依据烤烟开花习性,进一步研究烤烟蒴果的发育、成熟过程对产种量及种子质量的影响等问题,对进一步搞好良种繁育工作是很有参考价值的,本文将根据多年实验资料,谈谈有关问题,供大家参考。一、蒴果发育过程及形态特征烤烟蒴果为同锥形,长约2厘米,宽1厘米,具二室。全株蒴果成熟顺序与开花顺序大体一致。单蒴发育情况是:自花冠盛开后二天花冠管基部开始萎褐,七～八天即达
Based on the flowering habits of flue-cured tobacco, further research on the development and maturation of flue-cured tobacco capsules on the yield and quality of seeds is of great reference value for further improvement of breeding programs. Based on years of experimental data, Questions for your reference. First, the process of capsule development and morphological characteristics Flue-cured tobacco capsule with the cone, about 2 cm, 1 cm wide, with two rooms. Whole-plant capsule maturation sequence and flowering sequence is generally consistent. Single bolt development is: two days after the crown of corolla tube begins to wilt, seven to eight days up
