| Abstract: Chilling escape strategy using safe growth bio stimulators viz., is the aim of this work. Dry coriander seeds were primed in humic acid (50 mg. l-1), potassium silicates (80 mM) or irradiated by γ-rays (50 Gy) before priming in tap water, then all previous treatments were incubated for 16 h at 6ºC ±0.5. The results revealed that priming techniques enhanced morphological characteristics and metabolomics. Nitrogenous constituents, polyamines, and elements increased nutritional values in chilled or non-chilled coriander plants. While saturated fatty acids decreased in chilled coriander, the unsaturated fatty acids and unsat/sat ratios increased in chilled and primed plants. Also, the data obtained showed fluctuations within quantities of 43 volatile compounds. volatile oil separated using a GC mass spectrometer either increased, decreased, disappeared, or newly appeared under chilling. Thus, the recommendation is priming coriander seeds before planting is a powerful technique that renders fortification and tolerance to repair physiological damages under chilling. | ||||
