Abstract

Olive trees grown in containers received outdoor winter chilling until February 27, 1969, then were moved to a greenhouse where several growth regulators were applied by dipping shoots into test solutions. Flowering was promoted by a growth retardant, B-9 (Alar-85) at 100 ppm, and was inhibited by either GA3 at 25 or 50 ppm or ABA at 10 or 50 ppm; in addition, ABA at 10 ppm stimulated lateral buds-normally flower buds-to grow vegetatively NAA at 50 ppm caused total inhibition of bud development. Cytokinin (6-benzylamino purine) at 50 or 250 ppm had no effect. Under noninductive conditions (trees held in a heated greenhouse throughout the winter months), repeated applications (twice a week for 10 weeks) of IAA, GA3, IAA + GA3, a mixture of GA4 and GA7, or ABA failed to substitute for the low-temperature requirement for flower induction, although GA3 strongly stimulated shoot growth.
