Solanum betaceum in vitro seed germination and seedling development in response to pregerminative treatments

Abstract:

Germination and seedling development are critical stages in the life cycle of plants. Insufficient seedling emergence and inadequate establishment of woody plants are significant constraints in producing crops such as tamarillo. The application of pregerminative protocols improves the germination percentage, reduces the seedling emergence time, and improves several species in vitro. The present study was conducted to contrast three pregerminative treatments on Solanum betaceum seeds. When evaluating the pregerminative treatments, treatment T3 (imbibition for 24 hours) obtained the best results, showing an average of 21.62 days to germination, 73% germinated seeds and 2.31 leaves per explant.
