Abstract
Contributing to the domestication process of the Chilean super berry, Aristotelia chilensis, in the present study the effects of genotype and plant nutrition on fruit set, yield, and quality were reported.
Three cultivars of the species were cultivated in pots and treated with complete fertilization, potassium, calcium or boron deficiency and without fertilization.
Genotypes determined fruit set, yield, berry weight, diameter, seed number, ripening, soluble solids, percentage of shriveled and cracked fruit, as well as plant height.
Concerning the effect of nutrition treatments, maqui berries of non-fertilized plants exhibited higher antioxidant capacity (ORAC) than fertilized ones.
The potassium content of fruit was significantly correlated with K, Ca, and B fertilization.
Fruit growing in fertilized Perla Negra plants weighed more than those harvested from non-fertilized ones but had a problem with cracking.
Berries of non-fertilized plants of Morena had more soluble solids than complete fertilized ones.
Fruit set of Luna Nueva was affected by boron deficiency.
Most of the fruit quality factors studied are mainly determined by the genotype.
