Abstract: Most of flat tea products lack their characteristics, without competitive.The main reason lies in the lack of attention on different tea cultivars processed into flat tea. This research six main varieties were used to analyse the properties of the shoots, the inner constituents, the fragrance of the tea plants and the sensory evaluation, then systematically evaluated their suitablity in processing into flat tea. Results showed that Mingshanbaihao and TianfuchaNo.11 were the most suitable to be made into flat tea with strong aroma, FuxuanNo.9 and Tezao213 were the most suitable with green color, and Fudingdabaicha was the most suitable with fresh and strong taste. Sichuan Qunti was not suitable to be processed into flat tea, but into tea with a slim and tinny shape. This research provided theoretic foundation for developing characteristic flat tea based on the unique variety resources.

Abstract: The SPAD was shown as a diagnostic tool to assess the nitrogen (N) nutrition status. The objective of this study is to evaluate the performance of SPAD as N nutrition status for rice. We conducted two years field experiment in the Ningxia irrigation area. Five N application rates were applied to rice to obtain contrasting conditions of N availability. The leaves N concentrations, SPAD and N uptake by rice were assessed. The results showed that response of SPAD to N uptake rate depends on the developmental stage of the rice. The peak periods for N uptake by rice were the jointing-booting stage to the flowering stage. Significant regression equations were established between SPAD and N uptake. The SPAD meter was demonstrated to be a useful nondestructive system to aid in the evaluation of N nutrition status in rice. However, consistency in sample seasonal timing may necessitate to correlate SPAD values.

Abstract: Anthocyanins have important biological functions, it can help plants resist diseases invasion and pest attack. In this study, we got Rosea1-transformed snapdragon by Agrobacterium-mediated method. Anthocyanins content in the transgenic snapdragon was significantly elevated. Compared with wild-type plant, the snapdragon with anthocyanins accumulation in plant effectively reduced aphid attack in farmland. Similarly, Over-expression of Rosea1 in heterologous plant tobacco also lead to anthocyanins synthesis and the transgenic tobacco showed resistance to aphids. Therefore, improving the content of anthocyanins in plants using genetic engineering technology is a useful measure for plant protection.

Abstract: In order to improve the utilization of rice bran and study the satety quality and nutritional characteristics of rice bran oil,120 unhusked rice were collected from 6 rice planting area in China, determination of Cd and Pb contents in RBO were made by atomic absorption spectrometry when oryzanol content was made by colorimetric method,fatty acid was analyzed by Gas Chromatography and cancer inhibiton experiment was carried out with HepG2.Cd content is between 0.013 ~ 0.462 (mg.kg-1) and average value is (0.111±0.043) mg·kg-1. Pb content is between 0.036~0.230 (mg·kg-1 ) and average value is (0.089±0.024) mg·kg-1.Oryzanol content is 0.33% ~ 1.56% and average value is 0.80% which is much higher than other common edible vegetable oils.The main fatty acids of RBO are myristic acid,palmitic acid,palmitoleic acid,stearic acid,oleic acid,linoleic acid,linolenic acid,arachidic acid,arachidonic acid.RBO of 0.2 mmol/L has a significant inhibitory effect on cancer cell proliferation.

Abstract: Konjac soft rot is a bottleneck limiting konjac yield caused by bacterial strain of Erwinia carotovora var. carotovora. In order to control konjac soft rot, soil samples were collected, and each sample was spread on surface of a plate seeded with E. carotovora var. carotovora in advance. Strains expressing antagonistic activities were selected and then isolated with streak plate method. One bacterial strain (named Z10) was obtained from soil by this method. In field trials, strain Z10 still showed antagonistic effect against the bacterial pathogen.

Abstract: Trade-off between vegetative growth and reproduction is an important plant adaptive strategy to environmental variability. The study investigated the Stipa grandis resource allocation and the relationship between its sexual reproduction and climate factors among three sites located along a typical environmental gradient in the Inner Mongolian Plateau. The results show that different climatic characteristics among three habitats cause the growth differentiation of S. grandis. S. grandis exhibits a prominent change on the resource allocation patterns. The number of reproductive tillers and panicles biomass allocation are significantly increased along the gradient of water availability and temperature whereas the number of vegetative tillers and root biomass allocation are reduced. The rate of the percentage increase is prominently reduced although the foliage allocation increased. It suggests that under the environments with drought and high temperature, S. grandis allocates more resources to sexual reproduction but reduces the investment in vegetative growth and asexual reproduction. Moreover, the amount of precipitation in April and May are significantly correlated with the sexual reproductive allocation of S. grandis.

Abstract: Based on the daily climate data in winter and relative meteorological yield of loquat for 2 meteorological stations in Putian from 1992 to 2009, this paper studied the disaster-inducing factors and integrated climatic index for low temperature injury of loquat. The results showed that the critical temperature for low temperature injury of loquat could be determined as 3.0°C. The disaster-inducing factors included extreme minimum temperature, the sum of daily numbers for less than or equal to 3.0°C, the sustained days of low temperature injury for less than or equal to 3.0°C, and harmful chilling accumulation for less than or equal to 3.0°C, and there were obvious correlations among these factors. According to the method of principal component analysis, an integrated climatic index was obtained. By the correlation analysis of integrated climatic index for low temperature injury and the relative meteorological yield of loquat in Putian, the value of integrated climatic index of low temperature injury was significantly negatively correlated with the yield of loquat, and could be used to analyze the degree of low temperature injury of loquat.

Abstract: There are 869 species 369 genera and 99 families wild spermatophyte in Wudalianchi. The spermatophyte diversity is complex. The dominant families are distinct and there are 14 families with more than 20 species, accounting for 56.37% in total genera and 63.52% in total species respectively. Oligotypic genera and monotypic genera account for 89.16% in total genera, 64.21% in total species. On classification of Raunkiaer life-form, hemicryptophytes and geophytes are major. On classification of ecotype, mesophytes are predominate, hygrophytes are the second.

Abstract: Understanding the toxic effect of Magnaporthe oryzae on rice to breed resistant varieties is important for environment protection. The effects of four M. Oryzae physiological races were conducted on the photosynthesis and photosynthetic pigment contents relating to hybrid rice. The results suggest that Pn、E、chl a/chl b and Car content at all growth stages, Ci and Gs at tillering stage, the content of Chl a, Chl b, Chl (a+b) at tillering stage and jointing stage are decreased significantly by the M. oryzae toxins , while Ci and Gs at jointing stage and booting stage, the content of Chl a, Chl b and Chl (a+b) at booting stage show a significant increase in their values. Photosynthesis of rice are inhibited by stomatal and non-stomatal factors in rice treated by M. Oryzae toxins. The response of rice at different growth stages is statistically different for various M. Oryzae physiological races.
