摘要
砧木直接影响苹果树的生长、结果、抗逆能力和寿命。近年来随着苹果矮化密植栽培的迅速发展,矮化砧木更显示了特殊作用。以往生产所用苹果砧木多用种子繁殖,长出的植株分离严重,造成嫁接品种后的苹果树生长、结果表现很不一致。
The growing points of axillary buds of apple rootstocks(eight strains aud species)were cultured in vitro.A modified MS medium was used for the proliferation and rooting.The highest rate of proliferation for M4 was 51.4%,and the rooting rate was 71.4—83.3%.Through sand culture,a survival at the rate of seedlings of 38.4%was obtained.Through soil culture over 5—10 mouths the seedlings were suitable for grafting.881 seedlings were obtained from the growing points of the bud of M4 apple rootstock by soil culture within two years.It speeds up significantly the process of proliferation of the seedlings of apple rootstock and presents a prospect of proliferation of seedlings in factory.
