花生生产和杂交育种上普遍存在着开花多而受精率低的现象,一般自然受精率在60%左右,而人工授粉更低,仅在30%左右.这对于提高花生产量和杂交育种效果都是值得研究的问题。为此,我们于1977—1978年开展这方面的有关研究.供试品种:早熟珍珠豆型伏花生和花11,早熟中粒普通型花28和晚熟普通型大花生即 墨爬蔓.试验方法:(1)人工培养法,即将花粉撒在含有15％的蔗糖和1%的洋菜的培养基上,然后置于30℃的温箱中培养二小时,在120倍的普通光学显微镜
Peanut production and crossbreeding generally prevalence of flowering and fertilization rate is low, the general natural fertilization rate of about 60%, while artificial pollination is lower, only about 30% .This is to improve the yield of peanut and hybrid breeding effect is Worth to study the problem. For this reason, we carried out relevant research in this field from 1977 to 1978. Species tested: Early perennial pea bean peanut and flower 11, early maturing mid-grain common flower 28 and late-maturing common peanut Jimo Climbing.Methods: (1) artificial cultivation method, ie, the pollen is sprinkled on a medium containing 15% sucrose and 1% agar and incubated in a thermostat at 30 ° C for two hours. After 120 times of ordinary light microscope
