灰树花品系的初步研究

Study on the Strains of Grifola frondosa (Fr)S F Gray

征集国内外１７个灰树花品系，通过室内外栽培试验结果，从中筛选出有代表性的优质菌株：ＧＦ１７为中温型，子实体形成、成熟温度１７～２６℃，最适温度２１～２２℃，早熟，子实体色泽乳白色或灰白色，单朵平均鲜重１４３ｇ，结实率超过９５％；ＧＦ５为中偏低温型，子实体形成、成熟温度１６～２０℃，最适温度１８℃，中熟，色泽黑色，单朵平均鲜重１１６．５ｇ，结实率９０％以上；ＧＦ１１、ＧＦ６为低温型，子实体形成、成熟温度１４～１９℃，最适温度１６℃，晚熟，色泽灰黑色，单朵平均鲜重分别为１５１．５ｇ和１１９．５ｇ，结实率超过８５％。发现不同品系之间各氨基酸含量存在差异。

Seventeen strains of Grifola frondosa were collected from China and foreign countries Indoor and outdoor experiments showed that,GF 17 belonged to middle temperatural type,its fruitbodies formed and developed at 17～26℃,the optimum temperature was 21～22℃;early maturity,white colour,the average fresh weight of single fruitbody was 143.5g,bearing rate reached 95% or more;GF 5 was mid low temperatural type,grew and developed at 16～20℃,optimum was 18℃,middle maturity,black colour,fresh single fruitbody weighted 116 5 g,bearing rate was more than 90%.GF 11 and GF 6 were low temperatural type,grew at 14～19℃,the optimum was 16℃,late maturity,grey colour,average fruitbody weights were 151 5 and 119 5 respectively,bearing rate reached 85% or more.The analysis results showed that various GF strains differ in their amino acid contents.The illumination intensity was an important factor for the colour forming and quality of fruitbodies.
