Title: Flower bud thinning in ‘Rojo Liso’ cactus pear
Abstract: SummaryThe export of cactus pear fruit from Mexico has increased over the last decade, with growing consumer demand for larger and higher quality fruit. Growers are concerned that yields decrease when fruit thinning is used to increase fruit size. Our objective was to assess the effects of flower bud (FB) thinning on the pre-harvest and post-harvest attributes and yields of ‘Rojo Liso’ cactus pear (Opuntia ficus-indica) fruit. The experiments were conducted in 2005 and 2006. The treatments used were: 1) no thinning, considered as the control; 2) thinning every second bud (T1); or 3) thinning two out of every three buds (T2). Marketable fruit (having an equatorial diameter > 5 cm) in the thinned treatments increased compared to the unthinned controls in both seasons. Thinning did not reduce fruit yield. Fruit quality was similar among treatments, both at harvest and after storage, except for the soluble solids concentrations which were higher in both the T1 and T2 treatments in 2005. Fruit weight loss in storage was similar among treatments. Flower bud thinning can therefore be recommended for commercial use.
