Changes in Growth and Nitrogen Assimilation in Maize Plants Induced by NaCl and Growth Regulators

M.G. Khan, H.S. Srivastava

Experiments were conducted to determine the interactive effects of salinity and certain growth regulators on growth and nitrogen assimilation in maize (Zea mays L. cv. GS-2). 100 mM NaCl inhibited the biomass accumulation, chlorophyll and carotenoid contents in leaves, nitrate content and uptake and nitrate reductase activity. The application of kinetin, ascorbic acid and 10 and 50 µM abscisic acid in the first experiment and 50 and 100 µM abscisic acid in the second experiment induced a substantial increase in the above parameters, the effect was highest with abscisic acid in salinized as well as non-salinized plants.

Keywords: salinity; nitrate reductase activity; Zea mays L
Subjects: carotenoids, NaCl, growth regulators; chlorophyll, NaCl, growth regulators; maize, NaCl, growth regulators; nitrate reductase, NaCl, growth regulators; nitrogen assimilation, NaCl, growth regulators; salinity, growth regulators; Zea mays
