A Review on the Phytotomy Research of Xerophytes in China

Drought is one of the most serious problems for human beings, and threatens the survival and the development of agriculture in the world. According to the statistical data, the area of the arid and semi-arid areas occupies one third of the total continental area in the world, and about 50% in China. Drought is extremely serious in the agricultural regions in north China, and it often occurs even in the humid regions in China. The drought impact to the yield of crops in the world is the most serious in the natural disasters, and its harmfulness is about equal in the total of other natural disasters. Therefore, the research on the resistance of crops to drought is one of the problems which are paid a great attention to by the scientists of many countries, and is currently one of the research focuses. The research on which deals with a wide rage of disciplines and technologies, such as phytotomy, physiology, ecology, molecular biology and biological technology. Many achievements in scientific research on the phytotomy of the xerophytes have been obtained. This paper sums up the history and the progress of the research on the phytotomy of the xerophytes in China and discusses the development trends so as to promote the research work in the domain.
