Abstract

The tomato crop has social, food, and economic importance both in Brazil and internationally for generating high employment opportunities in the productive sector and offering high nutritional value of the fruits. Given the importance of this tomato culture, there is a constant search for improved varieties that meet the needs of producers in the processing industry. The objective of this study was to characterize strains of the industrial tomato in the absorption of macronutrients and micronutrients, in level of chlorophyll content in leaves, in productivity, and in uniformity of maturation fruits. The experiment was conducted in 2014 in the experimental area of the Federal University of Goiás in Goiânia. The design was a randomized block with 25 treatments (22 lines and three commercial hybrids) and four replications. We evaluated the chlorophyll content in leaves, macronutrient content, foliar macro and micronutrient content, fruit yield, and uniformity of maturation. The lineages CVR 1, CVR 3, CVR4, CVR 5, CVR21, and CVR 22 have high productivity, as well as being uniform in maturation. The lineages CVR 2, CVR 5, CVR 7, CVR 8, CVR 9, CVR 10, CVR 11, CVR 12, CVR 13, CVR 14, CVR 15, CVR 16, CVR 17, CVR 18, CVR 19 and CVR 20 are uniform in maturation. The lines have different potentials regarding the absorption of P, K, Ca, Mg and Zn. There is a positive correlation between the chlorophyll content and the amount of nitrogen present in the leaves.
