Possible Means to Increase Hass Avocado Fruit Size

A foliar spray of paclobutrazol (250 mg a.i./l) at full flowering increased total yield and the yield of export-size fruit in young Hass trees when compared to the untreated control in two consecutive years. Five Hass-like selections and cultivars (T142, Lamb Hass, Gil, Iriet, 1.14.2) are being evaluated as possible replacements for Hass, and first results on their post-harvest cold storage performance are presented.
