【摘要】 [目的]为帚用高粱高产育种提供理论依据。[方法]以国内搜集的11种帚用高粱为研究对象,通过对株高、分蘖、花序、茎节、茎叶比、产量等指标的调查,比较其形态特征差异。[结果]11种帚用高粱在形态特征上存在差异性,株高变幅很大,zygl-1、zygl-6、zygl-8、zygl-9适宜固定帚型,zygl-9综合产量最高。[结论]该研究为进一步探讨帚用高粱的育种、栽培、推广奠定了基础。更多还原

【Abstract】 [Objective] To provide a theoretical basis for high-yield breeding of broom sorghum.[Method] Using 11 kinds of broom sorghum collected at home as research objects,the differences in morphological characteristics of broom sorghum were compared through the survey of some indicators,such as plant height,tillering,inflorescence,stem node,stem-leaf ratio,yield,and so on.[Result] The 11 kinds of broom sorghum were different in morphological characteristics with large amplitude of plant height;zygl-1,zygl-6,zygl-8 and zygl-9 were appropriate for fixed broom type;zygl-9 was of the highest integrated production.[Conclusion] The study laid the foundation for further exploring breeding,cultivation and promotion of broom sorghum.更多还原
