摘要:
以瑞丽山龙眼 Helicia shweliensis当年生半木质化健康枝条为扦插材料，开展了 3个因素 3个水平的正交试验，研究基质种类（河沙、泥炭、河沙 +泥炭 1∶1）、激素种类（生根粉 ABT1、细胞分裂素 CTK、萘乙酸 NAA)和激素浓度（ 100 mg·L-1，200 mg·L-1，500 mg·L-1）对插条生根率、根长、生根量的影响。结果表明，基质种类、激素种类和激素浓度都对瑞丽山龙眼扦插苗的生根率有显著影响（ P<0.05），其中，以河沙、浓度 100 mg·L-1 ABT1处理的生根率最佳，达到 65%；基质种类和激素种类是影响根长生长的主要因子，其中，以河沙和 CTK处理的根长生长效果最好，激素浓度对根长生长影响不显著；基质种类、激素浓度和激素种类都对生根量有显著影响（P<0.05），其中，以河沙 +泥炭、100 mg·L-1浓度 ABT1处理的生根量最佳。
Abstract:
In April 2017, current semi lignification branches from 20-30year Helicia shweliensis were selected for seedling cultivation by cuttings with orthogonal test of 3 levels 3 factors, namely substrate, hormone and concentration. During July 2017 and Feburay 2018, observations were carried out on rooting rate, root length and root number of cuttings. The results showed that different substrates, different hormones and concentrations had evident effect (P<0.05) on rooting rate of cuttings. Cuttings cultivated on the sand, with treatment of 100 mg·L-1 of ABT had the best rooting rate, of 65%. Substrate and hormone type were the main factors for root length of cuttings, Cuttings cultivated on sand, treated by cytokinin had the largest root length, concentration of hormones had no evident effect on root length. Substrate, hormone and concentration had evident effect (P<0.05) on root number. Cuttings cultivated on sand+peat, treated by 100 mg·L-1 of ABT had the largest number of root.
