ABT生根粉浸根造林应用研究报告 总被引:1,自引:0,他引:1
采用3号ABT生根粉,共设13个处理浸泡供造林苗木根系。结果表明,浓度35×10-6~75×10-6,浸根50~60min,对马尾松造林成活率和当年抽高有极显著效果。浓度50×10-6~75×10-6,浸根40min对杉木当年抽高影响达极显著水平,但对成活率的影响不显著。 相似文献

几种生根剂对金银忍冬嫩枝扦插育苗作用的试验初报 总被引:2,自引:0,他引:2
用IBA、NAA、ABT1、IBA+NAA四种生根剂,分别以不同浓度,不同浸泡时间处理金银忍冬嫩枝插穗进行扦插育苗试验,结果表明:用IBA 1000×10^-6、处理2s、生根率最高为69.4%;用NAA 1000×10^-6、处理时间2s、生根率最高为90%;用ABT1 200×10^-6、处理时间2h、生根率最高为80.2%;用NAA 100×10^-6+IBA 50×10^6、处理2h、生根率90%或NAA 50×10^-6+IBA 100×10^-6、处理12h、生根率90%,用清水处理2h,生根率70.4%,表明用外源激素处理能够提高金银忍冬嫩枝扦插的生根率,增加不定根数量。从上面的方差分析结果综合生根率和生根性状的各项指标,如果选择一种激素,选择NAA 100×10^-6+IBA50×10^-6、处理2h、生根率90%,效果最为理想。 相似文献

Vegetative propagation of Aesculus indica through stem cuttings treated with plant growth regulators 总被引:1,自引:0,他引:1
Cuttage propagation of Aesculus indica was tested by treatments with different concentrations of indole-3-acetic acid (IAA) @ 2000, 4000 (ppm), indolebutyric acid (IBA) @ 2000, 4000 (ppm) and naphthlcetic acid (NAA) @ 2000, 4000 (ppm) in dry formulation in the Forest Nursery, Faculty of Forestry, SKUAST-K, Shalimar. The cuttings treated with IBA @ 4000 ppm and IBA @ 2000 ppm had a sprouting rate of 75% and 50%, respectively, which was significantly higher than that of control and other treatments. The highest rooting rate (50%) was recorded in the cuttings with the application of IBA @ 4000 ppm. The cuttings treated with IBA @ 2000 ppm had 25% rooting rate. All other treatments along with control (talc powder) failed to induce rooting. It was concluded that IBA @ 4000 ppm was a better-applied concentration for vegetative propagation of A. indica under Kashmir conditions. 相似文献
