The overall yield and yield component of leguminous crop largely depends on high rate of seed emergence, adequate seedling establishment and growth and development. The experiment was carried out in the experimental field research of Faculty of Agriculture Shiraz University. The aim of this research was to evaluate the effect response of pinto bean (Phaseolus vulgaris L.) seedling emergence and growth to different seed priming. The experiment was arranged in a completely randomized design in split plot with three replications. The treatment were Pinto bean varieties at three levels (E9, E10, and Khomain), pretreatments (priming) at seven levels: 1) polyethylene glycol (PEG), 5 bar at 6 hours; 2) salicylic acid (SA), 500 mg per liter at 12 hours; 3) potassium chloride (KCl), 20 mM at 6 hours; 4) calcium chloride (CaCl2), 15 at 3 hours; 5) sodium chloride (NaCl), 15 mM at 6 hours; 6) water (H2O), at 12 hours; 7) control (without pretreatment). The results showed that the effect of pretreatments on seedling traits was significant. The highest percentage, rate, emergence index, seventh and fourteenth day energy, height and total dry weight seedling was related to the pre-treatment the H2O at 12 hours and CaCl2 at 3 hours. According to the results it can concluded that pretreatment H2O and CaCl2 had been effective on the seedling emergence components. Principle component analysis showed that Seedling emergence rate was determined as the main component. Seed pretreatment improved the establishment and uniformity of seedling emergence on bean.
