不同来源甜高粱主要性状的研究

[目的]通过比较不同来源甜高粱的主要性状,探索甜高粱的共性与特性。[方法]以农甜5号、佛甜2号、吉甜2号、京引8号为试材,对生长势、含糖量变化、植物学性状表现进行研究。[结果]不同来源的甜高粱品种在珠三角腹地均能种植,以农家品种表现较弱;糖含量积累的总体趋势是一致的,以茎中部含糖量高,其次是基部。[结论]甜高粱来源不同,优势表现的部位不同。

Study on Main Characters of Sweet Sorghum from Different Sources

[Objective] General characters and characteristics were explored through comparison of main characters of sweet sorghum from different sources.[Method] Nongtian No.5,Fotian No.2 and Jitian No.2,JIngjin No.8 were taken as test materials to study growing trend,change of the sugar content,and botany character performance.[Result] The sweet sorghum variety from different sources could be planted in the bead triangle center.The performance of the peasant family variety was the weakest.The overall tendency of the sugar accumulation was consistent.The sugar content was high in the middle stem,next was that in the base.[Conclusion] The sources of sweet sorghum were different,and the spots performing superiority were different.
