摘 要 ：本文以早籼稻、晚粳稻、籼型杂交稻等5个具有不同分蘖力的水稻品种为材料，研究了水稻分蘖芽分化发育过程中对外界环境的敏感期。结果表明：水稻分蘖芽从分蘖原基形成起，经过一幼一基、二幼一基、三幼一基、四幼一基期后、其第一叶就超过前出叶。然后伸出母茎叶鞘，长成正常分蘖。在这个过程中，三幼一基向四幼一基发展的转

Abstract:Five rice varieties (3 indica rices, a japonica rice, and a hybrid rice) were used as the material in the experiment. The sensitive stage to environmental conditions was studied during differentiation and development of tiller buds in rice plant. The results showed: After the tiller primordium was f
