Physical and chemical properties of pineapple fruit of cv. Pada and cv. Sarawak in response to flowering hormones
Pineapple flowering can be stimulated through artificially induced flowering (AIF) to ensure year-round production. The post effect gains from AIF is currently not universally acknowledged by previous studies, therefore, this study aims to evaluate the physical and chemical fruit properties in respo...

Pada showed a significant difference, this particular result may have been influenced by an external factor such as the environmental conditions during the fruit ripening stage due to differing harvesting periods between the treatments.

Pineapple flowering can be stimulated through artificially induced flowering (AIF) to ensure year-round production.
