分蘖数和栽培基质对金钗石斛茎叶生长的影响
Effects of Tiller Number, Cultivation Substrates on the Growth of Stems and Leaves of Dendrobium nobile
摘要
Abstract
Objective] Effects of tiller number, cultivation substrates on the growth of stems and leaves of Dendrobium nobile were studied, the suitable cultivation substrates and tiller number were discussed, so as to provide a scientific basis for artificial cultivation of Dendrobium nobile.[ Method] Taking Guizhou Chishui annual Dendrobium nobile tissue culture seedlings as materials, under artificial potted conditions, 3 kinds of tiller number, 4 kinds of culture mediums, cultivating for 30, 60, 90,150, 360 d, the growth of stem, stem diameter, leaf number, leaf SPAD value, stem fresh weight, dry weight, branch breaking rate were studied.[ Result] The sawdust is the best culturing medium. When tiller number is 2, cultivating for 150, 360 d in 4 cultivation matrices, the growth of stem is 7.20, 5.20, 3.20, 1.00, 8.40, 6.80, 6.25, 2.65 cm, were the highest.The growth of stem diameter and tiller number showed no difference.The amount of leaves reduced lowest in the sawdust substrate, leaf SPAD value decreased with time growing and leaf reducing.There were significant differences of leaf SPAD value among different tiller number,various matrices cultivating for 150, 360 d.[Conclusion] After seedling cultivation for 360 d of Dendrobium nobile with different tiller number, the growth of stem, stem diameter, branch breaking rate had no correlation with tiller number, while showed significant correlation with stem fresh weight, dry weight.关键词
