1. Cuticular n-alkane in leaves of seven Neotropical species of the family Lecythidaceae: a contribution to chemotaxonomy
ABSTRACT Biosynthesized from very long-chain fatty acid wax precursors, n-alkanes make a valuable contribution to the taxonomy of plants. The alkane components of foliar epicuticles of seven Neotropical species of Lecythidaceae were investigated: Bertholletia excelsa, Cariniana legalis, Couroupita guianensis, Eschweilera alvimii, Eschweilera ovata, Gustavia

5. Cuticle of 'Gala' and 'Galaxy' apples cultivars under different environmental conditions
This study aimed to analyze the cuticle thickness and pattern of epicuticular wax deposition in 'Gala' and 'Galaxy' apple cultivars (Malus domestica Borkh,) from three Brazilian producing areas: Vacaria (RS), Fraiburgo (SC) and São Joaquim (SC) with altitudes of 971, 1,048 and 1,353m, respectively. Harvested fruit were kept under two storage conditions: reg

6. Ecophysiological responses to drought and salinity in the cosmopolitan invader Nicotiana glauca
Nicotiana glauca, a shrub native to southern South America, is widely distributed in the Americas, from Patagonia to the USA, from zero up to 3,700 m; it rapidly invades disturbed environments. In Venezuela, it has been reported from zero up to 2,000 m growing in contrasting conditions of relative humidity, temperature, rainfall, and salinity. In order to ga

7. Anatomical and physico-chemical characteristics of fruits of apple trees (Malus domestica Borkh.) and their relations to lenticel breakdown / Características anatômicas e físico-químicas de frutos de macieira (Malus domestica Borkh.) e sua relação com a lenticelose
The aim of this study was to describe anatomical and physico-chemical characteristics of apple fruits (Malus domestica Borkh.) Gala and Galaxy grown in three different altitudes, seeking to correlate them to the physiological disorder known as lenticelose (lenticel breakdown), characterized by the darkening of lenticels and the occurrence of brownish depress

10. Estudo bioquimico e da estrutura foliar de plantulas do jatoba da mata (Hymenaea courbaril L.) e do cerrado (Hymenaea stigonocarpa Mart.) expostas a concentração elevada de C O IND. 2 / Structural and biochemical study of leaves of jatobas Hymenaea coutbaril L. and H. stigonocarpa Mart. exposed to elevated concentrations of carbon dioxide atmosphere
The atmospheric concentration of carbon dioxide (CO2) increased from 280 ppm, during the Industrial Revolution period, to about 370 ppm in the nowadays. It is continuing to increase about 1.8 ppm per year. The effect of this rise in CO2, which is leading to global warming have attracted considerable attention, generating reports on how these changes can affe

11. Ferrugem asiática da soja: métodos de preservação dos urediniósporos e fatores relacionados à infecção do hospedeiro / Asian soybean rust: methods for uredospores preservation and factors related to host infection
Soybean is the agricultural crop with the largest planted area in Brazil. The country stands out in the world scenario as the second-largest producer and exporter of this oilseed crop. The Asian rust (AR), caused by the fungus Phakopsora pachyrhizi, is one of the most serious phytosanitary problems of soybean in Brazil, especially because no cultivars exist
