“…Boron deficiency, in general, reduces root growth (Lima Filho and Malavolta, 1997;Viegas et al, 2004) and in the coconut palm tree, production of total roots is reduced by 30% and of thin roots by 48% ( Pinho et al 2008a), Sobral (1998), Broschat (2005, and Santos et al (2003) observed that boron deficiency also damages the plant aerial part ,which produces less expanded young leaves with signs of blighted, necrotic, and corky areas. The primary symptoms of B deficiency in coconut trees are leaflet tip truncation, leaf crumpling or distortion, and failure of the spear leaf to open normally.…”

Boron, one of the micronutrients frequently found in low levels in tropical soils affects nutrition and productivity of coconut palm trees essentially cultivated in tropical climates. The objective of this research study was to evaluate the effect of boron on the nutritional status of the plant and its productivity when artificially applied to the culture soil. The experiment was carried out in a four year old, artificially irrigated, dwarf coconut palm orchard in Brazil, between January, 2005 and October, 2006. The soil was a red yellow Latosol (B: 0.18 mg dm -3 ). The treatments consisted in the application of five boron dosages: zero, 1, 2, 4, and 6 kg ha -1 . In the field, the treatments were arranged according to a completely randomized block design, with four replications. Boron (borax) dosages were applied in equal halves directly into the soil in the months of January and February of 2005. Boron concentration in the soil and plant and plant productivity were evaluated. The higher palm tree production was associated to levels of 0.6mg dm -3 of B in the soil and 23.5mg kg -1 in leaves. Ninety five percent of palm trees maximum production was obtained with the use of a boron dosage of 2,1kg ha -1.

“…Já o menor teor de K foi encontrado nas plantas cultivadas em solução nutritiva. Pinho et al (2008), estudando deficiências nutricionais em coqueiro anão, verificou que plantas deficientes de B apresentaram altos teores de K, corroborando os dados encontrados neste trabalho.…”

O objetivo deste estudo foi avaliar os teores e acúmulos de macronutrientes em gengibre ornamental sob deficiências nutricionais de macronutrientes e boro. O experimento foi realizado na casa de vegetação do Departamento Ciência do Solo, na Universidade Federal de Lavras (MG). As plantas foram propagadas via sementes e germinadas em bandeja com 72 células individualizadas, usando vermiculita. Trinta dias após a germinação, as mudas foram transferidas para solução nutritiva completa. Após 60 dias de adaptação, foram transplantadas em vasos de 6 litros e aplicaram-se os tratamentos. O delineamento foi inteiramente casualizado (DIC) com quatro repetições e seis tratamentos: Solução de Bolle-Jones (controle), solução completa com exceção de N, solução completa com exceção de P, solução completa com exceção de K, solução completa com exceção de Ca, solução completa com exceção de Mg, solução completa com exceção de S e solução completa com exceção de B. As plantas foram monitoradas quanto ao aparecimento dos sintomas de deficiência nutricional, por 180 dias. A colheita foi realizada separando-as em folhas, hastes, rizoma e raízes. As deficiências nutricionais causam alterações nos teores e nos acúmulos das diferentes partes da planta. Os teores de P, K Ca, Mg e S encontrados nas hastes de gengibre ornamental no tratamento completo são (g kg-1): 8,11; 26,40; 5,51; 4,13 e 1,84. Os teores de P, K Ca, Mg e S encontrados no rizoma de gengibre ornamental no tratamento completo são (g kg-1): 6,30; 23,0; 5,63; 3,59 e 3,03. Os teores de P, K Ca, Mg e S encontrados nas raízes de gengibre ornamental no tratamento completo são (g kg-1) 15,86; 14,40; 394; 4,14 e 4,96.

“…Fernandes et al (2013), studying nutritional deficiencies of macronutrients and sodium in peach palm seedlings, observed that seedlings deficient in P showed an increase in the length of the primary roots and a smaller amount of root hairs. B deficiency, in turn, can reduce the production of total and thin roots, cause thickening of the roots and short branches (Lima Filho and Malavolta, 1997;Salvador et al, 1999;Pinho et al, 2008). Well-developed roots represent an increase in the dry matter production capacity of plants, as they are responsible for the water and nutrients uptake, besides the storage of carbohydrates and proteins responsible for the production and continuity of the plant.…”

Environmental conservation and regeneration actions must consider plant species that add value by restoring structural and functional aspects of the ecosystem. The forest species, Peltophorum dubium, has several characteristics that make its use viable in projects of restoration of degraded areas, making it necessary to study the species' responses to different cultivation environments. Thus, 500 seeds were selected and sown in vermicompost substrates prepared with different proportions of cattle rumen content (CR) and sugarcane bagasse (SB) (V1 - 60% CR x 40% SB / V2 - 50% CR x 50 % SB / V3 - 40% CR x 60% SB / V4 - 70% CR x 30% SB) and in an commercial substrate (Plantmax®). At 79 days after sowing, 20 seedlings per treatment were removed; they were weighed and measured, resulting in growth, dry matter, and vigor data. The vermicompost substrates were sent to the chemical analysis laboratory to determine their chemical composition. The data were submitted to normality analysis. Analysis of variance was performed for normal data and the Kruskal Wallis test for data that did not show normality. The means or medians were compared using the Tukey test at a 5% probability level. Based on the results related to the growth and vigor of P. dubium seedlings, it is possible to state that the productive potential of the species was higher in the vermicompost substrates.
