【中文摘要】 研究结果表明，无论是香菇生料菌砖栽培，还是金针菇熟料袋栽，菌种世代的多少对产量均无明显的影响，这可能是由于菌种通过无性繁殖，遗传性变异甚小之故；研究结果还表明。会针菇菌竺生长的速度似平有随着菌种世代的增多而加快的趋势，这究竟是由于低代菌种自琼脂培养基侈接到以杂本屑、棉籽壳等为主要原料的粗质培养基上的时间较短、适应酶的活性较弱，分解、利用高分子化合物的能力较差，故菌丝生长速度较为缓慢？还是由于其他原因造成的？有待进一步探讨。
【英文摘要】 Results of the present study show that no influences were perceptible on the yields caused by different generation of the spawn either in raw-material-brick culture of Lenf-inus edodes of in cooked-material-bag culture of Flammulina velutipes. This may be due to the inheritable variation being very small in the vegetative propagation. The results also indicate that the Flammulina velutipes mycelium growth speed almost tends to increase wlth increase of the generation level.It remains to be approached whether it is due to the fact that the low-generation spatvn,inoculated earlier from the agar medium to the coarse mediujm of wood scraps and cottonseed hulls with other materials, is comparati-vely weak in adaptive enzyme activity and less capable of dissolving and utilizing high-molecule compounds hence the mycelium growth becomes slower,or it is due to other facts.
