Chemical similarity among domesticated and wild genotypes of peanut based on n-alkanes profiles PAB
Souza,Renata Janaína Carvalho de; Silva,Suzene Izídio da; Oliveira,Antonio Fernando Morais de.
The objective of this work was to analyze the epicuticular n-alkane profile of domesticated and wild peanut genotypes. Foliar epicuticular n-alkanes of four Arachis hypogaea genotypes and two wild species - A. monticola and A. stenosperma - were analyzed by gas chromatography. Chemical relationships between them were evaluated using the Dice coefficient and UPGMA method. Two clusters were formed: one with four A. hypogaea genotypes and the other with the two wild species. There is more similarity between the BR1 and LIGO-PE06 genotypes and between the BRS 151 L-7 and BRS Havana genotypes.

Leaf surfaces of Gomphrena spp. (Amaranthaceae) from Cerrado biome Biocell
Carvalho,Suzane Margaret Fank-de-; Gomes,Misléia Rodrigues de Aguiar; Silva,Pedro Ítalo Tanno; Báo,Sônia Nair.
The leaf structure and micromorphology characterize plant species and reflex its interactions with the environment. Leaf epidermis sculptures aid high transpiration plants on light reflection. The form and distribution of epicuticular wax crystalloids are important to characterize the surface. Aiming to know the micromorphology and the ultrastructure of G. arborescens, G. pohlii and G. virgata, leaves of these Cerrado native species were collected in Brasília, Distrito Federal, Brazil, at the Olympic Center of the Universidade de Brasília and at Reserva Ecológica do Roncador. Leaves of G. globosa, an Indian native species, were also studied for comparison. Leaves were fractionated, fixed and treated for observation under optical and scanning electron...
