Abstract

Abstract The amount of nutrients accumulated and distributed in young jabuticaba trees are not yet well known. The aim of this work was to verify biomass production, nutrient accumulation and distribution in ‘Paulista’ and ‘Sabará’ jabuticaba seedlings. The experiment was conducted in greenhouse and seedlings were propagated by seeds and transplanted after 150 days into pots containing perlite and cultivated for 450 days in nutrient solution. Nutrient accumulation and distribution in the different plant organs (root, stem and leaves) were evaluated every 90 days. The mean total nutrient accumulation of ‘Paulista’ and ‘Sabará’ seedlings at 450 days were: N (706 and 611), P (81 and 62), K (541 and 409), Ca (488 and 424), Mg (66 and 54) and S (93 and 92) in mg plant-1 and Cu (1578 and 1635), Fe (20887 and 19652), Mn (13975 and 13434), Zn (4921 and 4048) and B (642 and 764) in µg plant-1, respectively. ‘Paulista’ and ‘Sabará’ jabuticaba seedlings presented the following tendency of nutrient accumulation and distribution among organs: leaf > stem > root. Thus, this work can be a useful reference for studies on the fertilization management in jabuticaba seedlings.

Highlights

Fruit tree native to Brazil and inserted in the Atlantic Forest Biome, jabuticaba belongs to the family Myrtaceae, genus Plinia
It was observed that nutrient solution, hydroponic cultivation conditions and experiment execution did not limit the development of jabuticaba seedlings, which resulted in positive the relative nutrient absorption rates (TARN) values (Table 2)
The highest macronutrient absorption rates (TARN) in the whole plant were observed in the period of 90 - 180 days, except for N, which had the highest absorption in the period of 180-270 and 270-360 DAT, respectively, for ‘Paulista’ and ‘Sabará’ cultivars

Summary

Introduction

Fruit tree native to Brazil and inserted in the Atlantic Forest Biome, jabuticaba belongs to the family Myrtaceae, genus Plinia. ‘Paulista’ cultivar yields large and very productive tree, and its fruits are large in size, with coriaceous bark and is recommended for the production of liqueurs and jellies. Soil is considered a complex medium for studies related to mineral nutrition. In this way, the use of simpler artificial means, such as cultivation in nutrient solution, allows better control of nutrient proportions and evaluation of plant nutrition (FRANCO & PRADO, 2006).
