摘要/Abstract

摘要：

为调查崂山茶区土壤中丛枝菌根(AM)真菌资源的分布状况, 于2007年9月从青岛崂山茶区12个茶园采集茶树(Camellia sinensis)根围土样, 采用湿筛倾注-蔗糖离心法分离AM真菌, 测定其物种丰度、频度、孢子密度、相对多度、重要值、多样性指数等。共分离到AM真菌3属22种, 无梗囊霉属(Acaulospora)出现的频度最高, 其次是球囊霉属(Glomus)。AM真菌孢子密度以晓望村茶园最高, 高家村茶园最低; 种丰度以常家村茶园最高; 常家村茶园和万来客茶园的Shannon-Wiener指数显著高于其他茶园。光壁无梗囊霉(Acaulospora laevis)是北崂茶厂、万里江茶园、樱山春茶园、万里江有机茶园、常家村茶园和桑园村茶园的优势种; 波状无梗囊霉(Acaulospora undulata)为万里江有机茶园和万来客茶园的优势种; 隐球囊霉(Glomus occultum)为樱山春茶园、晓望村茶园和万来客茶园的优势种。应用典型相关分析(CCA)对环境因子与崂山茶区AM真菌群落组成的关系进行了分析, 各因子的影响大小依次为: 土壤速效磷含量>土壤有机质含量>种植年限>土壤碱解氮含量>土壤pH值>土壤速效钾含量。

关键词: 菌根真菌, 茶园, 丰度, 频度, 孢子密度, CCA 分析

Abstract

To determine the diversity of arbuscular mycorrhizal (AM) fungi in the rhizosphere of tea plant (Camellia sinensis) in Laoshan region, Shandong Province, we selected and sampled 12 representative tea gardens. Soil samples were collected from these gardens in September 2007. Spores of AM fungi were identified to reveal the species richness, frequency, spore density, relative abundance, importance value and Shannon-Wiener indices of AM fungi. Species diversity and composition of AM fungal community were also compared among the 12 tea gardens. A total of 22 species belonging to three genera were identified according to the morphological characteristics of the spores isolated from soil samples collected using wet-sieving techniques. The relative abundance of the genus Acaulosporawas the highest, followed by Glomus. Soil samples from Xiaowang Village Tea Garden showed the highest spore density, while Gaojia Village soils were the lowest. Species richness in soil samples from Changjiacun Village and Sangyuan Village Tea Garden was significantly higher than that in other tea gardens. Species diversity was highest in the Changjiacun Village Tea Garden. Acaulospora laeviswas the dominant species in Beilao Tea Garden, Wanglijiang Tea Garden, Yingshanchun Tea Garden, Wanlijiang Organic Tea Garden, Changjia Village, and Sangyuan Village Tea Garden, while Acaulospora undulata was the most common species in Gaojiacun Village and Wanlaike Tea Garden. Glomus occultum occurred most frequently in Yingshanchun Tea Garden, Xiaowang Village and Wanlaike Tea Garden. Relationships between environmental factors and AM fungi spore density in the Laoshan Tea region were determined using Canonical Correspondence Analysis, and their relative degree of impact on density was as follows: available phosphorus content>soil organic matter content>tree age>soil available nitrogen content>soil pH>soil available potassium content.

Key words: mycorrhizal fungi, tea gardens, species richness, frequency, spore density, CCA analysis
