Cordia sinensis Lam is a multipurpose underutilized species of arid and semiarid regions. It is commonly propagated through seeds, but germination percentage is low (50-60%) and erratic. Therefore, an investigation was undertaken to standardize the propagation technique during year 2016 at CAZRI RRS Bhuj, India. The seeds ofCordia gharafwere treated with gibberellic acid (four levels: 0, 250, 500, and 1000 ppm) and potassium nitrate (four levels: 0%, 0.25%, 0.5%, and 1%) singly or in combination and it was found that combined application of GA(3)and KNO(3)enhanced seed germination synergistically (p= .05). The treatment consisted of GA(3)250 ppm and KNO3(1%) resulted in earliest seed germination (4.33 +/- 0.33 days), maximum seed germination percentage (79.47%), and subsequent seedling growthe.g. highest leaf area (25.52 +/- 1.41 cm(2)), and maximum leaf fresh (1.59 g) and dry weight (0.72 g). However, maximum plant height was observed under GA(3)500 ppm and KNO3(1%) treatment. In conclusion, the combination treatment of GA(3)250 ppm and KNO(3)1% is an effective and practical method for improvingC. sinensisseed germination.
