| 摘 要： | 目的]探究影响杏鲍菇产量的几个主要农艺性状与单菇鲜重之间的关系。方法]对影响杏鲍菇单菇产量的主要农艺性状菌盖直径、茵柄直径、茵柄长度、菌盖厚度、干物质含量与单菇鲜重之间的关系进行相关性分析及通径分析，最后通过多元逐步回归分析。结果]得到了单菇鲜重（Y）与茵盖直径（X1）、菌柄长度（X3）以及干物质含量（墨）之间的最优回归模型：Y=-2．496＋2．026X1＋0．486X3＋5．124X5。结论】为杏鲍菇遗传育种以及增产增收奠定了基础。

| Abstract: | Objective] The relationship between several major agronomic traits and fresh weight of Pleurotus mushroom was explored.Method] The correlation analysis and path analysis between the fresh weight of single mushroom and relative factor affecting the yield such as the diameter and thickness of mushroom cap,the diameter and length of mushroom stipe,the content of dry matter were conducted,respectively,and then,the multiple stepwise regression analysis was done.Results] The optimal regression model: Y=-2.496+... |
