初步研究了橡胶树花培无性系人工授粉的结实、种子成苗及授粉苗的生长和遗传表现情况。结果表明 ,花培无性系和非花培无性系两者之间 ,除稔实率基本相当外 ,前者的采果率、种子成苗率明显低于后者 ,杂交后代中白化苗的比例明显高于后者 ;前者的 1年生授粉苗的生长高度与后者无显著差异 ,但整齐程度明显不及后者的 ;花培无性系授粉苗的染色体数目无异常表现 ,不同亲本组合授粉苗的过氧化物酶同工酶谱带也无明显差别
The growth and genetic performance of rubber tree seedling clones artificial pollination, seedling and pollination seedlings were preliminarily studied. The results showed that, except for the seed-setting rate of clonal and non-flowering clones, the fruit-picking rate and seedling rate of the former were significantly lower than the latter, and the proportion of albino seedling in hybrid progeny was significantly Higher than the latter; the former one-year-old pollination seedlings height growth with the latter no significant difference, but the degree of neatness was significantly less than the latter; flower culture clones pollination number of chromosomes showed no abnormalities, different combinations of parent pollination seedlings Oxidase isoenzyme bands also no significant difference
