Phenological data of 20 ligneous plants in Xi'an botanic garden from 1988 to 2002 was analyzed. The results showed that the spring phenological phenomena of all observed 20 ligneous plants had been earlier since 1988, while the autumn phenological phenomena of most observed 20 ligneous plants had been delayed. The response of the spring phenological phenomenon to the climate change was more obvious than that of autumn phenological phenomenon.

The present study investigatated the effect on the diversification of weed community, including weed abundance, dominance, evenness, biomass, and mean height after mulching straw and intercropping white clover in the tea plantation from 2005 to 2006. The results were as follows: 16 families and 31 species were found in total. In April, the dominant species characterized with slow growth, lower biomass, and less than 30 cm height; in July those who grow faster with higher biomass and height became dominant; In September, these malignant communities reduced, while the oxalis and diffusa characterized with lower biomass and low height gradually increased. In the three seasons, the weed abundance, community diversity and evenness increased, and the dominance, the biomass and average height of weeds remarkably reduced after intercropping white clover and muching straw.

There are some isoforms of PAPs showing inhibitory ability to virus infection in various organs and at different stages of development. Three different species of the protein can be isolated from leaves of pokeweed. Proteins were precipitated with 50-80% ammonium sulfate from leaves in spring, summer and autumn respectively. Proteins were purified on SP cation-exchange then on MQ anion-exchange and finally on MS cation-exchange or on MQ anion-exchange. We found that some new pokeweed antiviral proteins separated from these leaves were different from PAP, PAPII and PAPIII.

At the same time, we studied population dynamics of seed-eating rodents in the autumn and the following spring. The results showed that, without enclosure protection, most of the seeds were predated due to high predation pressure in the autumn. The emergence rate of seedlings of all the studied species significantly increased under autumn protection, complete protection, and 1-4cm burial under soil covered by litter.

The paper studied the physiological characteristics of the leaves of Cotinus coggygria Royal Purple with different colors in autumn. Three kinds of leaf colors were selected to measure the contents of chlorophyll, anthocyanin, phenylalanin ammo-nialyase activity and the water content in the leaves. The results showed that the leaves exhibited red if it had lower chlorophyll content, higher activities of PAL and higher content of anthocyanin. The green leaves had higher chlorophyll content, lower activity of PAL, less content of anthocyanin.

Seasonal variation of the distributions of microorganism in the root-zones of wetland plants (Phragmites australis, Zizania latifolia, Zizania latifolia etc.), the substrate layers of control SSPs, together with the effects of wastewater treatment were studied. The results are as follows: the numbers of microorganisms in the different plant root-zones were different; the purification effects were also different. The number of microorganisms in the substrate of the control plot becomes smaller with increasing depth. The numbers of bacteria in fall were higher than those in the summer for the three plant zones and the control, and the number of fungi and actinomyces in summer was much higher than that in the fall for control. As for fungi and actinomyces in the experimental systems, most of their difference between the summer and fall were not as big as that in the control.
