Abstract
AMINES play an important role in the plant response to adverse ………environmental conditions including salt and osmotic stress. In this investigation, the complemented effect of putrescine amine (put), biofertilizers and mycorhiza on date palm zaghloul genotype irrigated with salinized water and grown in reclaimed salinized soil was studied. The data indicated that the selected plant growth promoting rhizobacteria in the presence of putrescine amine make and/or enable date palm zaghloul genotype to increase its tolerance and adaptation to grow in the reclaimed-salinized soil. The treatments reduced salt-induced oxidative damage, increased productivity of date palm and improved its fruit quality. These results may be due to the increase in the photosynthetic pigments, organic solutes, promoting growth substances (GA, IAA and cytokinins), and activities of oxidant enzymes. Moreover, a decrease in the levels of lipid peroxidation and inhibitor substances (ABA) may be related. The most effective interaction treatments were pronounced at 2.5 mM putresine due to more increase in the activities of ascorbate peroxidase (APOX) glutathione reductase (GR) and superoxide dismutase (SOD) and more decrease in lipid peroxidation. The interaction treatments with put at 5 mM increased disamine oxidase (DAO) and polyamine oxidase (PAO) activities compared to the other interaction treatments. The activates of these two enzymes produce hydrogen peroxide H2O2 which may act in structural defense as a signal molecule and decreasing the production of polyamines against salt-induced oxidative damage in date palm. Further investigations are needed to explain the mechanisms develop in date palm grown in stress condition.
