Abstract

The objective of this study was to evaluate the effect of different nutrient solutions on the development and concentration of micronutrients in guava cuttings. Two cultivars - Paluma and Século XXI - and four nutritional solutions were evaluated, using a factorial scheme (2x4) with three repetitions. At 90 days of hydroponic culture, dry mass and micronutrient nutrition in the cuttings were evaluated. The Paluma guava cuttings displayed greater development and nutritional requirements for boron, iron and manganese, as compared to cultivar Século XXI. The studied nutrient solutions did not affect accumulation, absorption or use efficiency of micronutrients in guava cuttings, except for copper and zinc, regardless of cultivar. (AU)
