Early growth of post-gamma irradiated Indigofera zollingeriana

Abstract

This study aims to identify the effectiveness of gamma-ray irradiation to improve Indigofera seed viability. The study employed Randomized Block Design (RBD) consisting of 5 irradiation dosage (treatment) and 4 replication. The treatment consisted of Irradiation Dosage (A) 0Gy 50Gy; 100Gy;150Gy 200Gy The observed parameter encompassed the germination percentage, mortality percentage, plumule and radicle length, and germination index. The results of ANOVA indicated that gamma-ray irradiated Indigofera seedling had a significant effect (P<0.05) on the parameters of plumule length, germination percentage, and mortality percentage. The significant effect was identified at the dosage range of 0-50 Gy. No significant difference was found at the dosage of 100-200 Gy.
