In the Cryptocarya community, the reason for Cryptocarya concinna having high relative frequency and relative abundance is probably not it has wider range of resistance to soil variables but the range of its resistance has much wider spread in broad-leaf forest habitat, or it may just has a wider range of resistance to the limiting factor.

在厚桂群落,黄果厚桂之所以具有较高分布频度与多度,并非它对所有土壤因子具有较宽的容忍性,而可能是它能容忍的范围在阔叶林生境有较广的分布,或它仅对极限因子的容忍有较广的范围。

AQY under 100% of natural light was in the order of Pinus massoniana 〉 Castanopsis fissa 〉 Schima superba 〉 Cryptocarya concinna, while the result was the reverse under 32% of natural light.

而黄果厚棒有最大的分配到光呼吸的电子流比率。100%光下AQY的大小顺序为:马尾松〉黧蒴〉荷木〉黄果厚桂,32%光下AQY的顺序则相反。

Nei'genetic distance showed Schima superba and Cryptocarya chinensis hadsmall genetic distance between every two subpopulations of each own,but Castanopsischinensis had high genetic distance between every two subpopulations of own.

Nei遗传距离结果表明,荷木和厚桂两两亚种群间都有非常小的遗传距离,而锥栗却有大的两两亚种群间遗传距离,表明荷木和厚桂亚种群间个体的差异小,有较少的位点频率发生变化;而锥栗亚种群间个体的差异大,有较多的位点频率发生变化。

The results showed that composition of species,especially dominant species,did not change significantly in the past 22 years(1984—2006),suggesting that the Cryptocarya concinna-Cryptocarya chinensi-Castanopsis chinensis-Schima superba community(Cryptocarya community for short,the same below) was at the phase of climax and relatively stable in spe...
