9个粳稻品种未传粉子房的培养试验表明,品种间愈伤组织的诱导率、分化率均存在差异。早粳优于晚梗。抽穗期早的品种具有较高的成苗率。外源激素对诱导分化具有十分重要的作用。MCPA(2-甲基-4-氯苯氧乙酸)优于2.4-D。
The cultivation experiments of non-pollination ovary in 9 japonica varieties showed that the callus induction rate and differentiation rate differed among cultivars. Early japonica is better than late stem. Early heading varieties have higher seedling rate. Exogenous hormones on the induction of differentiation has a very important role. MCPA (2-methyl-4-chlorophenoxyacetate) is superior to 2.4-D.
