以榆黄蘑(Pleurotus citrinopileatus)10个菌株为试验材料,以40%的黑木耳菌糠作为栽培基质,通过观测菌丝生长速度、发菌速度、菌盖颜色、菌盖大小、菌盖厚度、产量等农艺性状,评价不同菌株的生物学特性;同时以各不同的农艺性状为基础,计算不同性状内的变异系数,并对菌株进行聚类分析。研究结果表明:榆黄蘑10个菌株9个农艺性状之间存在不同程度的变异,变异系数7%~27%。其中变异系数最大的是产量性状(27%),变异系数最小的是菌柄长度性状(7%)。在欧氏距离7.08处,10个菌株被分为3个类群,聚类结果与菌株的生育期有一定的关系。综合评价说明,韩CB6(韩引品种)、榆黄蘑2013较适合在牡丹江地区推广栽培。
Ten strains of Pleurotus citrinopileatus were used as test materials and 40% of Aralia mucilaginosus was used as substrate for culture. The growth of mycelia, the speed of growth, the color of cap, the size of cap, the thickness of cap, Yield and other agronomic traits to evaluate the biological characteristics of different strains. At the same time, based on different agronomic traits, the coefficient of variation of different traits was calculated and the strains were clustered. The results showed that there were different degrees of variation among nine agronomic traits in 10 strains of Ulmus pumila, with a coefficient of variation of 7% -27%. Among them, the biggest variation coefficient was the yield trait (27%), and the smallest variation coefficient was the pedicle length trait (7%). At Euclidean distance 7.08, 10 strains were divided into 3 groups, and the clustering results had some relationship with the growth period of the strains. Comprehensive evaluation shows that the Korean CB6 (Korean cited varieties), yellow mushroom 2013 more suitable for promotion and cultivation in Mudanjiang.
