摘    要:比较了生长于贫营养的大溪水库(江苏)和富营养的太湖梅梁湾苦草的根系形态性状特征和叶片与匍匐苇的解剖结构差异,结果表明:生长于贫营养状态的大溪水库中的苦草根系形态性状的总根长、表面积、截面积、体积、平均直径和总分叉数等特征参数都显著高于生长于富营养状态的太湖梅梁湾的苦草.大溪水库的苦草叶片表面光洁,受附着生物影响明显较来...

关 键 词:苦草  营养状态  解剖结构  大溪水库  太湖梅梁湾

Abstract:Vallisneria natans from oligotrophic water body(Daxi Reservoir,Jiangsu) and eutrophic bay of Lake Taihu(Meiliang Bay) was studied to observe morphological characteristics of roots and anatomical structures of leaves and stolons.The results showed that root morphological characteristics,including total root length,root surface area,projected root area,total root volume,average root diameter,and total forks of V.natans from oligotrophic Daxi Reservoir,were significantly higher than that of V.natans from eutro...
Keywords:Vallisneria natans  trophic level  anatomical structure  Daxi Reservoir  Lake Taihu  Meiliang Bay
