Palavras-chave:
antocianinas, proporcionalidade biométrica, qualidade de Dickson, índice de robustez, taxa de crescimento
Resumo
A Euphorbia cotinifolia L. é uma planta ornamental de importância econômica devido à cor vermelho-púrpura de sua folhagem. Foi avaliado o efeito da radiação solar, do tipo de substrato e do ambiente no crescimento e qualidade ornamental de plantas de E. cotinifolia, propagadas a partir de estacas semi-lenhosas. Dois experimentos foram conduzidos de junho de 2022 a março de 2023, em Tetela de Ocampo e Huitzilan de Serdán, Puebla, México. Cada experimento tinha 20 tratamentos. Os experimentos tinham um projeto fatorial 2x5x2; o fator 1 era ambientes de crescimento, seus níveis: clima temperado (STC) e subtropical (SHC). O fator 2 foi a irradiância solar, seus níveis: 80, 240, 347, 394 e 571 µmol.m-2.s-1. O fator 3 foi o tipo de substrato, seus níveis: areia de rio com turfa (AT) e solo de floresta com perlita (SP). Aos 243 dias após o enraizamento, os valores mais altos foram: 32,98 cm para o crescimento do broto terminal, 4,80 mm.dia-1 na taxa de crescimento, 1,76 no índice de robustez, 1,32 no índice de Dickson. A concentração máxima de antocianina foi de 4,94 mg.g-1 nas folhas vermelho-púrpura. Os valores mais altos e a cor vermelho-púrpura da folhagem (indicador de qualidade) ocorreram quando as plantas foram cultivadas em substrato AT, a 571 µmol.m-2.s-1 no clima SHC. Conclui-se que num clima subtropical, as plantas se desenvolvem com melhor qualidade; recomenda-se como substrato areia de rio com turfa e exposição a altas intensidades de luz.
