长汀县崩岗区8种禾本科植物根系构型特征
|
摘要
为探究崩岗区草本植物根系构型特征,以8种禾本科植物:白茅、金茅、五节芒、鹧鸪草、狗牙根、宽叶雀稗、巨菌草和香根草为研究对象,运用主成分分析法对其6个根系构型参数进行分析和综合评分。结果表明:试验草本根系平均直径为0.36~0.63mm;金茅、五节芒、鹧鸪草、宽叶雀稗和香根草总根长无显著差异;总根表面积、总根体积、根尖数和交叉数均不同,巨菌草的总根表面积最大,白茅的最小,巨菌草的根尖数和交叉数均最大。根系构型的主要影响因子是平均直径、总根表面积和总根体积。8种植物根系综合得分依次为:巨菌草>宽叶雀稗>金茅>五节芒>香根草>鹧鸪草>狗牙根>白茅。研究成果可为崩岗治理中草本植物的筛选、配置和推广提供科学依据。
In order to explore the root architecture of herbaceous plants in the Benggang area,eight Gramineae species were studied(Imperata cylindrica,Eulalia speciosa,Miscanthus floridulus,Eriachne pallescens,Cynodon dactylon,Paspalum wettsteinii,Pennisetum sp.and Vetiveria zizanioides).Six root architecture parameters were analyzed and comprehensively evaluated using principal component analysis.The results showed that the average diameter of the tested herbaceous roots was between 0.36 and 0.63 mm.There were no significant differences in the total root length of E.speciosa,M.floridulus,E.pallescens,P.wettsteinii and V.zizanioides.The total root surface area,total root volume,root tip numbers and crossing numbers varied by plant species.The total root surface area of Pennisetumsp.was the largest and that of I.cylindricathe smallest.The root tips and crossing numbers of Pennisetumsp.were also the largest.Average diameter,total root surface area and total root volume were the main factors influencing root architecture.The composite score order of the eight species' roots was Pennisetumsp.>P.wettsteinii>E.speciosa>M.floridulus>V.zizanioides>E.pallescens>C.dactylon>I.cylindrica.These results help to provide a scientific basis for the screening,allocating and popularizing of herbaceous plants for the control of erosion.
