Relationship between rice heading sensitivity and male-sterile sensitivity to photoperiod in view of developmental genetics

We studied the relationship between the head-ing sensitivity and the male-sterile sensitivityin photoperiod-sensitive genie males-sterile rice(PGMSR)and conventional rice.Materialsused in this study were 7001S,a late maturingPGMS japonica strain derived from Nongken58S; Akihikari and Youmang-zaojing(YMZJ),two early maturing conventional Japonica rice;and CPSLO-17,a Wide compatible convention-al indica rice.The heading date and seed-set-ting rate of Fand Fof three cross combina-tions between PGMSR and conventional riceswere examined in phytotron which was adjust-ed at 25±1℃ with day-length of 14.5 h(LD)and 12 h(SD).The segregation ratio of fertile:sterile in Funder LD was in accordance

Promotion of Social Development by Science and Technology during the Harmonious Development of Mankind and Nature

The relationship between mankind and nature as well mankind and climate was introduced firstly, and then the necessity to remove negative value accompanying the improvement of humanized nature value was analyzed, finally the ways to insist on the unity of natural view and development view to realize the harmony between mankind and climate were proposed.

A Discourse on Human Settlements in Line with Scientiic View of Development

The primary theoretical framework of the Sciences of Human Settlements was established based on the researches and practices for decades. Nowadays, it is facing a new start in order to face the challenges of "transformation" and "restructuring" amid the process of urbanization. It means that, in both the theoretical and practical fields of the Sciences of Human Settlements, due attention should be paid to the discussions on urbanization strategies, the rethinking on balanced urban-rural development, the extension and integration of various disciplines, and the realization of experimental projects in various localities. The Sciences of Human Settlements should be more closely connected with related sciences and technologies and learn more from the traditional "Chinese wisdom," so as to establish the system of "Grand Science, Grand Humanism and Grand Arts." The practice of the Sciences of Human Settlements should highlight the integration of both strategies and methodologies, the completion of institutions, and the monitoring at the macro-level. Both the top-down strategic planning and design and the bottom-up comprehensive community construction are necessary. Now that the times of great transition brings us an opportunity to solve problems creatively, the Sciences of Human Settlements should be further researched and explored.

MAO Ze-dong's View on Traditional Chinese Medicine and Its Modern Significance

MAO Ze-dong's view on traditional Chinese medicine(TCM)can be divided into the scientific view on TCM,the development view on TCM and the future view on TCM.The core of MAO Ze-dong's view on TCM lies in its scientific nature.The basic content of MAO Ze-dong's development view on TCM includes unity of TCM and Western medicine(WM),advocating the multi-angle development of TCM from the height of Chinese national dignity,independence and self-confidence.MAO Ze-dong's future view on TCM is targeted at WM learning from TCM,integrating TCM and WM and establishing new Chinese medicine.The contemporary enlightenment of MAO Ze-dong's view on TCM is to start from reforming the medical education system before establishing new Chinese medicine.
