Abstract

Today, application of anti-oxidant and plant growth regulators has been proposed to reducing the negative impacts of Drought stress. Ascorbic acid and sodium nitroprusside are the substances that make plants resistant to biotic and abiotic stresses. In this study, the effect of Drought stress, ascorbic acid and sodium nitroprusside foliar sprays were examined on the qualitative characteristics in summer squash plants. The experimental design was a split plot factorial with two irrigation regimes; irrigation at 75% FC and irrigation at 25% FC, as the main plots, and combination of sodium nitroprusside at three levels of 0, 50 and M and ascorbic acid at three levels of 0, 10 and 20 mM at flowering stage as subplot with three replications. The experiment was conducted in 2011 at the Zabol University research farm in south Iran. Deficit irrigation reduced seed oil content and Chlorophyll a. Also delay irrigation decreased relative water content of leaves. Ascorbic acid Spraying increased, Chlorophyll a, Chlorophyll b, total Chlorophyll, Protein and oil contents of leaves, but leaf relative water content decreased with the use of ascorbic acid. The concomitant use of 20 mM of ascorbic acid and 100 M of sodium nitroprusside achieved the greatest Chlorophyll a, Chlorophyll b, total Chlorophyll, Protein and oil contents and relative water content of leaves.
