兰属(Cymbidium)植物茎的初探

PRELIMINARY STUDY ON STEMS OF CYMBIDIUM PLANTS

在兰花栽培中对兰属(Cymbidium)几种植物的茎作了初步观察,加深了对兰茎的认识,认为兰茎的形态及其生物学特性具有重要的意义。观察的种类 一、长苞组(Sect.Maxillarianthe Schltr.) 1.春兰(Cymbidium goeringii(Rchb.f.)Rchb.f. 2.春剑(变种)C.goeringii(Rchb.f.)Rchb.f.var.longibracteatum(Y.S.Wu et S.C.Chen)Y.S.Wu et S.C.Chen 3.峨眉春蕙(变种)C.faberi Rolfe var.omeiense(Y.S.Wu et S.C.Chen)Y.S.Wu et S.C.Chen 4.送春(变种)C.faberi Rolfe var.szechuanicum(Y.S.Wu et S.C.Chen)Y.S.Wu et S.C.Chen 5.建兰C.ensifolium(L.)SW. 二、宽叶组(Sect.Geocymbidium Schltr.) 6.兔耳兰Cymbidium lancifolium Hook. 7.无齿兔耳兰 C.javanicum B1. 三、腐生组(Sect.Macrorhizon Schltr.) 8.大根兰Cymbidium macrorhizum Lind1.

This article describes the shapes of eight kinds of Cymbidium plant's stems. The writer puts his stress on this fact: The stems of Cymbidium plants are made up of two parts false turgid bulbs and vertical rhizomes. He also introduces the biological traits of vertical rhizomes and how to make good use of them in our production of orchids
