秈稻花培的绿苗率是受各种因子所综合控制的,应用适当的诱导培养基和分化培养基.对花药进行低温予处理等.较好地发挥了综合因子的增效作用.因而使秈稻花培绿苗率提高到了1.7%.禾谷类通用诱导培养基和M_3型的分Ⅰ、分Ⅱ、分Ⅲ培养基以及N_6—PZH_4型的分V培养基配套对提高秈稻绿苗率效果较显著;经低温予处理30—48小时的秈稻花药的诱导效果比不处理高3～4倍;不同的秈稻杂交组合在花培中有较大的差异性。 The green plantlet rate of indica rice is controlled synthetically by all kinds of factors, the appropriate induction medium and differentiation medium are applied, the anther is pretreated at low temperature, etc. The synergistic effect of the synthetic factor is well exerted. Indica rice flower green seedling rate increased to 1.7% .General induction of cereal and M_3 type of sub-Ⅰ, sub-Ⅱ, sub-Ⅲ medium and N_6-PZH_4 type of sub-V medium to improve the efficiency of indica green plantlet rate than Significantly, the induction effect of indica anthers treated by hypothermia for 30-48 hours was 3 ~ 4 times higher than that of untreated ones. Different indica hybrid combinations had greater differences in flower culture.
