Interdisciplinary Study of Ephedra plants in Asia

本年度，我们对巴基斯坦、内蒙古、新疆和宁夏的野生麻黄植物进行了调查，其中巴基斯坦的调查由Mikage和Takahashi于6月28日<th>至7月13日进行<th>。津田博士是金泽大学的名誉教授，也是卡拉奇大学的访问教授，他在搜索过程中指导了我们。在巴基斯坦北方阿里亚地区的18个不同地点采集了18个标本。新疆维吾尔自治区的调查是由金泽大学博士课程学生龙长风先生在三景教授的指导下进行的。调查结束后，Mikage和两个合作者（其中一个的费用由COE承担）在重庆与他们会合，我们检查了调查结果。在重庆的调查结束后，我们开始在内蒙古进行调查，直到8月12日。我们去北京租了一辆面包车， ...更多信息 北京大学蔡绍庆教授的帮助。9月8日至15日，三景和合作者（费用由COE承担）对宁夏回族自治区主要栽培麻黄植物进行了调查<th><th>，在调查点采集到了大量麻黄植物标本。测量了这些地点的纬度、经度和海拔，并收集了DNA分析样本。有时，我们也会听到当地人对麻黄资源的情况。通过对巴基斯坦耕地杂草的调查，我们发现：（1）麻黄属植物在巴基斯坦的资源仍然很丰富。（2）麻黄属植物在我国沿海地区也有分布。（3）杂草的控制和灌溉是麻黄栽培中亟待解决的问题，我们对调查获得的麻黄属植物进行了分类学、解剖学、植物化学和分子生物学研究。少

The current year, we surveyed the wild Ephedra plants in Pakistan, Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region as well as cultivated land of the plants in Ningxia Hui Autonomous Region.The survey of Pakistan was made by Mikage and Takahashi, from June 28^<th> through July 13^<th>. Dr Tsuda, the emeritus professor of Kanazawa University also the visiting professor of Karachi University, guided us during the search. In Northern Aria of Pakistan, we collected 18 specimens in 1 8 different sites. The survey of Xinjiang Uygur Autonomous Region was conducted by Mr.Long Changfeng, a doctor course student of Kanazawa University under the direction of Professor Mikage. The end of the survey, Mikage and two collaborators(the expence of one of them was covered by COE) were joined them in Chongching, and we examined the result of the survey. After the research in Chongching, we started die survey in Inner Mongolia through August 12th. We went to Peking to rent a microbus by … More help of Professor Cai Shaoqing of Peking University. Mikage and a collaborator(expence was covered COE) surveyed mainly cultivated Ephedra plants in Ningxia Hui Autonomous Region from September 8^<th> through 15^<th>.By these surveys, we could collect many Ephedra plant specimens at the investigated sites. The latitude, longitude and altitude of the sites were measured and the samples for DNA analysis were collected. On occasion, we did hearing from local peoples about situation of resource of Ephedra. We investigated weeds grown in cultivated land.From the results we obtained this year, we found the following interesting findings ; (1)The resource of Ephedra plants in Pakistan is still rich. (2)Some Ephedra plants grow on the seashore in China. (3)The most urgent points to be solved for cultivation of Ephedra plant are control of weed and irrigation.We started taxonomical, anatomycal, phytochemical as well as molecular biological researches on the Ephedra plants which we obtained through the surveys.
