国产合欢属和棋子豆属的叶结构及其分类学意义

本文通过对国产合欢属Albizia 15种及棋子豆属Cylindrokelupha的叶结构观察,发现此两属叶结构特征有明显的区别,是较好的属间区别性状,表现在合欢属(3)4级以上脉至盲脉完全被厚壁的维管柱鞘细胞深深包埋,为包埋脉,且这些包埋脉宽度相等,不逐级递减,不易辨别,多分枝;网眼较小,发育不完善,不易辨别;而棋子豆属则表现为4级以上脉逐级递减,不为较厚的厚壁细胞的维管柱鞘细胞包埋,易于辨别,网眼接近中等大小,易辨。此外,还提供了国产合欢属15种,棋子豆属8种叶结构分析的基础资料,并就其在分类上的意义作了一些探讨。     

柃属植物叶宏观结构及其分类学意义

为了探讨柃属植物属下等级的系统演化路线及一些种的具体分类学地位,采用脉络法对国产柃属植物34种1变种进行了叶宏观结构比较研究,结果显示柃属植物脉序类型皆为环节曲行羽状脉,一级脉表现为较高的一致性,二级脉与一级脉的夹角为锐角或近直角,二级间脉为简单型或复合型,三级脉多为结网型,叶缘末级脉序结环或不完全,网眼的形状和大小不规则,发育不完全或不完善;这些特征存在种间差异,可用于类群的比较和鉴别。研究同时采用UPGMA法对所选16个叶宏观结构性状进行聚类分析,根据系统树的5个分支,讨论了柃属植物叶的基本演化路线。研究证明叶宏观结构特征对本属植物分类及系统演化关系具有重要意义。

红树植物厦门老鼠簕(爵床科)的订正

重新检查了厦门老鼠簕的主模式和副模式标本后,发现原始文献对其鉴别特征"花……具两个苞片,无小苞片"描述有误,应改为"花……具两个小苞片,一个苞片"。基于标本室和野外观察,认为厦门老鼠簕在老鼠簕的正常变化范围之内,应归并到老鼠簕;不赞同把厦门老鼠簕降级为小花老鼠簕或毛鼠簕的变种的处理。报道了一个新异名Acanthusilici folius var.xiamenensis。

人工胶林群落结构生物学效应的观测及若干生态因子变化规律的研究

采用近代仪器与传统小气候观测相结合的方法：研究了人工胶林群落结构的生物学效应；对若干生态因于变化规律进行了初步讨论。胶树体温与测试地日照强弱密切相关．西双版纳树温西南高，东北低，西向与北向最高温之差约为l℃；树表和浅层受日照影响直接而明显，随深度增加而减弱，树心比较间接，既受环境影响又受本身机体调节。冬季胶林边行热效应较明显，比林内树温高2℃左右，若加充分利用对防寒有一定意义。树温和气温有差别，气温变幅大，树温变幅小，有利于植物正常生活，建议直接测定树温观察寒害．胶林中适当种植茶树，冷季有增暖效果，能对轻度寒害起缓冲作用．涂黑树干法不是理想防寒措施，因边行增温不明显 况且密林深处有轻微降温趋势，可能导致寒害加重。

Comparison between two classes of selective EP(3) antagonists and their biological activities

Two different series of very potent and selective EP(3) antagonists have been reported: a novel series of ortho-substituted cinnamic acids [Belley, M., Gallant, M., Roy, B., Houde, K., Lachance, N., Labelle, M., Trimble, L., Chauret, N., Li, C., Sawyer, N., Tremblay, N., Lamontagne, S., Carrière, M.-C., Denis, D., Greig, G. M., Slipetz, D., Metters, K. M., Gordon, R., Chan, C. C., Zamboni, R. J. Bioorg. Med. Chem. Lett.2005, 15, 527] and the acylsulfonamides of ortho-(arylmethyl)cinnamates. [(a) Juteau, H., Gareau, Y., Labelle, M., Sturino, C. F., Sawyer, N., Tremblay, N., Lamontagne, S., Carrière, M.-C., Denis, D., Metters, K. M. Bioorg. Med. Chem. 2001, 9, 1977; (b) Juteau, H., Gareau, Y., Labelle, M., Lamontagne, S., Tremblay, N., Carrière, M.-C., Denis, D., Sawyer, N., Metters, K. M. Bioorg. Med. Chem. Lett.2001, 11, 747] The structural differences between the two series, along with their biological activity in vivo, in vitro, and metabolism, are analyzed. Some of those compounds, including hybrids containing the best structural features of both series, possess K(i) as low as 0.6 nM on the EP(3) receptor.
