Plant Physiology Section

This section was established in 1970 with the aim to conduct basic research on physiology and nutrition of cotton crop. Since its establishment, the main focus of research scientists has been on the screening of cotton strains/varieties for thermal and water stress tolerance, integrated nutrient management, fertilizer application strategies to improve nutrient use efficiency and fertilizer use economics, soil health improvement, amino acids and growth regulators, biosafety studies of Bt cotton and seed physiology. The scientists of the section try their best to increase cotton production by managing the soil, plant and seed related problems through a coordinated approach. Apart from the allocated experimental area for field trials, the Physiology/Chemistry Section has well equipped laboratories for qualitative and quantitative studies such as pH and EC meters, flame photometers, double beam spectrophotometer, atomic absorption spectrophotometer, ICP, HPLC, GC’s, pressure chamber for leaf water potential, Osmometer, Photosynthesis measuring system, Micro Kjeldahl apparatus, centrifuges, water baths, hot plate, Soxhlet’s apparatus, Muffle furnace and sample grinding machines etc.
