外源激素对软枣猕猴桃扦插促根的影响
|
摘要
采用"龙成2号"软枣猕猴桃为研究试材,采用不同种类[生根粉(ABT)、6-苄氨基腺嘌呤(6-BA)、3-吲哚丁酸钾(3-IBA-K)、萘乙酸(NAA)]和不同浓度(100 mg/L、500 mg/L、1000 mg/L、1500mg/L)的外源激素对软枣猕猴桃硬枝进行了扦插生根处理,结果表明:采用生根粉(ABT)处理的软枣猕猴桃插条在成活株数、生根数量和根条长度上表现最佳,其中500 mg/L生根粉(ABT)处理的插条成活率最高,为89.3%,极显著高于CK(P<0.01),100 mg/L生根粉(ABT)处理的插条生根数量和根条长度最高,分别为10.8条和5.1 cm,均极显著高于CK(P<0.01),采用6-苄氨基腺嘌呤(6-BA)处理枝条效果最差,与其他3种外源激素差异显著,四种高浓度外源激素对扦插效果均不理想。
Taking "Heng you one number" Actinidia arguta as test material,Different kinds of exogenous hormones(100 mg/L,500 mg/L,1000 mg/L,1500 mg/L) and different concentrations(ABT、6-BA、3-IBA-K、NAA) were used to cut the hard branches of Actinidia arguta. The results showed that the cuttings treated with ABT had the best performances in the number of surviving plants, the number of rooting and the length of roots. The survival rate of cuttings treated with 500 mg/L ABT was 89.3%, which was significantly higher than CK(P<0.01) and 100 mg/L ABT(ABT) treatment. The number of roots and the length of roots were the highest,10.8 cm and 5.1 cm respectively,which were significantly higher than CK(P<0.01),The effect of 6-BA on branches was the worst. Compared with the other three kinds of exogenous hormones,four kinds of high concentration exogenous hormones had no ideal effect on cutting.
