Abstract:

In order to accurately grasp the best time for cross pollination of Asparagus officinalis,the variation law of pollen viability and stigma receptivity of three Asparagus officinalis varieties with good character and dioecious type was studied. The results showed that there were great differences in pollen viability of male flowers and stigma receptivity of female flowers among these Asparagus officinalis varieties. When the sampling time was fixed,the pollen vitality of male flowers of CA FCE2*M256 and Fengdao 1 reached its highest at flowering stage 2 d. At the day of natural flowering,the diurnal variation of pollen viability was different among varieties:CA FCE2*M256 reached its highest value at 08:00,Grande reached its highest value at 16:00,and Fengdao 1 reached its highest value from 12:00 to 14:00. The stigma receptivity of female flowers showed no significant differences among varieties and reached its peak at flowering stage 1 d. It can be concluded that when Asparagus officinalis varieties are used for cross breeding,pollen from male flowers with a certain degree of openness should be selected at an appropriate time to pollinate female flowers at flowering stage 1 d,in order to achieve a higher success rate of pollination.
