Abstract
|
|
|
|
This study was conducted to improve germination ratio of Zanthoxylum piperitum A.P. DC. seeds. Stratification for 60 days after scarification of seed with sand was germination percentage to 5.4% and GA_3, 50ppm for 24 hrs after scarification of seed with sand showed 8.9%. Soaking the seeds in GA_3, 50ppm for 24 hrs after 40 to 70^{circ}C hot water treatment for 10 minutes showed low germination of 4.4%. Based on H_2SO_4, NaOH and HNO_3, treatments, germination percentage did not improve at all regardless of soaking time. The highest germination of 91.1% was observed when seed was soaked in GA_3 100ppm for 48 hrs after stratification for 60 days at 4^{circ}C. Kinetin treatment at 50ppm for 24 hrs had the greatest germination percentage of 31.7% but it did not improve germination ratio compared to GA_3 treatment.
