摘　　要：以香梨试管苗为实验材料,对均匀设计、配方筛选、营养成分分析得到的生根培养基进行形态和光合生理特征对比分析。测定和数据分析结果表明:香梨试管苗光合强度与生根率、展叶数、茎长等生长质量指标明显相关,认为不同生根培养基可明显改变试管苗的光自养能力,调配培养基组成也是提高试管苗光自养能力一项高效、实用的技术。In this teasearch, Pyrus sinkiangensis Yü was used as the experimental material, morphologic and photosynthetic traits of root planflets were compared and analyzed among optimized mediums which generated by uniform design, comparing and selecting approach, nutrition analysis. The result shows that the photcsynthsis is correlated to growth characteristics significiantly, such as the root rate, expanding leaves, the stem length and so on. This indicats that different root medium can influence the photosynthetic capability apparently, adjusting the component of basic medium is an efficient and banausic technique to improve photoautrophic growth of planflet.
