Abstract:The objective of this research was to determine the effects of chemical thinning with α-naphthaleneacetic acid (NAA) and nitrogen (N) fertilization, as well as their interaction in relation to fruit set and physical properties of apple cv. Golden Delicious Reinders®. Nitrogen rates used were 30 and 60 kg•ha −1 N applied at the pink bud stage. NAA for fruit thinning was applied at the rates of 10, 12 and 14 µl•l −1. Fruit set was increased by increasing the amount of N applied while the efficacy of NAA for frui… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
