| Outline and Purpose of the Course |
1. Ecological and genetical laboratory works on weed are made. 2. Dose response tests of weeds to herbicide are made. 3. Fields surveys on the weed vegetation are also made. |
||
| Course Goals | Master the basic techniques needed to conduct research related to the biological characteristics of weeds, competition between crops and weeds, and weed control technology. | ||
| Schedule and Contents |
About 3 sessions of lectures and basic experiments are planned for each of the following topics: 1. Theory and methods related to weed seedlings, such as breaking of weed seed dormancy Lectures and experiments will be conducted on the methods of breaking seed dormancy related to typical weeds used as research material. 2. Analyses of life history characteristics of weeds Students will gain hands-on experience in the techniques used to determine the life history characteristics of weeds, from germination to seedling or propagule formation. Various patterns of weed adaption to habitats will be examined based on experiment outcomes. 3. Analyses of genetic patterns of various traits of weeds and analyses of genetic internal structures of weed population Lectures and experiments will be held on weed crossbreeding methods and genetic pattern analyses. In addition, lectures and experiments will focus on the techniques used to analyze the genetic variation in a weed population, such as the Allozyme and AFLP techniques. From the experiment outcomes, students will make observations on the evolution of weeds and weediness. 4. Methods of testing herbicide resistance of weeds Students will master the techniques used to test the resistance of herbicide-resistant weed biotypes 5. Factor analyses and testing methods related to the competition and interactions between crops and weeds Lectures and experiments will cover the methods of analyzing the factors underlying the competition between crops and weeds and methods of testing the interactions. |
