Abstract
The knowledge about growth and nutrient accumulation can help improve fertilizer efficiency in the production of jabuticaba seedlings, which is still carried out in an empirical way. This study aimed at determining the growth and macronutrient uptake in ‘Sabará’ jabuticaba genotypes grown in nutrient solution. The experiment was carried out in a completely randomized design in split plots, with four replications. In the main plots three jabuticaba genotypes (J001, J005 and J012) were cultivated in nutrient solution and six evaluation periods (at 60, 120, 180, 240, 300 and 360 days) in the sub-plots were evaluated. Plant height, root length, stem diameter, leaf area index and dry matter (root, stem and leaves) in each period were evaluated. The accumulation of macronutrients in different plant organs was determined, as well as the accumulation of nutrients as a function of time adjusted to the linear model. The results showed that the cultivation in nutrient solution was efficient in the production of Sabará jabuticabeira seedlings. There was no difference in macronutrient growth and absorption among jabuticaba genotypes grown in nutrient solution. ‘Sabará’ jabuticaba plants accumulated (in mg plant-1) 559 of N, 45 of P, 443 of K, 363 of Ca, 59 of Mg and 82 of S. The distribution of macronutrient accumulations in jabuticaba showed the following order: leaves > stem > roots.
Highlights
Jabuticaba (Myrciaria jabuticaba (Vell) Berg) is a fruit species native to Brazil, belonging to the Myrtaceae family
The management of mineral nutrition in the formation of jabuticaba seedlings is carried out empirically by nurserymen, due to the lack of knowledge regarding the nutritional aspects of this culture
An alternative would be the cultivation in nutrient solutions, once it is an unpublished practice, little used in the production of fruit tree seedlings
Summary
Jabuticaba (Myrciaria jabuticaba (Vell) Berg) is a fruit species native to Brazil, belonging to the Myrtaceae family. The lack of knowledge about production results in the low use of jabuticaba, which contributes to its genetic erosion (WAGNER JÚNIOR et al, 2017). The plants, during several stages of their development (GURGEL et al, 2010) In this context, several studies on mineral nutrition were conducted with fruits such as star fruit (FREITAS et al, 2011; ROZANE et al, 2011a), guava (FRANCO et al, 2007; FRANCO et al, 2008), citrus (SOUZA et al, 2013), pear (SOUZA et al, 2015) and peach (SOUZA et al, 2011). The adequate mineral nutrition of jabuticaba seedlings can contribute to the maximum expression of the genetic potential, as well as to the obtention of healthy and vigorous plants, capable of suggesting the selection and adaptation of genotypes to different soil conditions. The objective of this study was to determine the growth and progression of macronutrient uptake in the initial growth of ‘Sabará’ jabuticaba genotypes cultivated in nutrient solution
