摘　　要：选择黄条金刚竹、箬竹、鹅毛竹和白纹椎谷笹的幼苗为研究对象,研究不同土壤水分条件下地被竹内源激素含量的动态变化。试验结果表明,不同地被竹竹种内源激素含量随着浇灌间隔时间的变化。叶的激素含量容易受到浇灌间隔时间的影响,而地下部分的根与地下茎变化趋势较为一致。鹅毛竹的叶与根中的内源脱落酸的含量明显高于其他竹种。不同地被竹竹种对不同土壤水分条件的适应性不同。With seedlings of Pleioblastus kongosanensis f.aureostriaus,Indocalamus tessellatus,Shibataea chinensis and Sasaella glabra,the dynamic changes of endogenous hormone in different bamboo plants are studied under the conditions of different oil water content.Results indicate that the content of endogenous hormones changes with irrigation time span,while the endogenous hormonecontent in leaves is affected by irrigation interval.The varied trend of roots is similar to that of rhizomes.The abscisic acid content in leaves and roots of Shibataea chinensis is higher than that of other bamboo species.Different dwarf bamboo species show different adaptability under different irrigation intervals.
