Abstract

Physiological quality deterioration during storage is a major factor contributing to the reduced germination capacity of rice seeds. Revitalization treatments are therefore essential to restore seed viability and promote optimal seedling development. One promising approach involves the application of plant growth regulators (PGRs) from the polyamine group, such as putrescine. This study aimed to assess the effectiveness of varying concentrations and soaking durations of putrescine in improving the viability of deteriorated rice seeds. The experiment was conducted using a Randomized Block Design (RBD) with two factors: putrescine concentrations (0 ppm/ soaking in distilled water only, putrescine 15 ppm, putrescine 20 ppm, and putrescine 25 ppm) and soaking durations (3, 6, and 9 hours). The parameters evaluated included germination percentage and germination rate. Results indicated that treatment with 20 ppm putrescine combined with a 6-hour soaking period yielded the most significant improvement in seed viability. These findings suggest that putrescine treatment can effectively restore the physiological quality of rice seeds affected by storage-induced deterioration.
