Difference in Fiber Morphology and Chemical Composition of Phyllostachys heterocycla cv.pubescens from Plantation of Different Altitudes
摘要
Abstract
Fiber morphology and chemical composition of Phyllostachys heterocycla ev.pubescens planta tion from different altitudes were determined and analyzed, and the variation regularities were revealed.The results showed that fiber length, the ratio of length to width and the ratio of long fiber of P.hetero cycla cv.pubescens culm growing in the altitude of 300 m were bigger than those in the altitude of 600 m and 900 m.Altitude had extremely significant effects on fiber morphology of P.heter ocycla cv.pubescens Hot water extractive content, benzene-ethanol extractive content, Klason lignin content and ash content increased with the increase of altitude, while 1％ NaOH extractive content, cellulose content and pH value decreased.P.heterocycla cv.pubescens growing in the altitude of 300 m was optimum for pulpwood.关键词
