Study on Biological Characteristics and Cultivation Adaption of Nine Introductional Dendrobium

Taking nine Dendrobium that were introduced from Yunnan to Nanning as materials,morphological characteristics,phenological characteristics and planting adapiton characteristics were studied,aiming to rich local Dendrobium provenances,protect and use wild Dendrobium resources.The results showed that Dendrobium chrysotoxum,Dendrobium pendulum,Dendrobium wardianum,Dendrobium densiflorum,Dendrobium thyrsiflorum,Dendrobium primulinum and Dendrobium trigonopus could grow and blossom normally.Due to its high ornamental value,it were worth to be chosen as crossing parents for cultivating ornamental new varieties of Dendrobium.
