不同生长激素对金钟花嫩枝扦插的影响

Effects of Plant Growth Hormone on Forsythia viridissima Shoot Cutting

以金钟花插穗为试材,研究3种生长激素的不同浓度溶液速蘸处理对金钟虚化插穗的成活率、生根数量和质量的影响。结果表明:萘乙酸3 000、5 000mg/L以及吲哚乙酸5 000mg/L处理的插穗成活率在95%以上,其中萘乙酸3 000mg/L处理的成活率为100%,平均生根量为27.0783条。

The cuttages of Forsythia viridissima were used as materials, the survival rate, the quality and quantity of the root of cuttage with three kinds of growth hormones under different concentrations were survied. The results showed that treated with NAA of 3 000 and 5 000 mg/L and indole acetic acid of 5 000 mg/L,the survival rate reached 95% above, among which treated with 3 000 mg/L NAA, the survival rate reached 100% and its average quantity of root was 27. 0783.
