Effect of soil applied paclobutrazol on fruit retention, fruit size, tree yield and tree revenue in Sensation and Tommy Atkins mango.

Soil application of paclobutrazol (applied as Cultar at 0.25 or 2.5 g a.i.) was evaluated as a method to increase fruit size in 2-year-old Sensation and to increase fruit retention in Tommy Atkins mangoes growing in South Africa. Cultar was applied to the soil just prior to the initiation of postharvest flushing. In Sensation, average fruit weight (final fruit size) and tree revenue were increased in direct relation to the rate of paclobutrazol applied. Number of fruits retained and tree yield were not affected. In Tommy Atkins, number of fruits retained, average fruit weight, tree yield, and tree revenue were reduced in direct relation to the rate of paclobutrazol applied. The retarding effect of paclobutrazol on extension or expansion growth was limited in Sensation, but was pronounced in Tommy Atkins.
