Abstract
A field experiment was conducted during winter (
rabi
) season of 2005–06 and 2006–07 taking wheat (
Triticum
aestivum
L. emend Fiori. & Paol.) genotype ‘HD 2329’ to investigate the efficacy of putrescine under water stress
condition. Putrescine (0.01, 0.1 and 1.0 mM concentrations) was applied as seed treatment, one or two foliar sprays. For
water stress treatment, the number of irrigations was reduced to three as compared to six in control. Putrescine application
enhanced plant height, leaf area, grain number, grain weight, grain yield and biological yield under non-stress as well as
under water stress conditions. Exogenous application of 0.1 mM putrescine was found the best in most of the observations.
Among mode of applications, two foliar sprays of putrescine at the time of anthesis and post anthesis performed best
over seed treatment and one foliar spray of putrescine
