为了解娘娘山国家湿地公园苔藓植物区系特点,对苔藓植物的物种组成和中国特有种的迁移特点进行了研究.结果表明,湿地公园共有苔藓植物51科106属266种(含12变种),易危苔藓植物2种.苔藓植物区系可划分为17种类型,以北温带分布(17.37%)占优势,其次是热带亚洲分布(14.83%).属于热带(73种.R)区系类型的物种多于温带(65种,T)区系类型,R/T为112.31%,表现出暖温带向中亚热带过渡的特点.与邻近11个地区的苔藓植物区系谱的比较显示,娘娘山国家湿地公园与八大山最接近,其次是雷公山,此结果表明,娘娘山的苔藓植物区系符合其所处地理位置.中国特有种为喜马拉雅起源,主要向东迁移,其次向北迁移.迁移路线与慈巴沟的最相似,可能与地理位置、气候及自身的生物学特性有关.

Seasonal variations in weather have significant impacts on crop yields. The accuracy of weather data is an import-ant consideration for crop yield models. This study uses an independent in-situ weather station network to validate the accuracy of monthly t

为揭示中国橄榄(Canarium album)种质资源的遗传多样性,采用ISSR和RAPD标记对橄榄主要分布区的86份种质资源进行遗传多样性分析并构建核心种质.结果表明,基于UPGMA遗传相似系数,86份种质资源可分为3个大类;基于STRUCTURE模型聚类,可分为4个类群,这基本符合橄榄的地域性分布规律.采用ISSR和RAPD获得的中国橄榄种质资源的整体遗传多样性水平分别为0.284±0.169和0.244±0.163,多态性位点百分率分别为92.56%和100%,总遗传分化系数分别为0.127和0.1
为了解薇甘菊(Mikania micrantha)成功入侵森林群落的机制,通过模拟林下低光(30%自然光强),对遮阴下的茎伸长特征、光合特性及其生长调节剂的变化进行了研究.结果表明,在低光下薇甘菊茎的细胞分裂素、赤霉素和生长素含量显著增加;茎仍具有较高的净光合作用能力[Pn=(1.22±0.13)μmol/(m2·s)].因此,薇甘菊通过维持较高的光合效率为茎的伸长提供物质基础,同时合成更多的植物生长调节剂调控物质的再分配,将更多的生物量分配到茎,从而实现了主茎在低光下的快速伸长,这是薇甘菊克服低光限制从
为了解长期风胁迫对海防林的影响,对沿海6种林龄为8~10 a的防护林树种的叶片形态、光合特征及枝条抗性对长期风胁迫的响应特征进行了研究.结果表明,与未受风胁迫海防林相比,长期风胁迫显著降低了女贞(Ligustrum lucidum)、无患子(Sapindus mukorossi)、红楠(Machilus thunbergii)、栾树(Koelreuteria bipinnata)和弗栎(Quercus virginiana)的叶长和叶面积,也降低了女贞和栾树的叶宽和叶片分形指数;长期风胁迫显著降低了6种海
