Therange of fragment size of amplified products is higher than in Quercus,butthe alleles number is coincidence with in Quercus.

在栲属中扩增出的SSR片段的长度明显地大于在栎属中的片段长度，而等位基因数与栎属基本一致。

A comparative study of pollen floras between two cores: Core 17940 from the northern slope of the South China Sea and a core from the Toushe Basin in central Taiwan Province, reveals that there were three different vegetation types around the two areas during 15-40kaBP. The first type is characterized with the subtropical evergreen broadleaved forest during MIS2 (20-15kaBP). The second is the Pinus/Alnus-dominated woody plant communitites, corresponding to an interstadial summer monsoon dominated warm and humid climate and higher sea/lake level. The third is the Artemisia/Poaceae-dominated herb communities, corresponding to a stadial winter monsoon dominated warm and dry climate and lower sea/lake level.

根据南海北部17940孔和台湾中部头社孔孢粉序列对比结果，首次提出了华南地区15-40kaBP期间的三个具代表性植物群：1以青栲类为主的亚热带常绿阔叶林为第1植物群，该植物群在MIS2阶段(20-15kaBP)，为南海北部周边地区和台湾中部头社盆地周围地带性植被；2以松属或桤木属为主的木本植物为第2植物群，对应于间冰阶，夏季风盛行，降水充沛，气候暖湿，高海面；3以蒿属或以禾草为主的草本植物为第3植物群，对应于冰阶，冬季风盛行，降水少，气候暖干，低海面。

The order of remaining rate of various plants is Dicranopteris dicotoma＞Schima super-ba＞Chinese fir＞Castanopsis fissa＞Maesa japonica＞Castanopsis fargesii＞Woodwardia japoni-ca＞Angiopteris fokiensis＞ficus simplicissima and Boehmeria nivea at 308 days after decom-position.

至分解308天后，各种植物凋落物的残留率排序为芒萁〉木荷〉杉木〉闽粤栲〉杜茎山〉丝栗栲〉狗脊〉观音座莲〉三龙爪、苎麻。

The order ofpromotion is Angiopteris fokiensis＞Maesa japonica＞ficus simplicissima＞Woodwardia japonica＞Boehmeria nivea＞Castanopsis fargesii＞Castanopsis fissa＞Dicranopteris dicotoma.

促进大小表现出观音座莲）杜茎山〉三龙爪〉狗脊〉苎麻〉丝栗栲〉闽粤栲〉芒萁。

The most remarkable difference of serrate Castanopsis leaves to Castanea is that in Castanopsis the teeth are always irregularly spaced and confined to the one-half to two-thirds superior part of the lamina.

而栲属有齿类叶和栗属最大的区别是栲属中齿一般只在叶片2/3以上分布并且往往是不均匀的。

The embryological characters of Castanopsis and Castanea are very similar, thus offer embryological evidence to the sister group relationship previously proposed by molecular study on Fagaceae.

栲属和栗属的胚胎发育是最相似，为壳斗科分子系统学中栲属和栗属是姐妹群的结论提供了胚胎学证据。

The light saturation point of sun leaves in canopy was 400 μmol photons m^(-2) s^(-1), and the maximum net photosynthetic rate was 4-6 μmol photons m^(-2) s^(-1). These data showed that C. hystrix saplings are sun plants.

结果表明：1刺栲冠层阳生叶的光饱和点为400 μmol photons m^(-2) s^(-1)，最大光合速率在4-6 μmol photons m^(-2) s^(-1)之间，说明刺栲幼树保持阳生植物的特征。

The light saturation point of sun leaves in canopy was 400 μ mol photons m-2s-1, and the maximum net photosynthetic rate was 4-6 μ mol m-2s-1. These data showed that C. hystrix saplings are sun plants.

刺栲冠层阳生叶的光饱和点为400 μ mol photons m-2s-1，最大光合速率在4-6 μ mol m-2s-1之间，说明刺栲幼树保持阳生植物的特征。

Hystrix canopy declined slightly at the midday, suggesting the occurrence of reversible photoinhibition. Owing to the lower maximum net photosynthetic rate in sun leaves and the ability to effectively and consistently utilize the scattered light and/or transmitted light, C. hystrix saplings could survive low light intensity, grow well at the edge of the forest and in the understorey, and eventually become one of the dominant species in upper layer of the community.

刺栲冠层阳生叶的最大光合能力比较低，整个冠层叶能高效而稳定地利用散射和透射光，这些特征使得常绿的刺栲幼树能在林边或林下良好生长，较好地适应不同的光环境并成功渡过幼苗期，最终成为群落中的上层优势种。

The quick-growing plantation of Breakingfruit Chinkapin has sizeable stock measure in South China, though utilization research on Breakingfruit Chinkapin stays preliminary stage. Especially the research on utilizing the wood to make man-made panel is rarely reported in paper. So it is very important actual value and extensive development prospect to utilize Breakingfruit Chinkapin wood to make MDF.

黎蒴栲作为华南地区乡土速生树种具有相当规模的蓄积量，但是利用研究还处于起步阶段，特别是利用此树种制造人造板的研究尚未见报道，采用黎蒴栲木材制造MDF具有广阔的发展前景和重要的现实意义。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
