笔者通过几年试验,选育出菊花新品种70余个,其中有17个在1993年中国菊花研究会第三次年会上被鉴定定名。现谈谈具体的育种方法: 1.杂交授粉方法选定父、母本后,根据菊花开放规律,从11月上旬开始剪短母本的全部舌状花瓣,内轮随花朵的开放也及时补剪,保留基部1.5厘米左右,切勿损伤雌蕊柱头。剪后套上半透明纸袋,防止自然授粉。注意观察雌蕊柱头,当呈“Y”形并具有光泽时,即可授粉。择晴天上午10~12时,用干净毛笔收集父本花粉,授于母本雌蕊柱头上。每朵花从外向内每2~3天授粉一
After several years of experiments, the author bred more than 70 new varieties of chrysanthemums, of which 17 were identified at the Third Annual Conference of China Chrysanthemum Research Society in 1993. Now talk about the specific breeding methods: 1 hybrid pollination method selected parent and female parent, according to the law of open chrysanthemums, beginning in early November cut all female tongue petals, the inner with the flowers open and timely Scissors, keep the base of about 1.5 cm, do not damage pistil stigmas. Scissors set on the translucent paper bag to prevent natural pollination. Pay attention to observe the pistil stigma, when was “Y” shape and has a gloss, you can pollinate. Select the sunny morning 10 to 12 o’clock, with a clean brush to collect the parent pollen, granted in the female pistil stigma. Each flower pollination every 2 to 3 days from outside to inside
