4 Pepper morphology
Pepper
Taxonomy
Dicotyledon Family: Solanaceae Genus and species: Capsicum annuum Related species: tomato, potato, nightshade
Pepper
Domestication
Endemic to tropical and subtropical America Evidence in Mexico earlier than 5000 BC Spread throughout the world by Spanish and Portuguese traders
5 Pepper
Fruit set
Temperature sensitive Pollen death and abscission >90 or <60 Optimum set at 70-80 Drought stress causes flower drop Long-term temps higher than 95 cause abnormal fruit growth
Pepper
Production Problems
Subject to many of the diseases and insect problems common to tomatoes Pest problems do not tend to limit production in warm climates
Pepper
