Experimental findings reveal mechanical scarification enhances growth metrics in chironji seeds, suggesting optimal treatments.
The Chironji seeds (Buchanania lanzan Spreng.) were treated with Mechanical scarification (by hammering), Luke warm water (24 hrs.), GA3 @500, 750 & 1000 ppm (24 hrs.), H2SO4 @5 % (10 min.) and Control (Untreated). The maximum seedling height (10.27 cm), stem diameter (0.41 cm), number of leaves (13.40), leaf area (28.38 cm2), fresh shoot weight (6.76 g), fresh root weight (4.17 g), was recorded in mechanical scarification. However, the maximum shoot: root weight ratio (1.81) and maximum shoot: root length ratio (0.62) was recorded in GA3 @500 ppm and GA3 @1000 ppm respectively at 120 DAS.
