| 摘 要： | 目的]寻找甜高粱与粒用高粱主要性状的异同。方法]选用代表性甜高粱T26T、37品种,粒用高粱R123、LR198品种,研究其生长势、植物学性状表现、含糖量、叶绿素含量、呼吸速率。结果]结果表明,甜高粱生长优势显著优于粒用高粱,主要表现在与生物产量有关的性状;糖含量的积累起点及总含量均高于粒用高粱,而甜高粱和粒用高粱糖积累总趋势是一致的;甜高粱生物产量优势强,而粒用高粱穗部性状优势强;生理性状中叶绿素含量粒用高粱优于甜高粱,而呼吸速率甜高粱偏高。结论]甜高粱与粒用高粱功能不同而用途不同。

| Abstract: | Objective] The similarities and differences of main characteristics between the sweet sorghum and the grain sorghum were searched.Method] Sweet sorghum T26,T37 variety,grain sorghum R123,LR198 variety were selected representatively.The growing trend,the botany character,the sugar content,the chlorophyll content,the breath speed were studied.Result] The results showed that the sweet sorghum growth obviously surpassed the grain sorghum.The sugar content accumulation beginning and the total content were higher than the grain sorghum, but the sweet sorghum and the grain sorghum sugar accumulation general trend was consistent.Sweet sorghum biology yield was superiority,but grain sorghum ear of characteristic was superiority.In the physiological character,the chlorophyll content grain sorghum surpassed the sweet sorghum,but sweet sorghum was higher in the breath speed.Conclusion] The function of the sweet sorghum and the grain sorghum was different,but the use was different. |
