In order to evaluation the Effect of zeolite application and selenium spraying at water deficit stress conditions soluble sugars and cell membrane peroxidation traits in medicinal pumpkin (Cucurbita pepo L.), an experiment was conducted in factorial based on randomized complete block design with three replication during 2010 in Takestan, Iran. The three levels of irrigation factor include normal irrigation (control), withhold irrigation at the flowering and fruit formation stages, zeolite factors include two levels of non application and use of 10 tons per hectare and selenium was sprayed at two concentration in zero and 30 grams per liter per hectare. The experiment results showed that water deficit stress increased some traits such as soluble sugars content and MDA, and decreased chlorophyll index, cell membrane stability and grain yield traits. application of zeolite under stress conditions had desirable effect on chlorophyll index trait and cell membrane stability, and also improved grain yield and decreased soluble sugars and MDA. According to the results, application of zeoilite under drought stress condition retain the moisture during stress and can be useful in improving plant growth and production.
