摘要
利用麦穗离体培养技术 ,研究了不同蔗糖浓度和不同生长调节剂处理对籽粒形成和生长的影响 ,结果表明 ,开花后的早期阶段 (籽粒形成期 )是决定穗粒重的关键时期 ,此期蔗糖供给和激素水平的变化对穗粒数和粒重均有显著调控作用。蔗糖与激素以及不同激素之间对籽粒生长的互作调控关系需要进一步研究。
The effects of sucrose concentrations and different kinds of plant growth regulators on the setting and filling of grains were investigated, with detached wheat ears growing in liquid culture. The results showed that the grain formation stage, about 10-12 days after flowering, was critical for the determination of grain weight per ear, and at the stage, the change of sucrose supply and hormone levels significantly affected both grain number and grain size in wheat ear. It is necessary furtherly to research the interaction of sucrose and hormones in the regulatio of wheat grain growth.
