ABSTRACT: The
aims of study were to evaluate growth and characterize the visual symptoms of
macronutrient and micronutrient deficiencies in mangosteens. The seedlings were
cultivated in nutritive solution containing all required macronutrient and
micronutrients and in solutions with omission of N, P, K, Ca, Mg, S, B, Cu, Fe,
Mn, and Zn, using the missing element technique. The experimental design was
completely randomized with five replicates and twelve treatments. Symptoms of
nutrient deficiency were accompanied by photographic records and described from
beginning until complete definition, in which the plants were collected. Growth was evaluated through of dry mass
production and nutrient contents. Nutrients omissions resulted in morphological
alterations, characteristic symptoms of nutritional deficiency, promoted the
reduction in dry mass production in plant, in which the Fe was most limiting,
followed by N, and S. Macronutrients and micronutrients contents, without
deficiencies (complete treatment) and deficient in mangosteen leaves were
respectively: N (16.4 and 12.5 g kg-1); P (1.1 and 0.2 g kg-1); K (10.2 and 8.1 g kg-1); Ca (6.7 and 1.9 g kg-1); Mg (1.1 and 0.1 g kg-1); S (3.0 and 2.2 g kg-1); B (20 and 16 mg kg-1); Cu (7 and 3 mg
kg-1); Fe
(266 and 86 mg kg-1); Mn
(58 and 17 mg kg-1). The
decreasing order in appearance of visual symptoms of deficiency was N > S > K > B
> Ca > P > Mg > Mn > Cu > Zn.
