    The sesquiterpenes of the oleoresin essential oils of Dipterocarpus tubinatus Gaertn. f. and D. retusus Bl. were analyzed by GC and GC / MS / DS for relative contents and season-al variations. The main compounds in the oleoresin essential oil of D. tubinatus are δ-elemene, α-gurjunene, γ-murolene, α-cadinene, and the α-gurjunen relative content is highest. Then, the main compounds in oleoresin essential oil of D. retutsus are allo-aromadendrene and α-humulene, and the allo-aromadendrene relative content is highest. Seasonal variations were different at highly levels for δ-elemene. α-gurjunene, γ-muurolene, α-cadinene, β-cubebene, γ-elemene between the oleoresin essential oil collected in dry season and the oleoresin essential oil collected in rain season of D. tubinatus. But the composition of the oleoresin essential oil of D. tubinatus was not affected by season.

    Ku-Ding-Cha as a famous traditional drinking tea was used in the south China for a long time. There are a lot of plants which belong to different families and genera were used as its original ma-terials. From the leaves of Ligustrwn purpurascens Y. C. Yang (Oleaceae), a kind of the materials of Ku-Ding-Cha in Yunnan Province, two new phenylpropanoid glycosides, ligupurpuroside A and B were isolated, together with the Z / E isomer mixture of 2- (3, 4-hydroxyphenyl) ethyl (3- 0- α- L-rhamnopyranosyi) ( 4- 0- coumaroyD-0-β-D-glucopyranoside, the mixture of osmanthuside B and its cis isomer, as well as acteoside and three known flavonoid glycosides, luteolin -7-glucoside, cosmosiin and rhoifolin. On the basis of spectroscopic evidence, the structures of the new glycosides were established as 2-(3,4-dihydroxyphenyl) ethyl- [3- 0-α- L-rhamno-pyranosyi (1→ 4)-α-L-rhamnopyranosyl] [ 4-0 -E-caffeoyl] -0-β-D-glucopyranoside and 2-β-hydroxyphenyl) ethyl [3-0 -α-L-rhamnopyranosyl(l →4)-α-L-rhamnopyranosyl) C 4-0-E-p-couOTaroyl) -0 -β-D-glucopyranoside, respectively.

    Pollen grains of 27 species representing 18 sections of Camellia have been examined by light microscope (LM), scanning electron microscope (SEM) and mostly by transmission electron microscope (TEM). From the comparison of pollen size and shape, the exine sculpture, the pollen wall ultrastructure and exine stratification, we divided the pollen grains of Camellia into 6 types: 1. rugulate-verrucate; 2. coarsely warty; 3. granulate to rugulate-granulate; 4.foveolate-reticulate; 5. rugulate-fossulate; and 6. rugulate with beaded muri. These types are not in keeping with the sections divided morphologically by Mechior (1925), by Sealy J.R. (1950) or by Chang Hungta (1981-1982).

    Taxa of the Polygonum posumbucomplex, including P. posumbu, P. longisetum and its var. rotundatum, are taxonomically perplexing. By means of conventional taxonomic me-thods, it is difficult to discriminate them from one another. Basing upon herbarium materials of about 100 sheets of specimens collected from 11 provinces in China, a quantitative analysis of the correlations between certain key characters was thus made by applying the methods of pictorialized scatter diagram and histogram so as to reexamine the validity of the above taxa. Results from both methods have indicated that this complex could be divided into three parts: (1) Individuals-with branching repent stems without a central axis, blades usually ovate, ap-pressed hairy and with caudate tips, agreed well with typical P. posumbu; (2) Individuals-with more generally erect, stems, leaves lanceolate and usually glabrous, agreed with P. longisetum; (3) Individuals-characterized by angusti-lanceolate blades with truncate-round-ed or subcordate base, agreed with P. longisetum var. rotundatum. Both diagrams also showed that these three parts are so closely related to one another that they are by no means strictly seperable. Thus it is better to treat them all as varieties of the said complex.

    Shorea chinensis forest distributing as a relict in the limited habitats of southern Mengia County, Xishuangbanna, Yunnan. Covering about 800hm2, where is a tropical consociation with a single dominant tree species Shorea chinensis ofDipterocarpaceae. The for-est is mainly charactered by evergreen mega and meso phaenerophytes with simple leathy and entire mesophylls. With 3-4 tree layers, butress appearing in the upper trees, cauliflory ap-pearing in the lower trees, abundant woody lianas and epiphytes in the interlayer, the forest is thoroughly a vegetation type of tropical rain forest. Situated on the northern border of main-land SE Asia, the forest grows under the limiting conditions of the climate, latitude and alti-tude of tropical rain forests, therefore, the forest community has some deciduous trees among the upper trees, less megaphaenerophytes and epiphytes, more abundant lianas, meso and microphaenerophytes.

    Origin, phylogeny and dispersal of Quercus from China were discussed based on studies of phylogeny, fossil history and modern distribution of Quercus. According to Takhtajan's view point of regionlizatiton of the world flora, a number of species in every re-gion of the world were counted as follows: Caribbean region with 134 species belonging to one subgenus and three sectitons (3/ 1), Indo-Chinese region 118(3/2) and east Asian region 97(3 / 2). Above regions are abundant in a number of species and can be considered as the cen-tres of majority. In conjunction with considering their phylogenetic relationships and fossil his-tory Indo-Chinese region would be however the centre of distribution and speciation and could be original place of Quercus. Original time of Quercus was suggested in early Plaeogene based on the fossil history of Quercus. Trigonobalanus has been recognized as probable ancestor of Quercus.

    In this paper, the airborne spores and pollen grains during 1987-1989 in Kunming are reported. The samples were collected from higher (24 and 14.7 m) and lower (2 m) above sea levels. The peaks of spores and pollen grains occur in Spring (1-4 monthes) and Autumn (9-11 monthes) in this city. The relationships among the quantity of airborne pollen and cli-mate and the pollen quantity from higher and lower levels are discussed. Some good results have been obtained for treatment of allergenic diseases by using the fluid extracts of pollen grains.

    Plating culture technique was used for screening high-producing of a-tocopherol variants from the culture cells of Carthamus tinctorius L. The content of α-tocopherol in cul-ture cells was measured by HPLC method. The cell variants were selected from more than 200 clones induced from single cell or small cell aggregates (2-8 cells), and found that these clones were significant difference in a-tocopherol synthesis and cell growth, a-tocopherol contents were varied from 0 to 138.9 ug/ gDW and cell growth rates were varied from 0.20 to 0.53 gDW/ l.d at the first generation of clones. There was not a significant correlation between a-tocopherol productivity and cell growth in these clones. The stability of some clones which high-producing α-tocopherol was tested. A more stable high-producing α-tocopherol clone line (CT-289) had been selected through out near 20 passages successive subculturing.

    The protoplasts isolated enzymically from monokaryotic mycelia of Lentinus edodes, Pleurotus sapidus and Pleurotus ostreatus cultured in liquid medium were electrofused by means of supplying electric field of sine wave 0.5MHz, 500PV / cm and square pulse 50us, 6000PV / cm. The colonies grew up from the fusants or protoplasts plated on solid medium af-ter electrofusion. The strains from fusants were selected by discovering clamp connection of fusant mycelia under a microscope. Frequence of regenerating strain from fusant was 61.53% between Lentinus edodes and Pleurotus sapidus, 32.58% between Lentinus edodes and Pleurotus ostreatus. It was demonstrated that fusant strains grew from the heterkaryon according to an-tagonistic action of fusant strains and parents and difference of their electrophoretogram of esterase and peroxidase isoenzyme from those of their parents. While the electrofusion method and results were discussed.
