|Description: ||Bombacopsis glabra is an ornamental tree used to restore degraded areas and landscape composition. The nutritional deficiency symptoms presented by this species allows the identification and correction in growing plants. The objective of this study was to identify the visual symptoms of nutrient deficiency in seedlings of Bombacopsis glabra. The research was in completely randomized design with four repetitions and nine treatments, being a complete treatment (without omission of nutrients) and the other with the omission of N, P, K, Mg, S, Fe, B and Zn. Excepting omission of the treatment with K, in all others, it was observed symptoms. Among the diagnosed symptoms, chlorosis appeared as a characteristic symptom in the treatment of N, Mg, S and Zn, only alternating the intensity and the affected organs. The omission of boron induced necrosis and blight on the leaves. The omission of K resulted in lower seedling dry mass; however they did not show visual symptoms, which may be associated with a stock of K in the seed sufficient for early development of seedlings.|
