The correlation between climate factors and contents of ingredient of bulbus fritillariae pallidiflorae was studied by method of correlation analysis and gray correlation analysis, and the leading affecting factors were also screened out. The results showed that the climatic factors varied greatly in different places of Xinjiang. The content of alkaloids and sipeimine have no significant correlation with average annual temperature, ground temperature, sunshine hours, relative humidity, rainfall. The content of sipeimine-3β-D-glucoside have significant positive correlation with relative humidity (P<0.01) and ground temperature (P<0.05) but have significant negative correlation with sunshine hours(P<0.05). The content of adenosine have significant positive correlation with rainfall and ground temperature (P<0.05). The content of thymidine have significant positive correlation with average annual temperature, ground temperature, relative humidity (P<0.05) but have significant negative correlation with sunshine hours(P<0.05). This result was consistent with the gray correlation analysis results. The best climate conditions for average temperature was 13—27℃, precipitation was 169—288 mm, sunshine hours was 2140—2547 h, the ground temperature was 26—41 ℃. The average temperature, precipitation, relative humidity, ground temperature played a role in the promoting synthesis and metabolism of ingredient, but the sunshine hours was inhibition synthesis and metabolism of ingredient of bulbus fritillariae pallidiflorae. The best climate of bulbus fritillariae pallidiflorae to select its GAP cultivation base, this has best significance for synthesis and accumulation of the major active ingredient of bulbus fritillariae pallidiflorae.

The antitussive, anti-inflammatory and antioxidant function of loquat flower tea were studied by the methods of cough of mice stimulated by ammonia, xylene-induced ear acute inflammatory and scavenging capability of superoxide anion free radical and hydroxyl free radical, total antioxidant capability. The results showed that both high dose group (3000 mg穔g-1) and low dose group (700 mg穔g-1) of loquat flower tea had antitussive and anti-inflammatory effect, with high doses more effective. All concentrations of water extract showed certain reduction capacities, and had scavenging effects on hydroxyl free radical and superoxide anion. The water extract (20 mg穖L-1) had the best effect (absorbance value 0.903), better than 0.2 mg穖L-1 VC (absorbance value 0.814). The scavenging rate to superoxide anion of the 10 mg穖L -1 water extract was 47.32%, and the scavenging effect on hydroxyl radical of 20 mg穖L-1 water extract was obvious, which was 91.62%. The water extract of loquat tea had strong antitussive and anti-inflammatory, antioxidant effect.

The competition index was studied in Acacia auriculiformis stands with different densities to provide theory basis for rational utilization and management of the stands. The results showed that competition index of all the organs in the A. auriculiformis stands tended to decrease with decreasing density. At the same density level, competition index of above-ground was greater than that of below-ground. Significant correlation was found among below-ground, above-ground, and total competition. Coefficients of path analysis, in three densities levels, indicated that the direct influence intensity of above-ground competition on total competition was greater than below-ground competition.

Two kinds of morphological anomalies in Cycas revoluta were observed in Fuzhou, Fujian Province. The first was that a sucking bud seedling had grown 5 pieces of abnormal leaflets, one piece with a bifurcated midrib was longer than normal leaflets, and another had a double-pieced base. And the second was that a male cone had a rosette tip, as if there were a female cone on its top. These kinds of anomaly would provide some new basic data for cycad systematics and evolution.

2016, 45(02): 167-171. DOI: 10.3969/j.issn.1009-7791.2016.02.015

Abstract ( )

PDF (374KB) ( )

To make reasonable and scientific application of Ixora species in landscape configuration, a comprehensive assessment system in landscape application was established by analytic hierarchy process (AHP). Sixteen indicators selected according ornamental value, ecological adaptation, and configuration applications, including flower color, inflorescence size, number of flowers, corolla lobes shape, florescence, proportion of single inflorescence area and leaf area, leaf color, plant height, plant type, cold resistance, illumination adaptability, waterlogging tolerance, drought tolerance, group planting, isolated planting and potted planting. Hierarchy indices were weighted and calculated by assessment matrix. The hierarchy criteria layer weights ranged from 0.2017 to 0.4547 and the index layer weights ranged from 0.0159 to 0.1308. Scoring criteria of the evaluation system was made by using three scales to assign relative importance of the various indicators. In order to validate the feasibility of the assessment model, 9 species of Ixora plants were sampled to be assessed. The evaluation results showed that I. coccinea var. bandhuca, I. coccinea, and I. chinensis had a wide landscaping application range because they got the highest score. The assessment model was feasible that could provide a reference for Ixora plants breeding and landscape applications.

Based on investigation of native plants along Renhua to Boluo proposed expressway (Renhua to Xinfeng part) in Guangdong Province, the environment adaption, cultivation characteristic, function characteristic and economic effect of 388 native species were evaluated and comprehensively analyzed with by analytic hierarchy process. The results showed that among first-grade indexes, weight of environment adaption was the highest (0.5476) which indicated the environment adaption take the most important role in greening tree species selection along expressway, while the function characteristic (0.2051) was the second factor that should be considered. Among the 14 second-grade indexes, tolerance to barren soil was the highest (0.1642). All these were decided by special soil environment, temperature and afforested maintenance and important indexes affecting the comprehensive system of greening tree species along expressway. According to AHP model, 388 native species distributed along Renhua to Boluo expressway (Renhua to Xinfeng part) in Guangdong Province were evaluated and finally found that there were 64 species presenting well with marked up to 80 and adapting to expressway greening. Combined with ornamental value, cold tolerance and supply situation in market, 20 native species were finally selected as advising greening trees applied along Renxin expressway.
