Abstract:
Breeding system is theoretically considered as a principal factor which has the most apparent effects on plant evolution and population genetic structure. In this paper, studies were made of the floral traits, pollen viability, stigma receptivity, pollen-ovule ratio, out-crossing index, fruit sets under a serious pollination treatments, and pollinating observation of Magnolia liliflora. The result showed that:(1) The flowers of M. liliflora were amphoterics. The life span of the flower was about 15 days. (2) The pollen viability of the flower was relatively high in 9 hours after blooming and became low 24 hours later. The pollen hardly had any viability after 56 hours. The stigmatic receptivity of the flower was strong during three days and then began to decline from the 4th day. On 7th day, the stigma completely lost its receptivity. (3) The effective pollination way of M. liliflora was insect pollination. (4) M. liliflora was out-crossing, partly selfcompatible, requiring pollinators.

Abstract:
In this paper, researches were conducted on the biomass and carbon storage of Pleioblastus amarus on the defarming-and-reafforestation land in Yuping District of Hongya County by adopting the multiple linear regression and curves models of shape factors, organs' biomass and total biomass. The results showed that (1) The Pleioblastus amarus' average height was 7.50 m, the average DBH (diameter at breast height) was 3.48 cm, the average biomass of modular unit was 2.09kg and the stand crop was 90.02 t·hm-2; (2) By the standard of R and adjusted R square, the best model was chosen on the basis of the correlation analysis. The best model of organs' biomass-shape factors was Y=-1.245 + 0.135D + 0.147H + 0.236 d; The best model of total biomass-shape factors was Y=e(2.200-5.085/D); The best model of total biomass-organs' biomass was Y=0.109 + 1.069x1 + 2.526x2 + 1.059x3; (3) The carbon content of different organs of Pleioblastus amarus ranged from 0.421 7 g·g-1 to 0.551 1 g·g-1, and its order was as follows:rhizome > culm > underground trunk > root > branch > leaf. (4) The carbon stock was 44.55 t·hm-2 according to the measured value of carbon constant. When 0.45 g·g-1 or 0.5 g·g-1, were used for calculation, some error would appear, its maximum error could reach 16.63%.

Abstract:
In this paper, with enclosed chamber system, Medicago sativa seedlings were exposed to two CO2 concentrations levels (ambient and double ambient CO2 concentration), two temperature levels (ambient and + 2.2℃) and their combination for one growth season in order to research on its biomass accumulation and biomass allocation. The results showed that elevated CO2 significantly increased the accumulation of root, stem and leaf biomasses and total biomass. And elevated temperature increased the leaf and stem biomasses and total biomass, but had no obvious effect on the root-biomass. Elevated temperature had positive effect on the accumulation of root, stem, leaf and total biomass under elevated CO2. The combination of elevated CO2 and temperature increased Wsource/Wsink and available biomass, but decreased R/S and root biomass.

Abstract:
The introduction tests of 5 cultivars and native breed of Lippia nodiflora were conducted in Chongqing, and comparative studies were made of their phenological period, coverage area and biomass. The results showed that the coverage area and biomass of 5 Lippia nodiflora cultivars were significantly greater than those of the native breed. Among them, the coverage areas of No.4 and No.2 were far more than the others. No.4 had the highest proportion of underground biomass to total biomass, and followed by No.2. The two varieties of Lippia nodiflora were the ideal material for the control of rocky desertification and soil water conservation.

Abstract:
From the future development of the hospital, the hospital external environment quality will be an important factor for the patient. The beautiful environment of the hospital can have direct or indirect effects on patients in psychology and physiology, thus facilitating the patient treatment and rehabilitation. As a medical inalienable part, the good hospital environment plays a vital role, which is especially reflected in the rehabilitation hospital. Planning and construction of green spaces to promote the rehabilitation horticultural therapy such as:"the forest bath" in China is a newly emerging thing. Therefore, analysis of West China hospitals' Yongning rehabilitation green space planning and construction practice and summary can provide experience and reference for hospital rehabilitation builders.
