摘要: 为了探讨外源植物生长调节剂对石蒜属植物鳞茎生长的影响，以盆栽石蒜(Lycoris radiata )为研究材料，浇施不同浓度的6-BA，在不同日期后测定土壤和石蒜鳞茎中6-BA的含量。结果表明土壤中6-BA含量无显著性差异(不同浓度P = 0.290、不同日期P = 0.224)，但鳞茎中6-BA含量差异显著，其中以施用后的第4天鳞茎中6-BA含量达到最大(312.5 mg/kg)，随后不断减少；鳞茎中6-BA含量与施用浓度有关，呈施用浓度越高鳞茎中含量越高的倾向；叶数量和根数量无显著性差异；鳞茎湿重无显著差异，但湿重比有显著差异；因此，通过施用6-BA，本研究未能促进石蒜鳞茎生长。
Abstract: In order to investigate the effects of exogenous plant growth regulators on the growth of Lycoris radiata bulbs, different concentrations of 6-BA were poured to potted Lycoris radiata, and the content of 6-BA in soil and Lycoris radiata bulbs was tested after different dates. The results showed that there was no significant difference in the content of 6-BA in soil (P = 0.290 at 6-BA different concentrations and P = 0.224 at different days), but the contents of 6-BA in bulbs was significant. The con-tent of 6-BA in bulbs reached the maximum (312.5 mg/kg) on the 4th day after pouring, and then decreased continuously. The content of 6-BA in bulbs was related to the concentration of poured 6-BA, which tended to be higher in bulbs with higher concentration of poured 6-BA. There was no significant difference in the number of leaves, roots and bulbs wet weight, while the wet weight ratio had significant difference. Therefore, 6-BA failed to promote the bulb growth of Lycoris radiata.
