4种悬钩子属植物的繁育方式研究

摘要

选取山莓(Rubus corchori folius L.f.)、插田泡(R.coreanus Miq.)、光滑悬钩子(R.tsangii Merr.)、茅莓(R.parvi folius L.)4种野生悬钩子健壮植株为材料,通过扦插、分株和根蘖、压条等试验,研究其最适繁育方式.结果表明,4种悬钩子的木质化结构不充分,扦插生根较为困难;山莓可通过分株和根蘖的方式繁殖;插田泡可通过分株、根蘖、压条的方式进行繁殖;光滑悬钩子主要通过分株和根蘖的方式繁殖;茅莓可通过分株、根蘖和压条的方式繁殖.%In this paper, robust plants of four species of Rubus, R. corchorifolius L. f. , R. coreanus Miq. , R. tsangii Merr. and R. parvifolius L. , were used as materials. After the experiments of cutting propagation, division propagation, root sprout propagation, and layering propagation, the optimum reproductive modes were selected. The results showed that, low lignifica-tion levels of four species of Rubus lead to difficult rooting through cutting propagation; R. corchori folius L. f. and R. tsangii Merr. can be breed by division propagation and root sprout propagation; division propagation, root sprout propagation, layering propagation applied to the breeding of R. coreanus Miq. and R. parvifolius L.
