摘要
激素和扦插基质是影响扦插生根的重要因素。本试验研究不同激素和扦插基质对黄花远志扦插生根的影响。试验开始于2004年4月15日,7月26日出苗,并统计生根情况。结果表明:插条的生根率与激素浓度有关,生根质量与激素的种类有关;插条在400mg·L-1吲哚丁酸+400mg·L-1萘乙酸、800mg/L吲哚丁酸、800mg·L-1萘乙酸溶液中浸泡10min,生根效果较好,生根率分别达到34.0%、29 3%、28 8%;蛭石+珍珠岩、泥炭土+河沙两种扦插基质相比,生根效果以泥炭土+河沙为佳。
Hormones and substrates are important factors on cutting rooting.Tests and studies of different hormones and substrates on cutting rooting of Polygala arillata var.were made in this paper.The study began on April 15,2004,and finished on July 26,whose data were obtained.The results showed that the rooting ratio was related to the concentration of hormones while the rooting quality was related to the kind of hormones.And rooting ratios were 34.0%,29.3% and 28.8% respectively after cuttings were sopped in different hormones for ten minutes including 400 mg·L^(-1) IBA+400 mg·L^(-1) NAA,800 mg·L^(-1) IBA,800 mg·L^(-1) NAA.Rooting effect of cuttings in substrate of peat+river sand was better than in vermiculete+perlite.
