萌发

The impact of Hg and Atrazine stresses on seed germination of Alisma orientale Juzepcz was studied using water-culture experiment.

利用水培实验方法研究了重金属汞和有机污染物阿特拉津对泽泻种子萌发的影响。

The Hg could inhibit seed germination of Alisma orientale Juzepcz, no seed germination was observed under the Hg solution in this experiment, the reason needs to be studied in the near future. Atrazine along concentration gradient could stimulate seed germination except the low concentration. The seed germination increases with the increasing atrazine content. When the atrazine concentration reaches 50mg/L, the seed germination reaches its peak.

结果表明：重金属汞对泽泻种子有抑制，未能诱发出芽来，其根源还有待于进一步的研究；有机污染物阿特拉津在一定浓度下却促进了泽泻种子的萌发，除了低浓度的T1处理比CK发芽率低以外，随着浓度的增加，发芽率逐渐升高，当阿特拉津浓度为50mg/L时，为泽泻种子发芽率最大值。

Sucrose and H3BO3 were essential for pollen germination of Alnus formosana.

The results indicated that the values of EC50 of compound 1# was 0.019 mg·L-1, against germination of Amaranthus retroflexus.

测定了1#化合物对反枝苋的抑制活性，结果表明，1#化合物对反枝苋种子萌发的EC50 分别为0.019mg·L-1。

The total extract and extracts by three solvent did not show any bioactivity against seed germination of Amaranthus retroflexus at a concentration of 12.5 mg/ml.

室内除草活性测定结果表明，总浸膏及各萃取段在浓度为12.5mg/ml时对反枝苋种子萌发、幼根和幼茎生长无明显抑制作用。

Amaranthus retroflexux L. and Trifolium repens L.. The result showed that three different extracts inhibited the germination rate of seeds and inhibited the growth of seeding and young root. The experiment showed that White clover existed obvious allelopathy and autotoxidity effect.

结果表明，地上部分水浸液、挥发物和根系分泌物显著抑制了反枝苋、苘麻和自身种子的发芽率，三部分提取物显著的抑制了苘麻、稗草和自身种子在萌发过程中芽长和根长的生长；试验表明白三叶草存在明显的化感作用且有一定的自毒作用。

The aim was to study the influence of different soils on the germination and growth of Amorpha fruticosu L.

［目的］研究不同土壤对紫穗槐萌发及生长的影响。

It is the first time that these phenomena were observed: Two nuclei are surrounded by plasma and locate at the central of the female gametophyte and the others nuclei are positioned at the fringe of the female gametophyte; Before the pollen tube enters the female gametophyte. the nuclei in chalazal end begin splitting of plasma and form multinuclear cell.4. The pollens of Gnetumc are spherical or applanate with single aperture. The ornamentation of exine is spine. The basis part of spine is lenience and the top part of spine is tip or obtuse sphere.

首次在买麻藤属植物的雌配子体中观察到2个游离核位于配子体的中央位置，且被一团原生质所包围的，其余的游离核位于边缘的现象以及花粉管进入雌配子体前，合点端的核已经发生胞质分裂形成多核细胞的现象 4、买麻藤的花粉近球形或扁平型，有单萌发孔，外壁表面具小刺状纹饰，小刺基部宽大，末端尖或钝圆。

Works on germination and storage characters of ten species seeds of Ardisia and callus induction from nine of them were evaluated.

本文对10种紫金牛属植物种子的萌发和贮藏特性进行了初步研究，同时对其中9个种进行了愈伤组织的诱导研究并获得成功。

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。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
