A report on ginkgo resources in panxian county, guizhou province——guizhou ancient ginkgo resources investigation 5

Abstract: The ginkgo biloba of Panxian County is well known in Guizhou and its neighboring areas, not only for its economic value, but the academic significance. Phytogeographically, it still maintains a dense and integrated population, which either concentrates numerous trees forming a special "ginkgo forest-human community" in some places, or scatters in the from of woodlots, graves, and singles in other places. The population structure is like a "standing rhomb", i.e. the adult trees are far more than the seedlings, young plants, and dying ones. The ratio of female to male plants is 100∶2. The nature individuals account for 87% of the total, and the gardening from individuals, only 13%. The diversity of the germplasm resources there appears much abundant. It is precious that from ancient time till now, kinds of information, such as the growth and development of ginkgo biloba individuals, and the regeneration and succession of the community, are being enshrined there.Respective investigations in the county show there is a distribution center of the geographic ginkgo population. It is located at five small towns in the middle area of the county. The basic structure of the population is like a string of bead. Several strings of beads spread along the foot and middle part of the mountain range, the entarge to form a network in the whole county. In each "bead" of a "string", the trees distribute radiantly towards all round to a certain extent, and the more the increase of the distance to the bead core, the less the numbers of the ginkgo individuals, and even disappear. That means in the core is the community, then the woodlots, and the graves to single plant. Furthermore, the highest yield of ginkgo seed is up to 75 tons a year in the county. The locl residents have a longterm ginkgo use tradition. So it is reasonable to deduce that the ginkgo geographical population of the county is the nature one by origin, but influenced for a rather long period of primitive agricultural and economic action by local people. The growth, development and even the community regeneration of the species are still dominated by the nature. The ginkgo individuals with strong wild characteristics are so far the main body in the population.

Pollen morphology of genus chirita (gesneriaceae) in china and its systematic significance

Abstract: Morphological Studies of pollen of fourteen species of genus Chirita (Gesneriaceae) in China are reported in this paper. The pollen grains of genus Chirita are tricolporoidate, mostly suboblate, rarely spheroidal or prolate in shape, mostly subangular, rarely subcircular, circular or lobate-circular in polar view and mostly subround, rarely round or oblong in equatorial view. The study shows that pollen varies in size, colpus characteristics and ornamentation among species, series, and sections in genus Chirita. Results in this study are coincident with classification of genus Chirita at section and series levels.

Abstract: From 1996 to 2001, the author made an extensive investigation on the intertidal crabs in Naozhou Island of Guangdong. Naozhou Island area is very rich in crab resources. 63 species have identified belonging to 11 families and 34 genera, in which 43 species were of soft-intertidal zone and 20 species were of rock-intertidal zone. Crabs on this habitat fall into those of the South China Sea branch. Most types of the tropics or sup-tropics. This paper elaborates their composition and ecological distribution at Naozhou Island.

It deals with Shizhangdong-first-class waterfall of Danxia in China, and studies its forming conditions on geological background, lithological characteristics, and the external causes of flowing water, weathering, gravitational force collapse and so on. It is firmly believed that it is developed in the knichkpoint of headwarn erosion of the river, and by influence of different rocks.The Danxia landfrom is special and the ecological enviroment of Shizhangdong forms a good place for tourism.

Vegetation type classification system of taiwan islands

Abstract: Situated in the southeastern part of the Chinese matherland, Taiwan is a tropical and subtropical area, at east longitude 119°18′ to 124°34′ and north latitude 21°45′ to 25°56′, with a total area of 35990km2, including its dependent islands, the largest of these is the Punghu islands 127Km2 Two thirds of the land area is mountainous and the highest part 3590 m. There are wide plains in the west and a narrow one in the east. The climate in the north part is subtropical and the south part tropical and east-monsoon. The annual everage temperature varies from 21.7° to 24.4℃, and the annual rainfull is between 1750 and 2100 mm. The very good conditions of the temperature and rainfall make Taiwan province rich in vegetstion types and plant species. The flora of Taiwan is closely related to that of south China and the Pbilippines. Botanic data gathered during the past half century indicited the presence on the island of about 190 plant families,1180 genera, and more than 4000 species. The main vegetation types of Taiwan are dicussed and system of classification with the three characteristics proposed accordingly: such as coniferous, coniferous broadleaved mixed forest, broadleaved forest, bomboo forest, shrub, grassland,sea broad psammoherbosa, Littoral sand herbosa, coral reef shrub, Meadow, petridesert vegetation, aquatic vegetation, etc. All totals 11 vegetation tgpes,31 formation classes and 108 formations.

Primary study on the structure of bud population for platycarya longipes

Abstract: Considering the bud of Platycarya longipesas basic unit of modular population,the bud population structure of sample trees, which were 8-12 years old and located at different places on slope in karst area in the middle of Guizhou province, was studied. The results showed that the distribution of bud amount was changed with branch grades. The bud amount on the second and the third branch grade located in the middle of canopy, was the maximum,others were lesser in innermost and outermost of canopy. The bud amount on new shoots was more than that on old branch. The bud density and density of bud weight of leader_bud on new shoots of the terminal branch grade were the highest. With the change of environment,the bud population on sample trees was changed. On the middle of slope, the bud amount on sample trees and on new shoots were reduced from top to underside on slope. The bud amount and live buds amount on new shoots were the highest,but density of bud weight of leader_bud and side_bud were the lowest. On top of slope,the bud amount and live bud amount on new shoots were the highest, but density of bud weight of leader_bud and side_bud were the highest.

Physiological response of sevdral karst common tree species seedlings to water stress

Abstract: In this paper, the physiological reactions of 15 common tree species in karst forest to water stress were studied by means of the artificial simulation method of water stress. The results showed that as water stress aggravates, the chlorophyll content of each species decreased, the permeability of membrane increased, the POD activation increased at first, then decreased, the activation of NR decreased, and the amount of soluble sugar and free proline accumulation in creased greatly.
