Morphological changes and quality of papaya seeds as correlated to their location within the fruit and ripening stages

Papaya seeds presents irregular and slow germination. In this sense, the evaluation of the internal morphology of the seeds may be viable and complementary in evaluating the physiological quality of seed. The objective of this study was to evaluate the morphological and physiological quality of papa...

The objective of this study was to evaluate the morphological and physiological quality of papaya seeds extracted at different ripeness stages of the fruit and the position inside of the fruit.
