摘要
以人工栽培的暗褐网柄牛肝菌(Phlebopus portentosus)为试材,观察其担孢子着生情况及细胞核数量,并以三轮杂交试验对其交配系统进行研究。结果表明:暗褐网柄牛肝菌每个担子上着生4个担孢子,每个担孢子内含有1个细胞核,53株单孢菌株按不同的交配型被分为4组,分别包含5、25、4、19个菌株,说明暗褐网柄牛肝菌属于四极性交配系统,交配型受双因子控制。
The insertion of basidiosporesand number of nuclei was observed inartificially cultivated Phlebopus portentosus,and the three-cycle mating tests were used to preliminarily study its mating system.The results showed that,each basidia produced 4basidiospores,and each basidiospore contained only one nucleus.53 monokaryonstrains were divided into four groups according to different mating types containing 5,25,4and 19 strains respectively.These results indicated that P.portentosushas atetrapolar heterothallism mating system under control of two genetic factors.
