采用扫描电镜,对刺玫月季育种中使用的5个杂交亲本和3个F_1杂种花粉,进行观察和研究。通过对花粉形态的比较研究,讨论花粉败育对刺玫月季育种的影响,及亲本与杂交种在花粉外壁纹饰上的相关性。
Using scanning electron microscopy, five hybrid parents and three F1 hybrid pollen used in the breeding of Rosemary roseus were observed and studied. Through the comparative study of pollen morphology, we discuss the effect of pollen abortion on rose breeding and the correlation between parents and hybrids on pollen exine ornamentation.
