The present paper deals with a cladistic analysis of 15 species of the genus
Populus
using 23 characters (13 vegetative and 10 reproductive).Idesia, a genus of
Flacourtiaceae
, is adopted to be the outgroup based on recent data of angiosperm macrosystem as well as evidence of morphological characters. The characteristic polarities of the species of
Populus
involved are then determined by employing the recent common anesstor (ANC)-
Idesia
. The Wagner tree is constructed on the basis of parsimonious analysis. The result indicates that there are three evolutionary lines in the genus
Populsu
:the first is the most primitive Sect. Lence; the second, which includes Sect.
Leucoides
and Sect.
Tacamahaca
, is considered as the most variable one; and the third includes the most advanced Sect.
Aigeiros
and Sect.
Aigeiros
and Sect.
Turanga
. A close relationship between Sect. Leuce and Sect.
Leucoides
is recognized. Sect.
Turanga
is the most advanced one in
Populus
. The morphological variation and geographic distribution of Sect.
Tacarrahaca
in China are discussed.

In the present paper it is reported that the pollen morphological characters of
Calycanthus chinensis
Cheng et S. Y. Chang were examined by scanning electron microscope for the first time and compared with that of
C.ilordusf
L. and
C. occidentalis
Hook. et Arnott (Table 1, Plate Ⅰ, Ⅱ). The comparison shows that the former was more primitive,the latter advanced, And
Calycanthus
might originate in Eastern Asia (China) from
C. chinensis
. The results were the same as the conclusions based on cytology, morphology and so on
[1,2]
. As the many differences among
C. chinensis
,
C. floridus
and
C. occidentalis
the author recognized that monotypic
Sinocaly canthus
Cheng et S. Y. Chang, whose type was
S. chinensis
(Cheng et S. Y. Chang) Chang et S. Y. Chang (=
Calycanthus chinensis
), would be admited perhaps.

Observations are reported in present paper on the morphological features and meiosis of the first filial generation (F
1
) of
Actinidia chinese
var.
chinese
(2n=4x=116)×
A. eriantha
(2n=2x=58). The hybrid plants are similar to its paternal species in some characters (e. g. flower color) or in some other characters to the materral species (e. g. anther number), while the comprehensive morphological features of the F
1
plants are largely the middle in the interval between the two parent species features. Somatic chromosome number of the hybrid is 2n=3x=87, with two sets coming from
A. chinese
var.
chinese
, the other set from
A. eriantha
. Chromosome configuration at MI of PMC meiosis is 29Ⅱ+29Ⅰ, a typical configuration for a allotriploid. Both male and female plants are highly sterile, therefore the hybrid will be horticulturally unvalued unless some methods of promoting fruit development are available.

Tropical region in China is located on the margin of Asian tropics, so-called northern tropics. In the floristic division, this region belongs to the part of Indomalaysian floristic realm. Large area of limestone mountain is situated in the southwestern Guangxi. There is alsoa certain area of primary forests, which are called limestone seasonal rain forests.Although the community types of limestone seasonal rain forests are various, some types dominated by
Burretiodendron hsienmu
occupy larger area and have great economic utility. By analysing the population composition and ecological characteristics of different species in community, most edificators belong to the normal type of population, in other words, their individuals distribute in all layers of community, including big tree, small tree, sapling and seedling, with larger number and frequency. They grow very luxuriantly. It shows that they can fit the variation of environment in the whole community carrying on normal growth and regeneration. If there is no human disturbance, they will keep their edificator position in a long period. Some heliophytes only have big trees of upper layer and several small trees of middle and lower layers, but their sapling and seedling are seldom seen. It is obvious that it is difficult to regenerate under shade condition of community. It may be said that they belong to degenerative type of population. But the variation of crown density in a comm-unity may be often occurred, so it is not easy to remove them from the community. They usually get the growing chance in the border of the forest or some part of crown gap which have enough sunshine and they grow very quickly and occupy certain space. However, their individuals are always limited. In such zonal community type, plants which belong to the adventicous type of population are seldom seen. It means that those species, which have a lot of sapling and seedling, are possible of developing into dominant or edificator, but recently lacking trees of upper layers. Because of dominants and edificators in community grow and develop well, the community composition and environment are controled by them and the companion species are relatively steady, it is very difficult to invade the community for other species. All these show that the formation and development of limestone seasonal rain forests is quite suited to the local environmental conditions and it is in a more mature stage of relative stable community type. If there is no anthropogenic disturbances and other strong influence of factors, causing essential change of the crown, the whole community will not take place obvious variation. Even if there occurs some breaking in some parts of crown, it can also recover quickly. Of course, population change of different species in the community will be frequent.In general, limestone seasonal rain forest characterized by
Burretiodendron hsienmu
mostly is composed of various species with different age in natural condition. In order to promote the regeneration and development of
Burretiodendron hsienmu
, it must be used that clear cutting in small area and remaining about 15 individuals of parents trees in 1 ha. In such a case, the natural regeneration of
Burretiodendron hsienmu
will obtain rapid development, then green mountains may be remained by means of selection method and sustained yield working. Recently, it urgently needs to establish natural protected areas, carrying on close hillsides to facillate afforestation, on the one hand, it may be better conserved original natural forests; on the other hand, it is possible to quickly recover some cutting blanks into forest. Now four reserves have been established in the centre of distributional area of
Burretiodendron hsienmu
, more effective management, brings into play multipurpose role of reserve, mentioned above goal will certainly reach.

After irrigation and fertilization, the photosynthetic rate of
Aneurolepidium chinense
community were measured by means of assimilation chamber under field condition, The results are as follows:1. It were measured 23 days after treatments, height of leaf layer of irrigation and irrigation add fertilizatiin were raised 8% and 9%; LAI of community were increased 68.97% and 99.93%; net photosynthesis per day were 2.48 and 3.76 times than contrast respectively; the biggest photosynthetic rate were 2.82 and 3.12 times than contrast respectively.2. After irrigation and fertilization, the type of diurnal change of photosynthetic rate of
Aneurolepiium chinense
community still were "double peak" curve. They were same with contrast. Only which of irrigation add fertilization (13 days after treatments) was "single peak" type, it hadn't a reduction at the noon time. Showing the type of diurnal change photosynthetic rate may was changed when the conition of water and ferility were better.3. When the temperature and relative humidity were worse or the treatment time was longer, the effects of treatment were apparent. At first measurement, the net photosynthesis per day of irrigation and irrigation add fertilization community were 1.26 and 1.17 times than contrast respecctively. At second measurement, they were 1.4 and 1.84 times respectively. At third measurement, they were 2.48 and 3.76 times respectively.

In this paper, on the basis of seasonal changes of phytoplankton biomass in the pond, the phytoplankton can be divided into four ecological species groups, according to the adaptive mode of phytplankton to the environment. Ecological species group A has a stronger adaptive ability to the environment, but the competitive ability of that is weaker, The dynamics of ecological species group B is very relative to the content of inorganic nitrogen in the water, and the content of inorganic nitrogen in the water has a little effect on the dynamics of ecological species group C. Ecological species group D always competes with group A and B.
