Interdisciplinary Study of Ephedra plants in Asia

本年度，我们对巴基斯坦、内蒙古自治区、新疆维吾尔自治区的野生麻黄植物以及宁夏回族自治区的野生麻黄植物的耕地进行了调查。金泽大学名誉教授兼卡拉奇大学客座教授津田博士在搜索过程中指导我们。在巴基斯坦的北阿里亚，我们在18个不同的地点收集了18个标本。这项新疆维吾尔自治区的调查是由金泽大学博士生龙长峰先生在Mikage教授的指导下进行的。调查结束后，Mikage和两位合作者(其中一位的费用由COE支付)加入了他们在重庆的行列，我们检查了调查结果。在重庆调研后，我们开始在内蒙古进行调查，一直持续到8月12日。我们去北京租了一辆…的小巴北京大学蔡绍庆教授的更多帮助。Mikage和一位合作者于9月8日至15日对宁夏回族自治区主要种植的麻黄植物进行了调查，通过这些调查，我们可以在调查地点收集到大量的麻黄植物标本。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了解。我们对种植在耕地上的杂草进行了调查，从今年的结果中，我们发现了以下有趣的发现：(1)巴基斯坦的麻黄属植物资源仍然丰富。(2)中国海边生长有麻黄属植物。(3)麻黄属植物栽培中亟待解决的问题是杂草的防除和灌溉。通过调查，我们对麻黄属植物进行了分类学、解剖学、植物化学和分子生物学的研究。较少

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.
