【摘要】 对武夷山国家级自然保护区残遗与濒危树种南方铁杉植物群落历经了6年的调查,共采集了123种外生菌根,经显微与超显微技术鉴定了84种,这一结果是迄今为止已发表的,在同一树种中菌根类型最多的记录.它不仅证明了武夷山地区的菌物区系由于处于东西相连,南北贯通的位置上,而且从区系成分上据有温热两带俱全的特点,因而形成生物多样性,并从共生菌的角度再度揭示了物种协同进化的规律.更多还原

【Abstract】 Systematic investigation was made on ectomycorrhizae in the woods of a variety of Tsuga chinensis,tchekiangensis(Flous) Cheng,in Wuyishan Nature Reserve in the past six years.During that period,120 ectomycorrhiza samples were collected and 84 types identified by analysing their macro-micro-and ultrastructure.This is the first time that so many types of mycorrhiza in the forests of the species are reported on.This result has proved Wuyishan’s geographical position at the cross where a fungi growing area links the east and west,south and north.Thus the region owns the characteristics of both the temperate and the subtropical zone and it is thus such peculiarity whereby its biodiversity is created.Moreover,considering the results of this investigation in the regard of symbiosis between plants and fungi,their co-evolution is ascertained once more.更多还原
