查询词典 plant structure

We found a clear trnK5'-matK-trnK3' structure in Ophioglossum petiolatum, Lycopodiella cernua and Selaginella doederleinii. PCR with degenerate primers failed to amplify any trnK or matK fragments from other ferns or allies. However, dot blot hybridization showed distinct signals in these plant failed to amplify matK fragments.

本论文鉴定原始陆生植物其他未被检视的重要类群中叶绿体matK基因的存在，结果发现瓶尔小草、过山龙、生根卷柏都有trnK5'-matK-trnK3'的结构，以RT-PCR侦测matK表现时，瓶尔小草和过山龙都有侦测到讯号，但生根卷柏却没有，显示matK的表现在原始陆生植物似乎不是那麼一致。

According to the phytosociological theories and methods of Braun-Blanquet's school, the regional savanna vegetation of the dry-hot valleys of Yuanjiang river had been investigated. Based on the principle of fidelity degree, the typical 110 releves taken from every sampling stands of the dry-hot valleys were sorted up from below to upper into 15 Associations, then into 5 Alliances, 2 Orders and 1 Class. A synoptic classification system of Class-Order-Alliance-Association was established for the purpose to reflect deeply the characteristics of all syntaxa there in the aspect of plant component and their abundance-dominancy, presence, cover coefficient, life form, growth form, and ecological environment, community structure, species types and so on.

采用Braun-Blanquet植物群落学研究的理论与方法，对云南元江中上游干热河谷分布的植被进行考察研究，把各处取得较典型的110个样地记录按确限度的原则由下而上归类成15个群丛、5个群属、2个群目和1个群纲，建立了元江干热河谷萨王纳植被群纲—群目—群属—群丛分类系统综合表和15个群丛表，以全面深入反映全干热河谷植物群落各级分类单位中各植物种类组成的多优度、存在度、盖度系数、生活型和生长型等特征及其群落结构、生态环境和种型类别。

After extensive survey of species of Takakia, we couldn't have found any individuals because of its limited population distribution, so we decided to add some relevant studies of conservation genetics to make up for the shortage of this project, including the analysis of effect of stand age and management regime on genetic diversity on Thuidium cymbifolium in Western China, and genetic structure of the endangered insular plant Neolitsea sericea on the Zhoushan archipelago. Results showed that the population of T.

藻苔类植物多分布于高山雪域地带，且范围极为有限，课题组经多次野外搜寻，未能采集到活体材料，而课题实施时间仅有1年，因此课题组同时积极开展云杉人工林林下大羽藓遗传多样性恢复的动态变化，以及岛屿地理隔离对濒危物种舟山新木姜子种群遗传结构的影响等研究，以弥补项目实施之不足。
