To obtain more messages from Ardisia, some studies, such as characters of seeds germination and storage, factors influencing callus induction and growth, monitoring bergenin in callus of Ardisia spp and plant regeneration of Ardisia spp, were carried out. As a result, calli were obtained from nine species of Ardisia and bergenin, the major pharmaceutical element of Ardisia, was proved to exist in six of them when checked by HPLC. Plant regeneration systems were established from three species of Ardisia too. These works are all reported for the first time.

为更好地利用该属植物资源，本文对紫金牛属植物的种子萌发和贮藏，愈伤组织的诱导和培养，培养物中岩白菜素含量的检测，植株再生等问题进行了研究，首次成功地获得了紫金牛属9个种的愈伤组织并在其中6个种中检测到主要药用成分岩白菜素的存在，同时首次建立了该属3个种的再生体系。

Generally it was in favor of fresh weight increased rate of callus of Ardisia spp to use 2, 4-D instead of using IAA or NAA, while the influence of auxin on dry weight increased rate of callus of Ardisia spp was connected with explants and auxin concentration used.

总体上生长素类使用2，4-D比使用IAA或NAA更有利于紫金牛属植物愈伤组织的鲜重增长，干物质积累则还因种和外植体以及激素浓度而异。

It was observed that a number of different polypeptides are phosphorylated in the five tested development stages including non-embryogenic callus,embryogenic callus,globular embryos, torpedo-shaped embryos,and cotyledonary and mature embryos.

在测试的体细胞胚发生的5个阶段(非胚性愈伤组织、胚性愈伤组织、球形胚、鱼雷胚和子叶成熟胚)观察到许多不同的多肽被磷酸化。

Callus derived from petiole explants of Panax japomcus var. major produced three cyanidin glycosides as major anthocyanin pigments in darkness. Anthocyanin synthesis was remarkably stimulated by 2,4-dichlorophenoloxyacetic acid in combination with kinetin in MS medium. The pigment content of the callus reached up to 34. 14 mg/g fw.

从珠子参(panax japonicus var.major)叶柄诱导的愈伤组织在暗培养条件下主要形成3种花色甙色素，且均以矢车菊素为甙元。2，4-二氯苯氧乙酸和激动素的组合能明显地促进色素的合成，色素含量可达34.14mg/g fw。

Callus deried from petiole explants of Panax japomcus ar. major produced three cyanidin glycosides as major anthocyanin pigments in darkness. Anthocyanin synthesis was remarkably stimulated by 2,4-dichlorophenoloxyacetic acid in combination with kinetin in MS medium. The pigment content of the callus reached up to 34. 14 mg/g fw.

Statistic analysis indicated that the main factor which influenced callus induction and the inducting rate of fasciculated shoots were explant, the optimal medium for callus induction was MS+1.0mg/L BA+1.0mg/L NAA+0.5mg/L 2,4-D+Leaves.

论文摘要：采用正交设计方法，研究了6-BA、NAA、2，4-D及外植体4种不同因素及其组合对钟花樱愈伤组织及丛生芽诱导率的影响，试验结果统计分析表明：外植体是诱导愈伤组织和诱导丛生芽的最主要因素。

This transforms the callus into a tougher fibrocartilaginous callus, which bridges the gap between the two pieces of bone.

这个过程将血痂转变成一种更硬的纤维软骨痂，它把两块分裂的骨骼桥接在一起。

If the ratio or the concentration of 2, 4-D was higher, the callus formed quickly, but it was hygrophanous, and easy to necrosis, conversely, if the ratio or the concentration of 2, 4-D was lower, the callus appeared very slowly or could not form, and adventitious root formed directly or indirectly.

比值较高（或2，4-D浓度较高）时愈伤组织出现的时间较早，但愈伤色泽不好，呈半透明水渍状，易于褐化死亡，而比值较低时，愈伤出现得很慢或不形成愈伤，且易于直接或再分化形成不定根；这些不定根长至1.5-2.0cm时就不生长，并逐渐褐化。
