查询词典 upper growth

It proves that tree top leaves suffer from water stress and hydraulic limitation becomes greater with tree height.Water stress influence tree height growth in several aspects:firstly is the influence of exterior water condition,and community average tree height is positive with exterior water condition.Secondly, hydraulic limitation influences individual tree structure and function.Xeromorphic structure,Lower water potential and turgor pressure limit cell division and expansion,which restrict gas exchange and carbon assimilation capability.However,respiration consumption increases with the spread of tree crown.Shortage of nutrient limits carbon investigation on new leave growth and may ultimately limit tree growth.Thus,the main limitation of tree height is water.

水分对树高生长的限制首先是外在的水分状况，群落的总体高度随外界水分状况的变差而变矮；再就是水力限制对单株树木的结构和功能的影响，水势降低、膨压减小使细胞的分裂和扩展受限，旱生型结构加剧水力对气体交换能力的限制、使光合碳同化能力受到限制、而呼吸消耗却随着树木个体的增大而增大，制造营养物质不足、使得营养亏缺、造成投入新枝叶的营养受限，最终限制了树高继续增长。

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1～5.9, the optimum pH for sporulation ranged 5.0～6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.

首先，研究了茶云纹叶枯病病菌的生物学特性；其次，通过田间抗性调查和室内人工接种鉴定，对 13 个茶树品种进行了抗病性鉴定；第三，在前人研究的基础上，对茶树抗病机理作了更深入的研究，结果发现： 1 病原菌的生物学特性病原菌的分生孢子萌发的最适温度范围为 24～27℃，菌丝生长的最适温度范围为 22～30℃；致死温度为 55℃；菌丝生长的最适 pH 范围为 5.1～5.9，孢子萌发的最适 pH 范围是 5.0～6.0；光照对病菌生长速度及分生孢子萌发影响不大，但对其产孢的影响很大，特别是有光照与无光照处理之间差异显著，光照有利于分生孢子的形成。

Results:According to the serum GH levels of provocating tests, the short-statured children were divided into three groups:complete growth hormone deficiency 25 cases, partial growth hormone deficiency 9 cases, disorders of growth hormone neurosecretion 22 cases.

结果：根据垂体功能复合刺激试验的GH检测异常结果将矮小儿分类，包括完全性生长激素缺乏症25例，部分性生长激素缺乏症9例和生长激素神经分泌功能障碍22例。

Besides playing an apparently key role in wall expansion, expansins have been implicated in an increasing number of processes including cell enlargement, seed germination, root hair formation, root growth, leaf primordium initiation,leaf growth, softening of fruits, fruit abscission and growth of the pollen tube of grasses through the stigma and the style.

目前认为扩张蛋白几乎参与了植物的整个发育过程：除具有增大细胞的功能外，扩张蛋白在细胞生长、种子萌发、根毛形成、根系生长、叶原基形成、叶子生长发育、果实成熟、器官脱离，以及花粉管生长方面起着重要的作用。

Method］Isolated bMSCs were cultured in vitro. rh Fibroblast Growth Factor 1(rhFGF-1)、rh Transforming Growth Factor-β1(rhTGF-β1)、rh Insulinlike Growth Factor-Ⅰ were utilizated. The proliferation of cells was detected by MTT assay, and the macroscopic histology , HE staining and immunohistochemical examinations were performed to seek the best cell factor. In vivo , to investigate the repair of the articular cartilage, bMSCs combined with fibrin glue and rhTGF-β1、rhIGF-I was compared with control group.

方法］rhFGF1、rhTGF-β1、rhIGF-I单独或联合应用对骨髓基质干细胞进行体外诱导培养，应用常规染色、MTT、免疫组织化学染色的方法筛选诱导骨髓基质干细胞成软骨细胞的最佳细胞因子，并将其与骨髓基质干细胞复合于纤维蛋白凝胶制成凝胶复合物，直接种植到兔膝关节实验性关节软骨缺损处，并与对照组相比较，观察软骨修复效果。

A disequilibrium economic growth model and Econometric model are built and decompositions of GDP growth in inter-industry sectors are made, in order to discuss the impact of industrial structure on economic growth.

在实证研究的基础上进一步探讨了外国直接投资对产业结构的作用如何影响了中国的经济增长。

While demand growth has been strong, there is a fear that annual rates of investment growth exceeding 50 percent in some of these sectors－fueled by cheap credit and overoptimistic expectations about future growth in demand－are likely to result in a buildup of excess capacity.

尽管需求的增长是强劲的，但人们担心，在这些部门高达50%的投资年增长率－－它是由廉价的信贷和对于未来需求增长过于乐观的预期所推动的－－可能会导致生产能力过剩。

While demand growth has been strong, there is a fear that annual rates of investment growth exceeding 50 percent in some of these sectors—fueled by cheap credit and overoptimistic expectations about future growth in demand—are likely to result in a buildup of excess capacity.
