近年来,不仅能从油菜的花药诱导形成花粉植株(上海植生所,1973;广东植物所,1975),而且能从油菜的花丝、花瓣、花托、子房及幼嫩的花序轴切段诱导成苗(上海植生所,1977)。我们通过对油菜的高脚茎段分化培养,同样能直接形成苗。切段分化成苗的频率在80%以上,每块切段芽数高的达10～20个。材料和方法油菜(23号)在育苗期间,因密度过大和气温较
In recent years, not only pollen plants can be induced from anthers of rapeseed (Shanghai Institute of Plant Biology, 1973; Guangdong Institute of Botany, 1975), but also can be induced from cuttings of rape florets, petals, torus, ovary and young inflorescences Miao (Shanghai Plantation, 1977). We through the high stem of rape differentiation culture, the same can be directly formed seedlings. Cut into segments of the frequency of seedlings in more than 80%, the number of buds per cut high up to 10 to 20. Materials and methods Rape (No. 23) During nursery, due to over-density and temperature
