Bananas develop plum-blossom speckles and the fruit easily drops from the stem
Bananas with colored spots (plum-blossom speckles) easily drop from the stem
(Agricultural Wealth Network) Banana ripening is divided into seven stages: 1. all green; 2. green with very few yellow-green areas; 3. more green than yellow; 4. more yellow than green; 5. only the stalk and neck green; 6. all yellow; 7. yellow with brown spots (plum-blossom speckles).
In the final stage of banana ripening, the peel turns from bright yellow to dull yellow and plum-blossom speckles appear; the plum-blossom speckles are actually disease spots. The anthracnose pathogen that already latently infected the banana fruit in the field develops rapidly in the later stage of fruit ripening when sugar content increases, and symptoms appear. At this point the fruit has already passed its respiratory peak and reached full ripeness. The banana's aroma is at its best and most delicious. The fiber of the peel is also broken down at this time by respiration, and the junction where the stalk connects to the fruit body is extremely prone to breaking, resulting in the fruit dropping from the stem.
