Abstract:
The purpose of this study was to investigate the effects of different treatments on the germination rate and shorten the germination period of Zanthoxylum Oxyphyllum Edgew. The experiment was performed in two different altitudes (857 m and 1000 m A.S.L) and 7 different pretreatments viz., sulfuric acid scarification (98%) for 10 min, mechanical scarification, seed priming with gibberellic acid (2000ppm) for 24 hours, cold stratification for 1 month at 3 ºC, hot water treatment (80 ºC) for 10 min, hot ash treatment (135 ºC) for 5 min and control. Our findings indicate that the overall average percentage was higher at 857 metres above mean sea level compared to 1500 metres above sea level. Seed treatment with gibberellic acid (2000ppm) was the most effective pretreatment for both altitudes followed by cold stratification with germination percentage of 45.95% and 18.13% respectively.
