Photoinhibitive properties of super-high-yielding hybrid rice Ⅱ you 129 and its adaptation mechanism to strong light stress were investigated by measuring the light-response curve, diurnal variations of net photosynthetic rate and chlorophyll fluorescence parameters of Ⅱ you 129 leaves and compared with Shanyou 63. Photoinhibition of rice flag leaves under field conditions mainly resulted from the increase of thermal dissipation, especially for thermal dissipation depended on the xanthophyll circle, but no destruction of photosynthetic apparatus occurred. Potentially super-high-yielding hybrid rice Ⅱyou 129 was more tolerant to photoinhibition than Shanyou 63, because it had higher light saturation intensity and maximum net photosynthetic rate; more active xanthophyll cycle, and more rapid recovery ability after photoinhibition.
How to protect the disabled children’s rights and interests legally has been a very serious,urgent realistic subject.Today,the problems in the protection of the disabled children’s rights and interests become obvious,mainly including that the right to exist is not protected,the right to education is changed,the right to development is not implemented,the right to participate is not respected,and the right to be protected is not safeguarded,etc.As the legal position of the protection of the disabled children’s rights and interests is absent,it is imperative to choose the legal support ways for the protection of the disabled children’s rights and interests.
Exports of Chinese porcelain have long provided beautiful articles for daily use and collection for the people of the world, and the spread of porcelain production technology has promoted its development worldwide. Germany was the first European state to produce porcelain. In 1710, with the discovery of kaolin clay in Meissen, Dresden, porcelain articles imitating those of China were successfully
Stakeholders in the field of food safety management in China can be classified into three categories,government,food producers(farmers and enterprises),and the third-party regulatory bodies. The third-party regulation has experienced rapid development in past twenty years,and recently received considerable attention from consumers and the central government. This paper provides a review about the development,problems and future trend of the third-party regulation on food safety in China. To be specific,five forms of the third-party regulation are assessed,including media exposure,the third-party certification,regulation by consumer associations,social movements promoted by non-governmental organizations(NGOs),and regulation by industry associations. The study concludes that media and consumer associations are the major players in the third-party regulation and are highly repudiated among customers. The food certification industry has developed rapidly,but is now facing crises of confidence among consumers because of its lack of self-regulation. NGOs and industry associations still remain in the early development stages of food safety management,and therefore,are of little importance in current regulatory bodies.
