“…Calcium omission influence blooming since this nutrient affect cell differentiation and elongation, being necessary for cell division and formation of cell wall cannot be substituted in their function by other ions (Costa et al, 2017;González-Fontes et al, 2018;Kirchhelle et al, 2019). For marigold, Ca omission also affected blooming (Coelho et al, 2011) but not in Etlingera elatior (Frazão et al, 2010), showing some antagonistic results.…”

Knowledge about the nutritional aspects of calla lily, an important species for the floriculture industry, is essential for quality on cultivation. As there are variations in the symptoms of nutritional deficiencies among species, it is necessary to study the development of plants and their nutritional status when grown under nutrient omission. Thus, the aim was to evaluate the development of calla lily plants and identify the levels of nutrients and their interactions in cultivation conditions under nutritional deficiency. The treatments consisted in the use of the complete nutrition solution and the omission of N, P, K, Ca, Mg, S, Fe, B, and Mn, separately. The experimental design was in randomized block design with four replications. The omissions of P, S, Ca, K, N, and B have influenced the plant development providing lower production of leaves and in small size, reduction on shoots production and less leaves emitted by the shoots, besides a lower values of dry matter. Among these nutrients, the deficiencies that most affected the growth and quality of calla lily plants development were N, B and Ca. The B and N deficiency inhibited the flowering and the absence of S and K provided inflorescences production with lower quality, besides malformation. The main interactions that occurred were increasing in the content of K (leaves), Fe (leaves) and Mn (leaves and inflorescences) in the absence of Ca. In the absence of Mg there was an increase in Ca (leaves, rhizomes, and inflorescences), Zn (leaves and roots) and Fe (rhizomes). It can be concluded that the nutritional deficiencies that most affected the production of inflorescences in calla lily were those of B, N, P, K, Ca, and S and the main nutritional interactions occurred in the absence of Ca with an increase in K, Fe and Mn and an increase in Ca, Fe and Zn in the absence of Mg.

Multiple nutritional deficiencies are considered one of several factors that can induce doubt in the diagnosis based only in visual symptoms, because it makes identification more difficult. The aim of this work was to evaluate the development of Zantedeschia and the morphological changes resulting from nutritional disorders caused by multiple and simple nitrogen and phosphorus deficiency in plants grown in nutrient solution. Zantedeschia plants were grown for a period of eight months in a complete Hoagland and Arnon (1950) solution, with nitrogen (-N) omission, with phosphorus (-P) omission, with nitrogen and phosphorus (-NP) omission, and also nutrient solution with N and P at concentrations of 25, 50 and 75%, totalizing 7 treatments, with 4 replicates in a completely randomized experimental design. At the end of the experimental period, plant height, number of emitted leaves, leaf size, number and mineral composition of shoots were assessed. The omission of nutrients both in simple and multiple forms affected plant development. The highest shoot formation occurred in plants grown in solution and with 50% of the concentration of NP. The mineral composition of macronutrients present in leaves and shoots of plants was influenced by multiple deficiencies of N and P.Index terms: Zantedeschia aethiopica, multiple omission, macronutrient, cut flower, calla lily. RESUMOA deficiência múltipla é considerada um dos vários fatores que pode induzir dúvidas na diagnose baseada apenas na sintomatologia, pois torna a identificação mais difícil. Assim, objetivou-se avaliar o desenvolvimento de copo-de-leite (Zantedeschia aethiopica) e as alterações morfológicas decorrentes da desordem nutricional provocada pela omissão múltipla e isolada de nitrogênio e fósforo em plantas cultivadas em solução nutritiva. O copo-de-leite foi cultivado por um período de 8 meses em solução de Hoagland e Arnon (1950) completa e com omissão simples de nitrogênio (N), de fósforo (P) e múltipla de NP e, ainda, solução nutritiva com NP nas concentrações, na proporção de 25, 50 e 75%, totalizando 7 tratamentos, com 4 repetições e delineamento experimental inteiramente casualizado. Ao final do período experimental foi avaliada a altura das plantas, o número de folhas emitidas, número de brotos e a composição mineral da parte aérea. A omissão de nutrientes tanto na forma simples quanto múltipla afetou o desenvolvimento das plantas. A maior formação de brotos ocorreu em plantas cultivadas em solução completa e com 50% da concentração de NP. A composição mineral dos macronutrientes presentes em folhas e brotos das plantas foi influenciada pela deficiência múltipla de N e P. Termos para indexação:Zantedeschia aethiopica, omissão múltipla, macronutriente, flor de corte, calla lily.
