Abstract
The in vitro germination of seeds of guava cv. Arka Kiran was mainly affected by contamination and seed coat dormancy. For successful in vitro germination of guava seeds, contamination control and breaking of seed dormancy are the two main steps one should fallow. An experiment on âEffect of sterilizing agent and seed treatment method on in vitro seed germination of guava cv. Arka Kiranâ was carried out at College of Horticulture, Sirsi, Uttar Kannada, Karnataka during 2021-2023. The study revealed significant influence of different sterilizing agents and seed treatment method on contamination and germination parameters. The seeds sterilized with HgCl2 (0.05%) for 6 minutes showed minimum contamination (9.81%) and the seeds treated with 10% HCl for two minutes reported maximum germination (95.52%) and minimum days taken for germination (14.93).
