NUTRIMENTAL COMPOSITION OF BIOMASS AND CONDUCTIVE TISSUE IN HABANERO PEPPER (Capsicum chinense Jacq.)

Abstract

The nutritional status of plants can be determined through analysis in dry tissue or cell extract. The first is the most commonly used, but the second is faster, allowing decisions promptly. In habanero pepper is unknown whether both analytical connections exist. Therefore, the objective of the study was to determine the possible overlap between the two analytical ways. For this, samples were collected at 50, 75, 100 and 120 days of development of biomass and cell extract of plant tissues drivers Creole. We determined the contents of N, P, K, Ca, Mg, Cu, Fe, Zn and Mn and assessed the interactions between them. It was also the relationship between nutrients, the curve of accumulation and the efficiency of absorption of NPK. The results showed high correlation r = 0.9 on biomass and extract cellular mobile plant nutrients (N, P and K), a correlation r = 0.8 nutrient mobility intermediate (Zn) and a correlation r = 0.6 nutrient low mobility (Ca and Mn). Fe was the only one that showed no significant relationship with any nutrient. The relationship between nutrients in biomass provided more meaningful responses to the nutrients in the cell extract. Curves suggest that accumulation of NPK 130-120-160 fertilization of N, P2O5 and K2O respectively, should be increased by 63% for N, halved the P2O5 and keep the dose of K2O.
