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.

The earliest and reliable Castanopsis fossil records date back at least to Eocene, and subfamily Castaneoideae fossil records found from Paleocene, it is indicated that appearance of Castanopsis is not later than Paleocene . All fossil records of Fagaceae and Castanopsis report from the Northern Hemisphere and their main distribution regions are in the Northern Hemisphere . It can be concluded that the Northern Hemisphere is the center of origin of Fagaceae and Castanopsis . However, owing to the discrepancy between fossil data and results of modern botany research as well as scarcity of fossil data from key area, precise center of origin of Castanopsis cannot be inferred.
栲属在地质历史上有着比现在广泛的分布,最早、最可靠的栲属化石记录发现于始新世地层,栗亚科化石在古新世就有发现,化石记录表明栲属起源的时间不晚于古新世,所有的壳斗科及栲属的化石都发现于北半球,现代分布也主要在北半球,壳斗科及栲属起源于北半球可以确认,由于化石证据与现代植物学的研究结果有较大差异以及关键地区化石证据的不足,具体的起源地尚不能肯定。

Of 12 tomato lines, the analysis on the 4 fruit nourishment quality traits (the contents of vitamin C, total soluble solids and dry matter and ratio of sugar-acid ) was carried out to study the four kinds of disparities, which included the interspecific one, the one between two varieties in the same species , the one between the lines bred by different means in the same variety ,and the one between the different fruit-shaped lines in the same variety .The analytic method of orthogonal comparison of single degree of freedom was applied. The results showed that the line of Lycopersicum pimpinellifolium was better than the average of the lines of L.esculentum in the 4 traits at significant level of 1%, the average of the lines of var.cerasiforme was better than the average of the lines of var.vulgare in the 4 traits at significant level of 5% or 1%,and the two space mutation line(YH02-2 or YH02-6) was better than the average of the other lines of the same variation in the 4 trait, respectively, at significant level of 1%. Of the lines of var.cerasiforme , the lines with pear fruit were lower than the average of the lines with round-shaped or plum-shaped fruits in the 2traits(the contents of vitamin C and total soluble solids), at significant level of 1%,the lines with plum-shaped fruits were higher than the average of the lines with round-shaped fruits, at significant level of 1%,and the lines with yellow-colored fruits(YH02-11) was lower than the average of the lines with red-colored fruits(YH02-1and YH02-7) in the trait of the contents of vitamin C.
对12个品系进行种间、种内变种间、变种内不同选育方式间、变种内不同果实形状间在果实营养品质(果实维生素C含量、可溶性固形物含量、干物质含量和糖酸比)上的差异进行分析,采用统计学上单一自由度正交比较分析法与植物学分类相结合的方法进行分析,结果表明:醋栗番茄种品系YH02-12在4个营养品质性状上,极显著高于普通番茄种品系;樱桃番茄变种品系在4个营养品质性状上的平均水平极显著或显著高于普通番茄变种品系的平均水平;2个空间诱变品系YH02-2、YH02-6在4个营养品质性状上均极显著高于同变种的其他品系的平均水平;樱桃番茄变种品系中,梨形果品系YH02-5、YH02-8的果实维生素C、可溶性固形物含量均极显著地低于樱桃番茄变种中圆形或李形品系的平均水平,李形果品系YH02-9在4个营养品质性状上均极显著地高于圆形果品系的平均水平,黄色圆形果品系YH02-11的果实维生素C偏低于红色圆形果品系YH02-1和YH02-7。
