Abstract

The experiment was conducted by using randomized completely blocks design (RCBD) of analysis in a field inside the Botanical Garden and later in Agronomy laboratory of science Department at Faculty of basic Education college University of Mustansiriyah the growing season 2019/2020. The goal of this study was investigate the physiological effect of spraying Salicylic acid and Citric acid in the germination traits and oil ratio of seeds resulted from two oily crops safflower (Carthamus tinctorius) and flax (Linum usitatissimum)plants which grew under moisture stress . the first factor was three periods of irrigation each ( one week , two week, three weeks ), the second factor was spraying the treatments with Salicylic acid and Citric acid using one concentration (10−3 molar) and in two stages of growing the first one was during appearing of branches and the second was after the blooming. The results were obtained can be summarized as follows: In safflower the irrigation periods increased the shoot and radical length, in the mean while it did not affect the oil ratio or germination, while acids spraying affected significantly the increasing of the oil ratio, shoot and radicle length but not affected in germination. The interaction of the two factors (irrigation periods and spraying) affected the increasing of oil ratio, germination and radicle length but it did not affect the shoot length. In flax the irrigation periods increased the ratio of oil and the germination and shoot length but it did not affect in the length of radical, while the spraying with acids did not increased the studied characteristics in flax. The interaction of two factors (irrigation periods and spraying) increased only oil ratio but did not affect the germination or shoot and radicle length
