Metabolomics Profiling of Chilled (Coriandrum sativum L.) Primed by Silicate, Humic acid, and Gamma Radiation

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 6 degree C ±0.5. The results revealed that priming techniques had enhancement effects on 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 by 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
