
