Effect of phosphorus fertilizer and gibberellic acid on seed and oil yield of Cheiranthus cheiri
AbstractA stady on the effect of phosphorus fertilizer levels and Gibberellic acid (GA3) concentration, on seed and oil yield of Cheiranthus cheiri was conducted. Four levels of P 0.20, 30 or 50 g/ l and three concentrations of GA3 0.50 or 100 mg/ l were applied. Results showed that the highest level of P (50 g/ l) was significantly increased 1000 seeds weight, % of linolic acid and % of olic acid (1.71 g, 17.80%, 9.17%) respectively. While 30 g/ l of P elevated % of olic acid in leaves and seeds weight (4% and 5.74 g) respectively. Gibberellic acid at 100 mg/ l was superior in increasing 1000 seeds weight, % of lenolic acid, % of linolinic acid, % of olic acid and % of total fatty acids (10.07%, 18.49%, 9.33% , 37.92%) respectively. The interaction between P levels and GA3 concentrations was highly effective on % of oil studied.
