镜泊湖熔岩台地17种草本植物1级根形态性状研究
Study on the Morphological Characteristics of Grade 1 Roots of 17 Herbaceous Plants on the Lava Plateau of Jingbo Lake
摘要
Abstract
In order to understand the root functional traits characterizion of the herbaceous plants and to reveal the root adaptive mechanisms and strategies of the herbaceous with different life histories in Jingpo Lake lava plateau.In this study,we analyzed four morphological traits:root diameter,root tissue density,specific root length and specific surface area of 17 herbaceous plants from the Jingpo Lake lava plateau in Mudanjiang,and explored the differences in roots morphological traits of different life histories(11 annuals and 6 perennials).The results showed that the annual plant Amethystea caerulea L.and the perennial plant Viola variegata Fisch ex Link first order roots have the largest root diameter,root tissue density and specific surface area,Cnidium monnieri L.and Aster pekinensis(Hance)Kitag first order roots have the largest specific root lengths in Jingpo Lake lava plateau.The perennial plants first order roots root diameter was significantly larger than that of annual plants(P＜0.05),the specific root length of the an-nual plants first order roots was significantly larger than that of perennial plants(P＜0.05),and the root tissue den-sity and specific surface area of the first order roots were not significant difference among annual and perennial plants.关键词
