Abstract

Abstract: Experiments were conducted in pot culture the plants were allowed to grow up to 30 DAS on alternative day irrigation. On 30 to 50 day (Before flowering period) all the potted plants were grown underth th poly house. Altering the irrigation intervals was imposed drought stress as follows. One set of 60 pots were irrigated at 3 days interval and another two set of pots at 4 days and 5 days interval up to 50 DAS. The rootth length of the sunflower all the cultivar increased while stem length, total leaf area, fresh and dry weights decreased under drought stress in all the sunflower cultivars. The total chlorophyll and carotenoid content decreased under drought stress in all the sunflower cultivars. Among the cultivars, the S-275 cultivar had the lowest pigmentation when compared to other cultivars. Drought stress significantly reduced the total chlorophyll and carotenoid content.
