Effects of Benzyladenine and Naphthalene Acetic Acid Applications on Fruit Thinning and Quality of Some Apple Cultivars Grafted onto MM 106 Rootstocks
Abstract
Fruit
thinning is an essential practice to improve fruit size and quality, control
alternate bearing and increase return bloom in the next season. Fruit thinning
is performed by hand or by using some chemicals. In this study, the effect of
chemical thinning, namely two doses of 5 and 10 ppm of Naphthalene Acetic Acid
(NAA) or of 100 and 150 ppm of Benzyladenine (BA) on fruit thinning and some
fruit quality traits Golden Delicious, Red Chief and Granny Smith apple
cultivars grafted on MM 106 clone rootstock in 2015 was tested and compared
with the effect of hand thinning. Chemical treatment was applied after three
weeks of full bloom, while the hand thinning was made to be released a fruit
per cluster on each branch in small fruit period after June-drops. The results
showed that the highest fruit thinning ratio was found in the Granny Smith
cultivars, with 5 ppm (93.80%) and 10 ppm (91.65%) of NAA, 100 ppm (89.88%) and
150 ppm 88.98%) of BA. It can be concluded that the applications of 10 ppm of
NAA and 100 and 150 ppm of BA were found effective for fruit thinning and fruit
quality. Furthermore, the hand thinning application increased the fruit weights
more than all the chemical applications.
