一、花粉的人工培养1.花粉的培养利用。棉花花粉的自然萌发,是指开花后花药开裂,花粉散落在柱头上的萌发,这在第三章已经谈到。一般在正常开花的情况下,若不遇雨、高温或低温等异常条件,花粉散落到柱头后便可很快萌发,长出花粉管,棉花的花粉也可进行人工培养萌发。花粉经过贮藏保存以后,或者为了杂交的需要进行远距离运送后,需检定花
First, artificial pollen cultivation 1. Pollen cultivation and utilization. The natural germination of cotton pollen refers to the anther dehiscence after flowering and the germination of pollen scattered on the stigma, as we saw in Chapter Three. Normally under normal flowering conditions, unless abnormal conditions such as rain, high temperature or low temperature, the pollen can germinate quickly after being scattered on the stigma and grow pollen tubes. Pollen of cotton can also be germinated by artificial cultivation. After the pollen is stored for storage or for long distance delivery for hybridization, the flower needs to be checked
