Abstract
Maize (
Zea mays L., the third most important cereal
crop after wheat and rice, is the major kharif (summer) crop of rainfed
areas in Pakistan. The yield per hectare and total production of
maize in Pakistan is low versus an exponentially increasing population.
The objective of this work was to study the interactive effects
of phytohormones [Gibberellic acid (GA), Sodium nitroprusside
(SNP), Abscicic acid (ABA) and kinetin (KIN)] on morphological,
physiological and biochemical parameters during the germination
of maize seeds. Seeds were presoaked in different hormones, separately
or in combinations. Priming with GA+SNP+ABA+KIN enhanced
the total fresh (TFW) and dry weights (TDW) of the seedlings
in comparison to the control. Similarly, exogenous application
of GA+KN, GA+SNP, GA+SNP+ABA+KIN, SNP+KIN+ABA
increased the oxidative enzymes [catalase (CAT) and ascorbateperoxidase
(APX)] of the maize seedlings. Sugar and proteins
concentrations were increased in response to the exogenous application
of GA+SNP+ABA+KN, KN+ABA, GA+SNP+KIN,
SNP+KIN+ABA, GA+ABA and SNP+KIN. A combination of
hormones for presoaking seeds is recommended to improve the germination
characteristics which will ultimately enhance grain yield.
