22株金针菇菌株的农艺性状比较

Agronomic Characteristics and Their Correlations with Yield of 22 Strains of Flammulina velutipes

对22株金针菇菌株进行农艺性状对比试验,并对菌株单袋均产量与菌柄长度、菌盖大小、菌盖厚度进行回归分析。结果表明F0006、F0016＋1、F0111、F0148、F0154菌株为白色,其余为黄色或浅黄色;其中黄色和浅黄色菌株产量比大部分白色菌株要高,且现蕾天数较短,在16-28d,白色菌株除F0016＋1号外现蕾天数均在50d以上,F0016＋1白色菌株,产量高,现蕾短,菌柄较长,菌盖很厚,菌盖大小适中且不易开伞,性状较好,商品价值高;其中产量与菌柄长度有正相关性,与菌盖大小和厚度没有相关性。

Agronomic characteristics, e. g. , stipe length, cap size, and cap thickness, as well as their correlations with the product yield of 22 strains of Flamrnulina velutipes were studied. The results showed that the color of the fruiting bodies of F0006, F0016＋1, F0111, F0148, and F0154 was white, while the others were yellow or light yellow. In general, the yellow and pale yellow mushrooms had a higher yield and a shorter squaring time （i. e. , 16 -28 days vs. 50＋ days for most of the white strains, except F0016＋1） than their white counterparts. The white F0016＋1, showing a high yield, short squaring time, long stipe, very thick cap with regular size, and delayed parachuting, was considered a strain with desirable traits and high commercial value. It was found that the stipe length, not the size nor cap thickness, correlated positively with the mushroom yield.
