Correlation analysis linking the interaction between the application of biostimulants applied on the chilling-stressed on coriander (Coriandrum sativum L.) seeds pre- soaked in 80 mM pot. Silicate, 50 mg l^− 1 humic acid or soaked in water after exposure to γ-rays (50 Gy) and the improvement in the photosynthetic pigments (μg/g D. wt. in coriander leaves) and carbohydrate contents (g/100 g D. wt.) at the vegetative and flowering stages. *. The data in this figure represent the relative values percentage in compare to the control for the results in Tables 2 and 5 (the value/control*100)
