Abstract
Endogenous levels of ethylene in malformed panicles of mango (Mangifera indica L.) at stages (I) fully swollen buds, (II) bud inception, (III) full grown panicles prior to full bloom and (IV) full grown panicles at full bloom were significantly higher than in healthy panicles.
Likewise, the shoots bearing malformed panicles showed significantly higher levels of ethylene compared with shoots bearing healthy panicles at the four developmental stages.
In a two-year trial, a spray of ethephon (400 ppm) applied at bud inception in February significantly reduced floral malformation and increased yield as compared to all other treatments, including the control.
It was concluded that ethylene plays an important role in the causation of floral malformation in mango.
