浅橙红乳菇的解剖学性状及母种培养基筛选

Anatomy of Lactarius akahatsu Tanaka and Selection of Culture Medium

对在烟台市福山区野外采到的浅橙红乳菇的解剖学结构进行了研究,并进行了组织分离及培养基筛选。结果表明:浅橙红乳菇菌丝为土黄色,双核无锁状联合,子实体橙红色,无菌幕,菌柄中生,菌肉由球状胞和丝状菌丝缠绕构成。担子粗壮每个担子顶部着生4个担孢子,孢子球形表面有网格状突起,含油滴。菌丝在改良MMN培养基上生长较快速度达1.17mm/d,菌丝浓密,在PDA和棉籽壳培养基上长速分别为1.16和1.13mm/d,与改良MMN无显著差异但长势不如其浓密。

The anatomy of L,actarius akahatsu Tanaka that were collected in field of Fushan area Yantai city were studied. The mycelia of Lactarius akahatsu were cultivated by the method of tissue separation and the culture medium ofLactarius akahatsu were selected. The results showed that the mycelium of Lactarius akahatsu was khaki. The mycelium had two caryon without clamp connection. The color of fruit-body was salmon pink. The stipe of it was growth in centralpileus,without veil. The flesh of Lactarius akahatsu constituted by sphaerocyst and hyphae. The basidium of Lactarius akahatsu was strong, there were four basidiospore on the top of each basidium. The spore of Lactarius akahatsu wasspherical,the drop of oil were big. The optimal of mother culture medium was improved MMN. On improved MMN mycelium growth rate was 1. 17 mm/d,the mycelium was dense. The growth rate on PDA and cotton seed hull were 1.16and 1.13 mm/d. The there culture medium had no significant difference in growth rate.
