| 摘 要： | 在宁夏银川地区三年(1983～1985)田间试验的结果表明,小穗原基出现是小麦通过春化阶段的形态标志。小穗原基出现之前,生长锥上的突起均属叶性器官原基。温度作为春化阶段的必要条件,从出苗到生长锥伸长表现为积温效应,从生长锥伸长到小穗原基出现表现为低温效应。

| Abstract: | These field experiment were carried out three years (1983-1985) in Yin-chuan area, Ningxia.The result of experiment showed that appearance of thespikelet primordium is the morphological symbol to complete the vernaliza-tion phase of wheat. The convex of growing tip of stem belonged to theleafcharacteristic organic primordium before the appearance of spikelet pri-mordium.Temperature was looked on as necessary condition with regard tothe vernalization phase. It displayed the sum-temperature effect in theperiod from the emergence of seedling to the elongation of growing tip andthe low temperature effect in the period from the elongation of growing tipto the appearance of spikelet primordium. |
