Growth and Spatial Distribution Characteristics of Rhus javanica Populations Sowed on Cut-Slopes - Focusing on the Dae-Ji Mountain Case Study -

Abstract

This study was to evaluate the growth and spatial distribution characteristics of Rhus javanica population. The study was conducted between 2015 January and July at the cut-slope revegetation site in Dae-Ji Mountain. Seeds of native species were sowed on the disturbed cut-slope in 2002. There were 119 vascular plant species 55 families and 94 genera on the cut-slope. Compositae, Rosaceae, and Leguminosae plants were dominant species, which are pioneer species in dry and barren site.Canopy of trees covered 44.1% total area, which was 8.3% increase from 2008. Rhus javanica, main species, dominated all DBH classes except DBH >24cm. Albizzia julibrissin showed high frequency in the 6∼17cm DBH class and Salix koreensis was abundant at >12cm. Elaeagnus umbellata, Corylus heterophylla var. heterophylla, Alnus sibirica, and Acer pictum were not observed. Rhus javanica population was the most frequently observed on the south facing cut-slope. The average DBH of Rhus javanica was 7.3(±3.7)cm and the average height of them was 5.2(±1.7)m. Annual average DBH growth was 7.9mm/yr and the maximum growth(12.0mm/yr) was the 3 rd year. It decreased after 6 th

The Complete Chloroplast Genome Sequence and Intra-Species Diversity of Rhus chinensis

“…In addition, R. chinensis is used for ecological restoration (Nam et al 2004;Lim and Oh 2015). Due to its wide utility, it is necessary to explore this plant for genetic diversity and marker development to prevent false trading …”

“…It contains various pharmacologically active constituents and insect-induced galls, which have been used for medicinal purposes (Min and Barfod 2008;Djakpo and Yao 2010). In addition, R. chinensis is used as revegetation plant for ecological restoration owing to its cold tolerance and easy multiplication by both seed and clonal propagation (Nam et al 2004;Lim and Oh 2015). The diverse utilization of this shrub led to international seed trading which in turn resulted in contamination and destruction of endemic population of R. chinensis.…”

Variation among the Complete Chloroplast Genomes of the Sumac Species Rhus chinensis: Reannotation and Comparative Analysis

“…R. chinensis is a common deciduous sumac tree that is widely distributed in Asia, including China, India, Vietnam, Korea, and Japan [ 4 ]. This species is an important medicinal plant containing various pharmacologically active constituents, which have been used for medicinal purposes such as anticancer, antiviral, antimicrobial, and anti-inflammatory as well as being used as a revegetation plant for ecological restoration due to its cold tolerance and easy multiplication [ 5 , 6 , 7 , 8 ]. In particular, as the primary host plant of several species of Chinese sumac aphids, R. chinensis hosted the aphids which induced galls, which are a source of traditional Chinese medicine [ 9 ].…”
