Abstract In this work, we investigated aroma volatiles emanated by dry roots, stems, leaves, flowers, and fruits of Cardaria draba (L.) Desv. growing wild in Tunisia and its aerial part essential oils (EOs) composition. A total of 37 volatile organic compounds (96.7%–98.9%) were identified; 4 esters, 4 alcohols, 7 hydrocarbons, 12 aldehydes, 5 ketones, 1 lactone, 1 organosulfur compound, 2 organonitrogen compounds, and 1 acid. The hydrocarbons form the main group, representing 49.5%–84.6% of the total detected volatiles. The main constituent was 2,2,4,6,6-pentamethylheptane (44.5%–76.2%) reaching the highest relative percentages. Forty-two compounds were determined in the two fractions of EOs, representing 98.8%… More >

Abstract The aim of the present work was to analyze the foliar anatomy in lamina transverse section an in epidermis superficial view of Mnesithea selloana. Epidermic preparations and transections were carried out of the medium leaf part of sterile innovations that were conditioned and observed with optic microscope (OM) and scanning electron microscope (SEM).The histofoliar characteristics observed were: epidermic, intercostal, subsidiary, suberose, silicea and bulliform cells; and also guard cells, hairs, waxes, mesophylls, Kranz sheath, vascular bundles, sclerenchyma, colourless parenchyma and leaf margin. Epidermic observations showed that M. selloana presents a panicoid type epidermis presenting silicic cells as halteriforme, longer than… More >

Abstract The goals of this study were (1) to make a careful study of the foliar epidermis of Grindelia cabrerae var. cabrerae, Solidago chilensis y Wedelia buphthalmiflora, native Asteraceae from Argentina which have ornamental potential, and (2) to determine variables that indicate adaptation to xeromorphic environments. Five adult leaves from five plants were selected from each population. All the material was fixed in FAA. The epidermis of both foliar sides were macerated in hypochlorite of sodium, and obtained by scraping. They were stained with safranine and mounted in water-glycerine (1:1). From each slide, five fields were chosen and frequency of the… More >
