[Method] Eight sowing times were designed, March 20 and 30, April 10 and 30, May 15, June 1, 10 and 20, respectively in Changsha of Hunan. Thirteen sowing times were designed in Hainan, January 28, February 12 and 27, March 14 and 29, April 13 and 28, May 13 and 28, June 12, July 1, 12 and 27, respectively. Peiai 64S was gradually managed and recorded heading stage during cultivation, and the effects of different climate influencing factors, such as daily mean temperature, daily maximum temperature, daily minimum temperature, duration of day at 0-25 d before heading （namely pollen mother cell meiophase）, on pollen fertility were analyzed to confirm sensitive periods of light and temperature. [ResuLt] There was a big difference in sensitive period among the same cytoplasmic male sterile （CMS） in different climatic regions. The sensitive period of Peiai 64S was in first four phases, phases V, VI, VII, VIII （0-13 d） in Changsha of Hunan, which was in last four phases, phases I, II, III, IV （13-25 d） in Haikou of Hainan. Under natural conditions, Peiai 64S pollen sterility rate were all more than 99.5% and seed-setting rates all less than 0.5% in Haikou, so production of hybrid seeds was safe. Its pollen sterility rate was 21.3%- 100.0% in Hunan, so its security coefficient of hybrid seeds production was lower than that in Hainan. [Conclusion] The security coefficient of hybrid seeds production of CMS Peiai 64S is lower than that in Hainan.展开更多

It discusses the origin of the short story in general and preconditions for the popularity of the new genre the Iranian literature of the 20th century, and also about the first successful collection of short stories that introduced it to the public. Also the development process of the short story and principle factors in every stage of its emergence as an independent genre of prose, as well as the thematic range are the main aspects among others to be analyzed in the article. It is historically documented that the Islamic state was established in 1979 after the fall of the Shah. And the very event had big impact not only on the social and political life of the country, but also on the cultural and literary life of the Iranians of the time. The significance of the revolution was such that it divided the literature to be known as the ＂pre-revolution＂ and ＂post-revolution＂ periods. Therefore this article is aimed to observe how this historic event had influenced the short story in particular and the distinct features of the works created during the two periods. The next period which stands out in the development of the short story is during the late 90s and the beginning of the 2000, where the genre experienced aesthetic innovations and experiments with new forms and styles. The distinct feature of the period is mainly in its topics it deals, among other the effects of the globalization and popular culture brought forth, isolated individual, urbanization, climate change and its destructive outcome and the social conflicts resulting from them. Such global issues caused the established writers to look out of their borders and open up to the concerns of the planet, and by doing so establishing new schools of thought and style among the writers of short story in modem Iranian literature. Finally the article will overview the role of the Iranian contemporary female short story writers, children＇s literature and the works of the immigrant Iranian authors that continue the traditions of the Persian literature outside Irma.展开更多
