From the point of view of geobotany, with the method of correlative factors of growth of plants, a countrywide theoretic ecological division was done for the introduction of Camptotheca acuminata and three kinds of areas of ecological preferent zone, ecological adaptive zone and ecological unadaptable zone were divided. With the theory of synecology, the characteristic on environment, constitution, life form spectrum, diversity, similarity of plots of communities were researched. Applying the method of species association, discrete distribution, indensity index, fractal geometry, etc. to research relations between the species of the communities, space distribution of Camptotheca acuminata, structure of age of Camptotheca acuminata, in different communities. Using the theories of autoecology, distibutons of seeds on land and growth of seedlings in vertical and horizontal directions, biomass of organ of Camptotheca acuminata were analyzed. On the opinions of conservation biology, the external and internal factors impressing Camptotheca acuminata were analyzed to research the mechanism of the endangered species, and with using of CTM Model, the future development direction of Camptotheca acuminata in different communities were forecasted, and. Standing on the position of resources ecology, discussing the regularity of camptothein in Camptotheca acuminata of different sites and seeding of different resources, also the the derive technics of camptothecin.
本文从地植物学的角度,运用植物生长相关因子法,对我国喜树资源的生态适宜区进行了划分,理论上确定了我国的喜树的引种栽培的最适生活区域、生态适宜区域和不适宜生活区域;从群落生态学的角度,对野生喜树所在的典型群落的群落环境、群落组成、群落生活型谱、群落的物种多样性特点、群落样地间相似性进行了研究;从种群生态学的角度,运用种间联结性、离散分布模型、聚集强度指数、分析几何等分析手段,对野生喜树所在典型群落间的种间关系、喜树的空间分布格局、年龄结构等进行了分析;从个体生态学的角度,对不同年龄组的喜树的种子的散落的垂直分布、水平分布、时间分布及种子发芽率和千里重等特点、不同种源的人工喜树苗期特点、喜树的高生长和茎生长特点、喜树的器官生物量特点进行了研究;从保护生物学的角度,对野生喜树的濒危的内部因素和外部因素进行了探讨,并运用CTM模型对不同群落中野生喜树的种群趋势进行了预测;从资源生态学的角度,对我国地理环境下喜树中喜树碱含量的地理分布规律、不同种源的喜树幼苗中喜树碱含量变化规律进行了研究,并对喜树碱的提取工艺进行了探讨。

According to somephysiological characteristic in Camptotheca acuminata and several specific functionsof CPT, allene oxide cyclase, a key enzyme of jasmonites pathway, was isolated fromCamptotheca acuminata; mealwhile, it was investigated whether themRNA expression of CaAOC was related to the content of CPT in Camptothecaacuminata.
根据喜树自身的一些生理现象和喜树碱在其中可能参与的一些特殊作用,我们主要从喜树中克隆了茉莉酸合成途径的关键酶丙二烯氧化物环化酶(allene oxide cyclase,AOC)基因并考察了其对喜树碱含量的影响,同时还进行了其他方面的相关研究。

Results showed that the root colonization rate of S. gracilis (62.2%) was higher than that of A. conyzoides (36.5%) and P.notatum (37.3%).The arbuscule percentage showed a similar pattern. Although the biomass and P content in the shoots of the three grass species were comparable, P content in S. gracilis roots was higher than that in A. conyzoides and P. notatum roots. The species richness and hyphal density in the rhizosphere soil of S. gracilis plants were less than those of A. conyzoides and P. notatum plants, while the spore density was highest for A. conyzoides and lowest for P. notatum. Diversity index of the native AM fungi in the rhizosphere soil of P. notatum plants was slightly higher than those of S. gracilis and A. conyzoides plants. PCRDGGE analysis was consistent with the morphological results.
结果表明,柱花草根系的侵染率(62.2%)显著高于百喜草(36.5%)和藿香蓟(37.3%),丛枝率有相似的趋势;3种草地上部的生物量和含磷量没有差异,但是柱花草根系含磷量显著高于百喜草和藿香蓟;柱花草根际土壤中AM真菌的菌种丰度和菌丝密度均小于百喜草和藿香蓟,但是孢子密度大于藿香蓟而小于百喜草;藿香蓟根际土著AM真菌群落的多样性指数略高于柱花草和百喜草;PCR-DGGE分析结果与之吻合。
