Effect of mepiquat chloride on leaf flushing inhibition in longan

The effect of mepiquat chloride on terminal bud break and growth of panicle in longan was investigated. Seventeen-year-old 'Daw' longan trees were studied. The experiment was designed based on CRD including five treatments i.e., 0, 100, 200, 300, and 400 mg L^‑1. After 7 days all treatments were treated by potassium chlorate (KClO₃). The result revealed that mepiquat chloride treatment had the highest floral emergence while the control gave higher leaf flushing. However, 200, 300, and 400 mg L^‑1 of mepiquat chloride reduced panicle length. There were no effects on the time of terminal bud break and panicle diameter.
