以赤皮青冈(Cyclobalanopsis gilva)插穗为试验材料,通过扦插育苗试验探讨了不同浓度、不同类型生长调节剂作浸穗处理对赤皮青冈扦插苗生根率、平均根长、平均生根数的影响.研究表明:(1)同种条件下,与清水浸穗处理的对照相比,以GGR、IBA、IAA3种生长调节剂不同浓度对赤皮青冈的生根率、平均根长、平均生根数具有明显的促进作用.(2)3种生长调节剂类型处理的赤皮青冈插穗的生根率、平均根长、平均生根数3个指标均在100～ 300 mg/L时达到峰值,表明3种生长调节剂对赤皮青冈浸穗处理的最适浓度在200 mg/L左右.其中200 mg/L GGR效果最好,生根率68.4％,平均根长3.52 cm;平均生根数5.55条;IBA与IAA效果相...

Taking Cyclobalanopsis gilva scions as experiment material,the effect of soaking treatments by growth regulators with different concentrations and types on rooting rate,average root length and average rooting number of Cyclobalanopsis gilva cuttings was studied. The results showed that under the same condition,compared with the soaking in clean water,the effect of soaking in three growth regulators including GGR,IBA and IAA with different concentrations on rooting rate,average root length and average root number was obvious,all of which reached...
