1. IMPROVEMENT AND DEVELOPMENT OF NEW EXPRESS METHODS FOR ASSESSMENT OF THE PHYSISOLOGICAL STATEMENT OF COTTON PLANTS Head of the Project : Nabiyev S.M. Academy of Sciences of Republic of Uzbekistan Institute of Genetics and Plant Experimental Biology

2. Proposal objectives: Improvement and development of new express methods for assessment of the physisological statement of cotton plants necessary for development of new cotton varieties resistant to drought, salt and wilt.

3. Tasks: 1. Improvement and development of new express methods for assessment of the physiological statement of leaf stamina apparatus and general leaves transpiration on the bases of measurement of electrictroconductivity. 2. Improvement and development of new express methods for assessment of water and salt consuming ability of root system on the bases of measurement of electrictroconductivity. 3. Improvement and development of new express methods for diagnostics of plants resistance to the lack of humidity and wilt resistance by using of fluorescent measuring of the photosynthetic apparatus activity.

4. Expected results: 1. New express methods for assessment of the physiological statement of leaf stamina apparatus and general leaves transpiration on the bases of measurement of electrictroconductivity will be developed. 2 New express methods for assessment of water and salt consuming ability of root system on the bases of measurement of electrictroconductivity will be developed. 3. New express methods for diagnostics of plants resistance to the lack of humidity and wilt resistance by using of fluorescent measuring of the photosynthetic apparatus activity will be developed.

5. Proposed activities within the framework of the project: Physiologo- biochemical characteristics of cotton plants different according of drought, salt and wilt resistance will be studied by using different methods for revealing of the most adequate among them and assessment of the plant resistance to the unfavorable environmental factors. Testing of the developed methods for diagnostics of cotton lines and varieties resistance to the drought, salinity and wilt on the early stages of ontogenesis.
