Screening of acaricidal active plants: Acaricidal activity of industrial alcohol extract from 200 plants in 50% concentration on adult mites of P.communis cuniculi was investigated in vitro.

具有杀螨活性植物的筛选：采用点滴法离体杀螨试验观察了200 味中药工业酒精提取物对家兔痒螨(P.communis cuniculi)成虫的杀灭活性。

Plants 5–12 cm. Taproot stout, 5–23 cm. Stem shortened, plants usually acaulous.

植株5-12 厘米。直根坚固，缩短，通常植株的5-23 厘米茎。

Despite of some difference effected by acetosalicylic acid between this two kind of plants,we found that the enhancement of relative membrane penetration by heavy metal stress was reduced, the peroxidation of membrane lipids was alleviated and to some degree protected the membrane from injury by Cd~(2+),thus ultimately promoted the tolerance ability of plants to heavy metal stress .

尽管乙酰水杨酸对两种实验材料发挥作用的浓度范围有一定差别，但在受镉离子污染的培养液中施加乙酰水杨酸后，乙酰水杨酸均能有效的抑制重金属Cd~(2+)胁迫引起的细胞膜透性增加、膜脂过氧化水平升高，从而延缓了重金属对膜结构的损伤，最终增强了植物体对水体重金属污染的抵抗能力。

An experiment was carried out in the greenhouse using a three-compartment rhizobox system to study effects of inoculation of arbuscular mycorrhizal fungi Glomus etunicatum, Glomus intraradices and Glomus mosseae on Festuca rubra and Agrostis hugoniana, and soil environment. Results indicate that inoculation had significant effects on AM fungi infection of the plants and plant growth, increasing dry matter and P contents of both ground parts and roots and phosphorus absorption rate of the plants, improving microbial flora in the rhizaphere and water stability of soil aggregates.

采用三室隔网装置，就Glomus， etunicatum、intraradices、Glomus mosseae对2种高山草地植物和土壤环境的影响进行了研究结果表明：接种AM真菌对草地植物的侵染和生长均具显著效应，植株地上部、根系干物重以及含磷量、吸磷量均显著高于不接种处理，菌根菌丝对植株吸磷的贡献率达

Based on preliminary evaluations of the use of common indoor plants for indoor air purification and revitalization, ALCA joined NASA to fund a study using about a dozen popular varieties of ornamental plants to determine their effectiveness in removing several key pollutants associated with indoor air pollution.

基于对使用普通室内植物净化室内空气和再生新鲜空气的初步评估，美国园林产业联合会与美国国家航空航天局共同赞助了一项研究。该研究用约12种常见的观赏植物，测定它们清除与室内空气污染相关的几种主要污染物的效力。

The aim of this study was to reveal the adaptation response of limestone plants to light and water. The light response curves of limestone plants Alchornea trewioides, Bauhinia championii, Pteroceltis tatarinowii, Sapium rotundi folium were measured with Licor-6400 Photosynthesis Analyzer in Karst area, and parameters of photosynthesis were simulated by non-rectangle hyperbolae function.

为阐明石山植物对光与水分的适应能力，采用Li-6400光合作用测定系统，对岩溶区石山植物红背山麻杆、九龙藤、青檀和圆叶乌柏生长盛期的光响应曲线进行了测定，并利用非直角双曲线模型对4种植物光合作用生理参数进行拟合。

The results showed that (1)There are 15 species and one variety distributing in China and 13 speeies and one variety distributing in Generalized Hengduan Mountains Region, so that the region is the area where Aletris L. plants most densely distribute in East Asia and representative Aletris L. plants at a11 the evolution stages can be found.

结果表明，(1)中国共分布有粉条儿菜属植物15种1变种，而广义的横断山地区集中分布有13种1变种，是东亚粉条儿菜属植物分布最为集中的地区，而且包含该属植物各个进化阶段的代表。

In the T1 generation, ten from 30 plants showed kanamycin-resistance. And, PCR amplification confirmed that 8 plants of them had specific fragment of chitinase, but no specific fragment ofβ-1, 3-glucanase. In this study an amaranth agglutinin gene was also cloned from Amaranthus retroflexus for obtaining aphids resistant transgenic cotton.
