Description An experiment was conducted during 1991-92 and 1992-93 to study the effect of priming the seed of bread wheat (Triticum aestivum L. emend. Fiori & Paol.) with growth-regulators and inorganic salts on its performance. Seeds of ‘HD 2380’ and 'VL 616' were primed for different durations of 1-24 hr at 20°C in dark, with growth hormones [indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), gibberellic acid (GA3) and abscisic acid] and inorganic salts (potassium, calcium and triadimefon). In general seed priming with most of the treatments significantly improved the seed performance in laboratory in terms of germination (%), germination time and seedling growth (length and dry matter). Varietal response was specific to each priming treatment. In 'HD 2380' maximum germination was observed with GA3 (20 ppm), KNO3 (50 ppm) and CaS04 (75 ppm), whereas in 'VL 16', auxins (IAA and IBA) and potassium salts (KH2P04 and KN03) were most effective for germination and mean germination time. The seedling growth was highest with KNO3 (100 ppm) in 'HD 2380', whereas CaCl2 (50 and 100 ppm), indole-3.butyric acid (20 ppm) and triadimefon (20 ppm) were more effective in 'VL 616'.
