Abstract

Flowering pattern and seed development were studied to determine the optimum time of harvest for lettuce seed production. Lettuce plants showed the highest flowering peak at 72 days after transplanting (138 flowers/plant), 91 days after transplanting (226 flowers/plant) and 94 days after transplanting (205 flowers/plant) in leaf lettuce (cv. Grand Rapids) , butterhead (cv. Summer Queen) and head lettuce (cv. Great Lake 659), respectively. Seed of these three lettuce types reached their physiological maturity in 12 days after anthesis.
