The research can offer some important references to the population ecology of endangerous plant, too. based on the dates of two different circumstances, two standard life tables of form. taais chinensis var. mcarei population are founded by mathematical technique according to premising with " space deducing time ", and the curves of survival rate, mortality rate and killing power were drew. the results showed both of the survival curves of population appeared to be a type of deevey - iii and the high mortality of seeding is one of the important reasons which caused taxus chinensis var. mairei to be endangered, which badly limited the enlargement of form. taxus chinensis var. mcarei population
由於南方紅豆杉無解析木，因而以「空間推時間」 、 「橫向導縱向」方法，將林林依胸徑大小分級，以立木級結構代表年齡結構，採用分段勻滑技術，對兩個不同生境的南方紅豆杉種群編制特定時間生命表，繪制存活曲線，結果表明不同生境的南方紅豆杉種群的存活曲線均趨于deevey -型，兩地差異較小，幼苗死亡率極高，不同生境的幼苗死亡率均達到96以上。 -
It was found that there were changes to some extent in the main characters of the days from seeding to initial heading, plant height and seed setting rate when the seeds of the tested hybrid rice combinations and their parents were sowed at different time in hainan for the seed purity identification, and the changing extent was different between some hybrids and their parents, which would affect the accuracy of purity identification
摘要通過比較不同播種時期雜交水稻種子樣品在海南種植鑒定的農藝性狀表現，發現播始歷期、株高、結實率等主要性狀均表現出不同程度的變化，且部分組合與其親本的變化幅度不同，從而影響鑒定的準確性。
