植物生长调节剂对‘长富—2’苹果离体繁殖的效果表明:(1)增殖和生长以BA 1.0—1.5mg/L、IBA 0.5mg/L 较为适宜,高浓度的 BA 和 IAB 易产生玻璃苗和其它异常现象;赤霉素促进新梢的生长.浓度为3.0mg/L 时对增殖有促进作用.(2)三十烷醇对增殖和生长具有显著的效应.(3)不定根的诱导以附加1.0—3.0mg/L IAA 或0.5mg/L IBA 较好.(4)培养基中附加 PP333可以促进根的形成。提高试管苗的移栽成活率.(5)转移培养对生根率和生根数目无显著影响,但有利于试管苗的移栽.
The results showed that: (1) BA 1.0-1.5mg / L and IBA 0.5mg / L were more suitable for proliferation and growth, and higher concentrations of BA and IAB were more likely to occur Glass seedling and other abnormal phenomena; gibberellin promoted the growth of new shoots, promoted the proliferation when the concentration was 3.0mg / L, (2) triacontanol had a significant effect on proliferation and growth. (3) Adventitious roots Induction with additional 1.0-3.0 mg / L IAA or 0.5 mg / L IBA is better. (4) Additional PP333 in the medium can promote root formation. (5) The transplanting culture had no significant effect on the rooting rate and the number of rooting, but was beneficial to the transplanting of the test tube seedlings.
