石斛

Nobile, a good result may be obtained. To explain process of root development and mechanism of endomycorrhizal formation in D.

在人工栽培金钗石斛的过程中，使用真菌AR-18或AR-15作为菌肥，有可能取得较好的效果。

Abstract］ Objective:To select the endophytes in Dendrobium nobile Lindl and increase the yield of alkaloids by improving fermentative conditions.

［摘要］目的：筛选石斛假鳞茎中产生物碱的内生菌并通过培养优化提高次生代谢产物的含量。

MS medium supplemented with 0.5mg/L NAA and different concentrations of PP333 could make D. nobile plantlets thrived.

以MS+NAA0.5mg／L为基本培养基，附加不同浓度的PP_(333)，可促使金钗石斛幼苗茁壮生长。

Wild Dendrobium nobile should not be used as medicine, those used in China are cultivated planted so it is legal to use with certification.

野生石斛为保护品种。但国内多为人工种植，故有证明文书者可用。

Methods: The strain of endophytes which could produce alkaloids was isolated from Dendrobium nobile Lindl, and the fermentative conditions were also studied.

从新鲜石斛中分离生物碱产生菌，并对其发酵条件进行研究。

The objective of this research is to study the effects of PP333, ABA, TDZ, BA, nitrogen concentrations and sucrose concentrations on flowering in vitro of D. nobile Lindl.

本文研究了PP_(333)、ABA、TDZ、BA、含氮量和糖浓度等因素对金钗石斛组培苗花芽发生和花发育的影响。

To establish the appropriate system for selection of Agrobacterium-mediated transformation of protocorm-like bodiesof Dendrobium nobile Lindl,materials were cultured in liquid paper medium,solid culture medium and liquid filter paper bridge,with Hyg at 7 different concentrations such as 0,20,40,50,60 and 80 mg/L.

为确立农杆菌介导法转化金钗石斛类原球茎的适宜的选择体系，利用液体纸基、固体培养基与液体滤纸桥3种培养方式，以0，20，40，50，60，80 mg/L质量浓度的潮霉素梯度试验，发现不同培养方式的选择效果有所差异。

Based on the investigation of pseudobulbs horizontal elongation and growth of nobile type dendrobium, the effects of growth regulators such as GA3, 6-BA on the floral bud differentiation were studied.

摘 要：调查了春石斛假鳞茎封顶和增粗的生长情况，并以不同浓度6-BA、GA3溶液进行灌根处理，观测其对花芽分化的效应。

Objective: To study the chemical constituents of volatile oil from flower of Dendrobium candidum Wall.

目的：研究铁皮石斛花中的挥发性成分。

In the condition of stereoscopic culture, all kinds of Dendrobium had similar appropriative embryo age of germination

在离体培养条件下，不同种类的石斛萌发时具有类似的最适萌发胚龄
