为了研究不同贮藏温度对青花菜贮藏期间幼苗质量以及定植后幼苗生长发育的影响，以优秀为试材，分别在11、16、21℃条件下贮藏0、2、4、6 d，筛选出与定植后幼苗心叶生长速度相关的形态指标。结果表明：贮藏温度为11℃的处理幼苗形态指标保持良好，第1片真叶单位面积叶绿素含量相对较高，定植后幼苗心叶生长速度较快。相关性分析结果表明，贮藏期幼苗壮苗指数与定植后植株生长恢复能力的相关系数最高，可作为评价青花菜幼苗贮藏质量的一项指标；通径分析结果表明，复合指标“第1片真叶单位面积叶绿素含量、壮苗指数、比叶重”能够很好地反映青花菜幼苗短期贮藏后的生长恢复能力。

To study the effect of different storage temperatures on broccoli (Brassica oleraceaL.var. italica Plenck)seedling quality,growth and development after fix planting,this paper screened the related morphological indexes of seedling new heart leaf growth rate after planting,taking‘good’as test material to evaluate the quality of broccoli seedlings under temperature 11,16,21 ℃ and stored for 0,2,4,6 days,respectively.The results showed that in the storage temperature of 11 ℃,seedling’s morphanological index maintained in good shape,the chlorophyll content per unit area was relatively higher,and the seedling new heart leaf grew rapidly.The correlation analysis results showed that the sound seedling index and plant recovery ability after fix planting during storage period had the highest correlation coefficient.The sound seedling index could be an indicator for evaluating the storage quality of the broccoli seedling.The path analysis results showed that composite indexes of chlorophyll content per unit area,sound seedling index,specific leaf weight could well reflect the growth recovery ability of broccoli seedling after short-term storage.
