ABSTRACT High ammonia (NH4 +) concentration can exert stress on many plants, which causes nutritional disorders and reduction on plant growth. However, depending on the intensity of the stress, it may be attenuated by silicon. In this work, the response of impact of cations and silicon accumulations and plant growth in cultivated papaya plants was investigated under different toxic ammonia concentrations regardless of the presence of silicon (Si). The experiment was conducted at the Universidade Estadual Paulista (UNESP) with papaya seedlings, variety 'Grupo Formosa' (Calimosa híbrida 01), grown in a glass greenhouse, in 1.7 dm3 pots filled with pine and coconut fiber-based substrate. The experimental design was a randomized block design, in a 5 x 2...
