tailieunhanh - Role of glycine betaine and potassium nitrate in drought tolerance using proline accumulation in rice (Oryza sativa L.)

Present investigation was carried out in the rainout shelter at Student Instructional Farm (SIF), Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (.) during Kharif (wet season) 2015 and 2016. Experiments were laid out in randomized block design with 3 replications, one variety . Swarna Sub 1and nine foliar treatments. Rice plants were exposed to drought at 60 DAT for 15 days by holding irrigation during drought treatment. During drought treatment soil moisture tension of the field was ranged from 60-80 kPa. Foliar application of different concentrations of glycine betaine (100 and 200 ppm) applied at 60 DAT and different concentrations of KNO3 (2 and 3%) applied at 30 DAT and at 60 DAT as well as their combination increased chlorophyll, proline content in leaves. | Role of glycine betaine and potassium nitrate in drought tolerance using proline accumulation in rice Oryza sativa L.
