    The genus Berchemiella Nakai is an endemic genus to Eastern Asia. The taxonomic history, morphological features, anatomic structures of wood and distribution of this genus are discussed or described. There were two different ideas with respect to the concept of the genera Berchemiella and Berchemia among a number of taxonomists. H. Koidzumi, J.Ohwi and S. Kimazaki place the former in Berchemia as a section, but onthe contrary, T. Nakai, T. Yamazaki and K. Suessenguth consider Berchemiella and Berchemia as two seperate genera. According to the following differences between Berchemiella and Berchemia, (1) in the morphological faetures, Berchemiella with the features of erect tree (not twing), branches reddish brown, brown and grey with scattered raised lenticels, stipules free, sepal with a rostellum in the ventral middle part;Berchemia with of twing or bushy shrub (scarcely small tree), branches generally greenish and smooth, stipules at least connat at the base, sepal without a rostellum;(2) in the anatomic structures of wood, Berchemiella with characteristics of the differences obvious between heart wood and sapwood, pore arrangement ring-porous, vessels with less tyloses, rays more narrow and shorter (2-5cells wide and 15-30 cells long in the multiserate rays) with less crystals;Berchemia with of the differences unobvious between heart wood and sapwcod, pore arrangement diffuse-porous, vessels with more tyloses, rays wider and longer (4-7 cells wide and 60-120 cells long in the multiserate rays) with more crystals;(3) in the pollen morphology, the pollen ofBerchemiella with the characteristics of aperture with 4 thickenings where colpi and ora pass across rather large and distinct Bnd stretched along colpus, H-shape formed by colpi and ora distinct, ornamentation of exine finely reticulate with lumina indistinct and muri coarse under scanning electron microscope (SEM);the pollen of Berchemia with of aperture with 4 thickenings small and sometimes forming a ring, H-shape generally indistinct ornamentation of exine finely reticulate-foveolate or foveolate under SEM, the author supports the treatment of seperating Berchemiella from the genusBerchemia as a genus. 3 species and 1 variety in the genus, 2 species and 1 variety occur inChina. A key to species of this genu is provided and a new variety, Berchemiella wilscnii var. pubipetiolata H. Qian, is described in the paper.

    The pollen grains of 17 sections of genus Salix, including 29 species, 6 varities and 1 form are investigated under light and scanning electron microscope. The characters of pollen grains, types of aperture and ornamentation, thickness of exine and substructure of ornamentation are considered more important for distinguishing sections but vain among species in a section. Pollen grains of the natural hybrid Salix matsudana f. tortuosa X S.eriocarpa have the middle morphological characters of its parents S. matsudana f. tortuosa and S. eriocarpa. The features of pollen of individuals in a species, collected from different places, vary a little. The method UPGMA based on distance coefficient is used for descripting the relationship between sect. Urbanianae and Pentandrae. The relationship between some other sections also been discussed.

    Observations on the developmental process of the e female and male gametophytes in Astragalus membranaceus were carried but by the optical microscope, in the meantime, made cytochemical experiment for the pollen development, the main results are as follows:1. At first mitosis of pollen, a smaller hemispherical generative cell and a larger vegetative cell were formed. 2. During generative cell development, structure of cell wall was temporary. that the wall was tested by PAS reaction and by the fluorescence reaction with aniline blue always showed negative, namely, generative cell wall didn't show the properties of celluse or callose wall. 3. Course of the disintegration of wall between vegetative cell and generative cell aswell as that generative cell came into the vegetative cell. 4. In the maturepollen, generative nucleus give a strong positive Feulgen reaction, but vegetative nucleus give a weak positive Feulgen reaction. 5. Development of female gametophytes originate from subhypoclermal archesporial cells oriented in the nucellus, but only one of these directly develops into the Polyonum type embryo sac. The retativity of the external morphology of the flower bud and the development of the female and male gametophytes in Astragalus membranoccus were compared.

    In the study, height index of tree was taken as the index number of effect of climatic factors. Throgh analysis of multivariate Linear stepwise regression equation and principal component analysis, the results wers as follows:Korean pine was a relatively sensitive species iu response to climatic facors. The effect of climatic ecology factors on the growth of Korean pine was complex because different kinds of climatic ractors did not exist independently and they effected each other and restricted each other. Those factors effected Korean pine directly and indirectly in forms of single dominance or synergy or antagonism. The effect of climatic ecology factors on Korean pine was integrated influence of different factors. And each factor has differentinfluence on growth of Korean pine. The greatest iufluence was≥10℃ acumulative temperature, that was 52.79%. Raifall was the next to it, makingup 18.62%. The influence of the two was 71.41%, which were leading fa-ctors effecting Korean pine growth. regression equation was Y=0.2924577+6.26395531×10-5x2+6.45308913×10-5x4 (x2=rainfall, x4=≥10℃ acumulative temperature.)

    Cathaya argyrophylla forest is a famous Tertiary relict phytocommunity in the world. In this paper, are discussed the physiognomy, the structure, the phytocoenosium type composition interspecific association as well as community-type and its phytocoenological features. The result shows that most lifeforms are the megaphanerophytes of 84.6%, other life forms of 15.3%. The community structure was given. In 1825 M2 area of plots, the phytocoenosium type consists of 78 species, which belong to 36 families and 57 genera, the four dominant families are Lauraceae, Fagaceae, Rosaceae and Theaceae. The interspecific association of 30 species (woody plants) were analyzed. Finally, it is divided into 3 community types according to the ordination of paper stripes and similarity of communities as well as kierachical agglomerative classification. Among otherthings, the Cathaya argrophylla and Tsuga chinensis var. tchkiangensis mixed forest is a new community-type.

    In this paper, the direct and indirect ordination of the present secondary vegetation on West Lake Mountains in Hngzhou has been analysed with the polar ordinatoin method and principal components analysis method according to the notes taken from 132 releves. The present vegetation canbeen divided into 2 Associations, 6 Subassociations, 8 Variants and 20 Subvariants with both methods just similiar to the results with the clustering analysis method. The ordination maps with both methods show obviously the secondary successional serise of vegetation from the secondary shrub-herbage to the maturer secondarv mixed forests and indicate the gradient of soil conditions from xerarch to mesophytization. They reflect that the main factors resulted in the distinguishing the secondary vegetation are the water and fertility of soil.

    The toxicological response of the freshwater green alga Selenastrum capricornuium to cadmium, as well as uptake and accumulation capacity. has been studied in this paper. The results show S. capricornutum response issensitive to the toxic action of cadmium and is suitable for toxicity test of cadmium. After 96-hr exposure, the EC50 is. found to be 0.83 mg mg/l. the lethal concentration is 2ppm. In the range of sublethal concentration cadmium (0.25-1.5ppm), as the concentration of cd is increasing, the contents of DNA and chlorophyll a of S. capricornutum reduse evidently, its deoxyri-bonuclease activity, dehydrogenase activity and peroxidase activity are affected intensely. its cell division oxygen evolution and cell membrane permeability are also inhibited and destroyed significantly.
