Abnormal fruit development
Peppers that are exposed to high temperatures (32˚C day, 21˚C night) for several days while flower buds are forming can develop blocky fruit with extra segments (locules). Exposure to cool conditions (15˚C day, 5˚C night) during flowering may result in abnormally flattened, seedless peppers with thin walls, which may be pointed at the blossom end.
Adverse conditions during pollination may also results in other fruit deformities, such as openings in the fruit wall.
