摘要
本试验在温室条件下研究了不同光照方式及时间对不同光反应型春小麦生育进程的影响。结果表明，暗期间断对不同光反应型春小麦都具有不同程度的促进作用，表现出明显的长日效应。光敏型材料较先钝型材料长日效应明显。春小麦完成光照阶段所需的光照时数因光照方式而异。长日照条件下所需光照时数多，暗期间断所需光照时数最少，这一结果对温室管理及南繁加代具有指导意义。
The test was carried out in greenhouse to investigate the effect of light length and pattern on growth process of spring wheat. The results showed that the breaking of dark period promoted the growth processes of different photosensitive spring wheats,displaying obvious long- light effect; the long- light effect was more clear in photosensitive materials than in photoinsensitive ones;and the light - time needded to finish photostage was different among light patterns:mote in long- light and less in dark - period breaking.
