大白菜腋芽扦插繁殖连续三年试验结果表明:NAA2000ppm 和 IBA 1500ppm+KT1500ppm 处理插穗均对生根有明显效果。扦插基质以粉煤灰+砂(1:1)效果最好。实践表明,腋芽扦插可提高母株繁殖系数2—3倍,在保存和扩繁珍贵种质,加快育种素材的纯化等方面有良好作用。
The axillary buds of Chinese cabbage cuttings for three consecutive years of trial results showed that: NAA2000ppm and IBA 1500ppm + KT1500ppm treatment cuttings on rooting have a significant effect. Cuttings to fly ash + sand (1: 1) the best. Practice shows that axillary bud cutting can increase the propagation coefficient of the mother plant 2-3 times, in the preservation and propagation of precious germplasm, and accelerate the purification of breeding material has a good effect.
