摘　　要：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 ofA. indica under Kashmir conditions.采用不同浓度的吲哚乙酸（IAA），@2000，4000（ppm）、吲哚丁酸（IBA），@2000，4000（ppm）和萘乙酸（NAA），@2000，4000（ppm）生长素对印度夏尔美林业苗圃的印度七叶树（Aesculus indica）枝插条进行处理。结果表明，IBA@4000ppm和IBA@2000ppm处理扦插苗叶芽萌发率分别为75％和50％，明显高于对照及其它两种生长调节剂处理。IBA@4000ppm和IBA@2000ppm处理的扦插苗生根率分别为50％和25％，而其它处理则扦插苗不生根。说明IBA@4000ppm是当地印度七叶树扦插繁摹较适合的植物生长素和施用浓度。图2表2参13。
