Abstract: 

Arsenic is one of the toxic heavy metals in contaminated crop environments. Arsenic stress leads to ROS damages in plants. Sodium nitroprusside inhibit the production of reactive oxygen species and protect plants against ROS damages. In this research the effects of Arsenic contamination and sodium nitroprusside foliar sprays was examined on the quantitative characteristics in bitter squash plants. The experimental design was as factorial in the basis of completely randomized block desighn with 3 replications, sodium nitroprusside in 3 levels; 0, 50 and 100 mM and arsenic contamination in four levels 0, 30, 60 and 90 mg. kg-1. The experiment was conducted in 2011 at the Zabol university greenhouse. Heavy metal stress reduced number of fruits per plant, seed weight, seed yield, fruit size, fruit weight and chlorophyll fluorescence. Application of 100 mM sodium nitroprusside had the greatest number of fruits per plant, seed weight, seed yield, fruit weight, fruit diameter and chlorophyll fluorescence. This results sugestes that sodium nitroprusside can relieve arsenic toxicity on fruit yield, seed weight, fruit fresh weight and fluorescence.
