查询词典 plant structure

It is as proper to term the plant a water structure as to call a house composed mainly of bick--- a bick building.

Research on individual bamboo biomass and timber physical structure indicated that the allocation of Guadua amplexifolia biomass to branch is higher than moso-bamboo evidently. Root shoot ratio is larger than other sympodial bamboo, so it can be considered as a good breakwind plant because of developed root and branch. Every modularity biomass above ground had significant positive correlation with basal diameter and total height, it can simulated with allometric model. The culm had large relative wall thickness and low moisture content, so it can be cultivated as fine timber-used bamboo.

通过对Guadua amplexifolia现存单株生物量结构和竹材物理结构研究，结果表明：地上部分生物量在枝条上的分配比例高于相同径级毛竹，根冠比较其他丛生竹种大，具有发达的地下根系且易形成密集林分，是良好的防风植物材料；地上部分各器官生物量与地径、全高均呈显著的正相关，可以用相对生长模型进行模拟；竹秆有较大的相对壁厚和较低的含水率，可以作为良好的材用竹种进行培育。

Its insecticidal active ingredients are sesquiterpenoid polyol esters with a dihydroagarofuran structure. These compounds are stable to light, heat, and pH, and exert a narcotic and toxic poisoning action. Celastrus angulatus contains a plant-origin insecticide with a unique mechanism of action. Celangulins, a 0.2% emulsifiable concentrate has already been developed for insect control.

是我国广泛分布的一种杀虫植物，其杀虫有效成分基本上均是以二氢沉香呋喃为骨架的多元酯类化合物，对光、热和pH值均稳定，对害虫主要表现为麻醉和毒杀作用，苦皮藤是一类作用机理独特的植物源杀虫剂，在其实际杀虫的应用上，已经开发出了0.2%苦皮藤素乳油。

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

结果表明：辰山植物区系以泛热带和北温带占优势，具有典型亚热带和温带成分交汇和南北植物分布交错特征；但保育区内种类单一，维管束植物仅有49科69属94种；主要群落是以枫香、刺槐、臭椿、三角枫和朴树等为优势树种的落叶阔叶林，以香樟和秃瓣杜英等为优势树种的常绿阔叶林，以及毛竹林；物种多样性普遍较低，Shannon-Wiener多样性指数最高为刺槐+香樟群落（1.757），Simpson均匀度指数最高值为毛竹+三角枫群落（0.163）；多样性指数曲线和均匀度指数曲线不具有一致性的变化趋势；多数群落垂直结构中无明显林下分层现象；演替前期的落叶乔木种群后续个体不足。

Effects of boron and molybdenum fertilizer on plant growth and cell ultra-microscopic structure of Chamaecrista rotundifolia were studied by pot test.

The results showed that plant height, branching number, dry matter weight and uptake of B and Mo of Chamaecrista rotundifolia were increased by application of 1.0, 3.0, 7.0 mgkg^(-1) of boric acid or 0.5, 1.0, 4.0 mgkg^(-1) ammonium molybdate, the stabilities of cell wall, cell membrane and chloroplast membrane structure enhanced, the number of chloroplast increased, and the best effects were observed by the application of 3.0 mgkg^(-1) boric acid or 4.0 mgkg^(-1) ammonium molybdate.

结果表明，施用1.0、3.0、7.0mgkg^(-1)的硼酸或0.5、1.0、4.0mgkg^(-1)的钼酸铵都能增加圆叶决明的株高、分枝数、干物质重和硼／钼元素的吸收，稳定细胞壁、细胞膜、叶绿体膜的结构，增加叶绿体的数量；其中以3.0mgkg^(-1)的硼酸或4.0mgkg^(-1)的钼酸铵为最佳施用量。

C24H30O8 is a new compound, the molecular structure of which has been determined and may be extracted from Rhodiola sachalinensis A.Bor, a plant belonging to Crassulaceae and a widely used medicinal herb due to its nice curative effect.
