中国旌节花科植物的研究

旌节花科（Stachyuraceae）最早由P．F．Siebold和 J.G.Zuccrini根据日本植物Stahyurus Praecox Sieb．et Zucc.（Fl．Jap．1:43. 1835）建立旌节花属（Stachyurus Sieb.et Zucc.）,放在海桐花科（Pittosporaceae）中,G．Bentham于1861年将它移人山茶科Ternstroemiaceae中,但由于与这两个科的差别太大,E.Gilg于1893年又从山茶科Ternstroemiaceae中移出,建立了单属科旌节花科（Stachyuraceae）,直到这次整理之前仅有14种4变种,经整理又增加2新种4变种,共计16种8变种。我国有11种7变种。

云南植物区系

云南具有丰富的植物区系,现知种子植物240科（裸子植物10科,被子植物230科）,1,984属,约13,000种。无论从那一派分类学家的系统或观点来说,云南都有众多的古老或原始的科属。从云南种子植物属15个分布区类型比较分析,云南区系明显是热带性质并且具有丰富的温带成分,热带的属占云南总属数（不包括世界分布属,下同）61.89％,温带的属却占32.19％。中国特有属在云南分布约有83属,占云南总属数4.39％,并占中国特有属224个的37.05％。

Stamina (3-) 4 (-5); libera; sed inter se eonniventia; filamentis basi parum expansis. Ovarium fere inferum; 3-5-1oculare; stigmata 3-5; demum recurva; linearia; ovula ∞. Capsula globosa; 3-5-locularis; spice loculicide dehiscens; valvis calycis lobis alternantibus. Semina ∞ ; minima; ellipsoidea; obtuse triquetra.——Herbae perennes; lactesentes; radicibus palaribus crassiusculis. Folia alterna; pinnatipartita. Flores solitarii terminalesque vel 2-3 in cymam conferti. Genus monotypicum; in provincia Hubei Sinae cresens. Typus generis: Echinocodon lobophyllus Hong. Echinocodon lobophyllus Hong; sp. nov. plate 1 Herbae diffusae; omnino glabrae; radicibus palaribus ad 5 mm crassis. Caulis ad 40 cm longus; ramosissimus. Folia alterna; petiolis 5-10 mm longis; laminis ellipticis; 5-20 mm longis; 3-15 mm latis; basi anguste cuneatis; apice obtusis; pinnatisectis vel ad medium pinnatipartitis. Flores solitarii terminales vel 2-3 in cymam conferti; pedicellis 1-5 cm longis. Calycis lobi ovato-lanceolati; 2-6 mm longi; lobulis spiniformibus exclusis 1-3 mm lati. Corolla purpureo-caerulea; tubulosa; 3-4.5 mm longa; ad medium (3-)4(-5)-lobata; lobis late ovato-diltoideis; ad 3 mm latis. Stamina inter se conniventia; filamentis liberis; 1.5 mm longis; basi expansis; ciliatis; antheris oblongis; 1 mm longis. Stylus 1 mm longus; stigmata linearia; demum recurva. Capsula globosa; 3-5 mm diam.; sed parte supera conica et 2 mm longa. Semina minima; luteo-fusca; ellipsoidea; obtuse triquetra; 0.3 mm longa. China: Hubei Province; Yunxi County; near the town; 300 m alt.; 1 Jul. 1983. Ma Yuan-jun and Hong De-yuan PB83006 (holotype; PE); the same locality; 11 Jul. 1978; Ma Yuan-jun 3921. The new genus; Echinocodon Hong; shows its systematic position in the tribe Wahlenbergieae by the inferior ovary and capsule which loculicidally dehisces above the calyx and is closely related to the genera Codonopsis; Platycodon and Wahlenbergia; from all of which it differs in having the calyx lobes with spinelike lobules and the pinnatisect or pinnatipartite leaves. From Codonopsis it differs also in having the linear stigma lobes; from Platycodon also in the capsule valves alternate with the calyx lobes and from Wahlenhergia also in having the 4(5)-colpate pollen grains. Meiosis in pollen mother cells was examined and; 8 bivalents in MI and 8 chromosomes in MII were always observed (Plate 2: 1-2). The chromosomt number is thus determined to be n=8. The pollen grains taken from the flowers which were fixed in the fields with Carnoy II fixative (6:3:1 absolute alcohol/chloroform/glacial acetic acid) were examined without further treatment under SEM; and under LM after acetolysis. The result shows that they are oblate; 4(5)-colpate (Plate 2: 3-4); with colpi 10.5μm long and 2.5μm wide and with a smooth colpus membrane (Plate 2: 5). The exine is 2-layered; with a distinct baculate layer (Plate 2:7-8). The sexine surface is covered with spinules almost regularly spaced; 0.6μm high and basally divided. The sexine between spinules consists of short ridges (Plate 2: 6). The new genus is closely related to the genera Codonopsis; Wahlenbergia and Platycodon from gross morphological point of view; but its pollen grains differ markedly from all of them. The pollen grains in Codonopsis are longly 5-colpate; and with the sexine consisting of a low relief reticulum; those in Platycodon longly 5-colporate and those in Wahlenbergia 3-porate. The pollen type of the new genus Echinocodon with short colpi is therefore probably derived from the longly colpate type of pollen like that of Codonopsis or directly from longly colporate type like that of Platycodon; and is likely more primitive than thatin Wahlenbergia.     

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。
