Palavras-chave:
biocarvão, composto, fluorescência da clorofila, nutrição mineral, matéria orgânica
Resumo
O maracujá (Passiflora edulis f. flavicarpa) apresenta elevado valor econômico e nutricional, e a fase de viveiro é determinante para o seu desenvolvimento inicial. O objetivo deste estudo foi avaliar a fluorescência da clorofila, o estado nutricional foliar e o crescimento de mudas de maracujá em função de quatro substratos orgânicos: S1 (areia + biocarvão + matéria orgânica), S2 (areia + composto + matéria orgânica), S3 (areia + composto + solo agrícola) e S4 (solo agrícola), sob um delineamento inteiramente casualizado. Foram avaliadas as variáveis fisiológicas Fv/Fm, Φ(II) e ETR, bem como as concentrações foliares de macro e micronutrientes e variáveis de crescimento, cujos dados foram analisados por ANOVA e teste de Tukey (5 %). As mudas cultivadas em substratos S2 apresentaram a maior eficiência fotoquímica (Fv/Fm ≈ 0,79; Φ(II) ≈ 0,44; ETR ≈ 160), enquanto substratos S1 apresentou as maiores concentrações foliares de K, Fe e Zn. A análise de componentes principais explicou 71 % da variabilidade total, associando o substrato S2 a melhor desempenho fisiológico e de crescimento. Conclui-se que substratos contendo composto favorecem a eficiência fotoquímica do PSII, enquanto aqueles que incluem biocarvão estão associados a maior acúmulo foliar de minerais.
