Abstract

Abstract: 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 Pennisetum sp. was the largest and that of I. cylindrica the smallest. The root tips and crossing numbers of Pennisetum sp. 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 Pennisetum sp.>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.

Key words: Benggang, Gramineae, herb plant, root architecture, principal component analysis
