[Method] The total anthocyanin, soluble sugar, soluble protein and free proline contents of the leaves of the five main C. annuum cultivars planted in Wenshan Prefecture, i.e., ZSZ75-1, ZSZ49-1-1, 12WS-18-1, 12ZH01 and ZS130, under the drought stress simulated by PEG-6000 were studied by using spectrophotometry, and the total osmoregulation abilities of the leaves were evaluated by using subordinate function. [Result] Under the drought stress simulated by PEG-6000, the total anthocyanin contents of the veins, mesophylls and whole leaves of the five cultivars were all as： ZSZ75-1〉ZSZ49-1-1〉12WS-18-1〉12ZH01〉ZS130, the soluble sugar contents as： 12ZH01 〉12WS-18-1 〉ZS130〉ZSZ49-1-1 〉ZSZ75-1, the soluble protein contents as： ZSZ75-1〉12ZH01〉ZSZ49-1-1〉12WS-18-1〉ZS130, and the free proline contents as： ZS130〉ZSZ75-1 〉12WS-18-1 〉ZSZ49-1-1 〉12ZH01. Furthermore, the differences among the total anthocyanin contents of the veins, mesophylls and whole leaves of the five cultivars all reached the extremely significant levels, whereas the differences among the contents of the soluble sugar, soluble protein and free proline did not reach the significant levels, the correlation degrees among the contents of the total anthocyanin, soluble sugar, soluble protein and free proline of different cultivars were also inconsistent, and the total osmoregulation abilities of the five cultivar leaves were as： ZSZ75-1 〉7SZ49-1-1 〉12WS-18-1 〉ZS130〉12ZH01. [Conclusion] The anthocyanin accumulation in the specific organs of the five C. annuum cultivars in Wenshan Prefecture is beneficial to the strengthening of the leaf osmoregulation abilities under drought stress, favoring the drought tolerance of the cultivars.展开更多

In this paper,Malmquist-DEA model is adopted to analyze the statistical data; TFP and its decomposition indicators of different pig breeding scale among the top ten pig producing provinces are calculated; both horizontal and longitudinal comparisons are made. Results show that among different pig breeding scales,free-range breeding scale is dominant in Hunan,small breeding scale is dominant in Sichuan,medium breeding scale is dominant in Sichuan and Hunan,and large breeding scale is dominant in Sichuan,Shandong and Jiangsu; among the provinces,pig production efficiency varies with breeding scale,and small-scale pig breeding in Sichuan,Guangdong and Hebei,free-range and medium-scale pig breeding in Hunan,medium-scale pig breeding in Henan and Yunnan,largescale pig breeding in the rest of the provinces,have significant efficiency advantage.展开更多
