DESCRIPTION |
Plant growth and development is a complex process. A number of physiological processes are going on simultaneously and in a balance form supporting with each other. During these processes energy rich compounds are produced, breakdown during respiration, cell division and cell elongation take place. Resultantly growth and development take place. Purpose of this course is to introduce the students with different physiological processes take place in plant body and how they integrate with each other that result in economic yield of crop plants.
|
LEARNING OUTCOMES |
After the completion of this course student will familiar with the different physiological processes take place in plant body and how they integrate with each other that result in economic yield of crop plants. Plant response to physiological processes and environmental parameters. Physicological adaptation of crop plants under unfavorable and stress condition with special reference to production of major crops. After the completion of this course students will be able to integrate the economic yield with the physiological processes and upto some extent can modify according to climatic condition.
