Chlorflurenol as a Fruit-setting Hormone for Gynoecious Pickling Cucumber Production Under Open-field Conditions1

Year: 1983

Type: article

Abstract: Curbiset, a commercial formulation of methyl-2-chloro-hydroxy fluorene-9-carboxylate (chlorflurenol), induced more parthenocarpic fruit on plants of cucumber ( Cucumis sativus L.) from which developing fruits were removed than from plants from which fruit were not removed. Planting at closer spacings yielded more fruit per hectare when chlorflurenol was applied to young plants. However, when sprayed on older plants, spacing did not affect yield. Fruit quality (shape and color) deteriorated when harvesting was delayed beyond 10 days after spraying. Chlorflurenol set a higher percentage of pre-anthesis blossoms early in the season and a greater percentage of post-anthesis blossoms late in the season. Mature blossoms produced larger fruit at harvest than immature blossoms when set with chlorflurenol. Chlorflurenol could be used repetitively to induce a successive fruit set on the same plants for hand-harvest, or sprayed once for a once-over mechanical harvest.
