Due to the lack of scientific knowledge for the use of substrate and best fertilizing method in the growth of Araucaria excelsa, it is crucially important to find the most appropriate planting substrate and fertilizing method. The effect of conventional fertilizing method and the application of Fe nanofertilizer were studied on the growth of A. excelsa in which six fertilizing methods and three...

Stem bark of Hippocratea excelsa afforded six pentacyclic triterpenes, five oleanane and one ursane types. They were identified as 11beta,21beta-dihydroxy-olean-12-ene-3-one (2), 3alpha,11alpha,21beta-trihydroxy-olean-12-ene (3), 3alpha,21beta-dihydroxy-11alpha-methoxy-olean-12-ene (4), 3alpha,21beta-dihydroxy-olean-9(11),12-diene (5), 3alpha,21beta-dihydroxy-olean-12-ene (6) and 3alpha,21beta-...

This paper reports the first occurrence of Lasiodiplodia theobromae in Brazil nut (Bertholletia excelsa). Cankers were found on branches 3-year-old plants Belém, Pará, Brazil. The symptomatic displayed reddish vascular lesions. pathogen was identified using morphological and phylogenetic analyses. Koch’s postulates fulfilled, confirming L. nut.

Figure 1. Antigenotoxic activity of Borago officinalis plant material: (a) blue flowered (BF) and (b) white flowered (WF) plant material expressed as mutation frequency corrected to control. Strength of inhibition on the capability of H2O2 (0.12 M) to induce mutated cells is also shown (Inhibition Percentage in brackets). White columns correspond with tested concentrations of simple treatments,...

There is limited information on intra-annual plasticity of secondary tissues of tree species growing under different environmental conditions. To increase the knowledge about the plasticity of secondary growth, which allows trees to adapt to specific local climatic regimes, we examined climate-radial growth relationships of Norway spruce [Picea abies (L.) H. Karst.] from three contrasting locat...

The article presents the results of a research Project aimed at making a characterization of Cognitive Styles (CS) in the dimension of field sensibility-independence, of a sample of 126 Industrial Design students of the Jorge Tadeo Lozano University (JTLU) in Colombia, 90,47% of them come from the central Andean region. The guiding approach of our project is the Theory of Psychological Differen...
