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 More >

Abstract In this paper, midrib of coconut palm leaves (MCL) was investigated for the purpose of development of natural fiber reinforced polymer matrix composites. A new natural fiber composite as MCL/polyester is developed by the hand lay-up method, and the material and mechanical properties of the fiber, matrix and composite materials were evaluated. The effect of fiber content on the tensile, flexural, impact, compressive strength and heat distortion temperature (HDT) was investigated. It was found that the MCL fiber had the maximum tensile strength, tensile modulus flexural strength, flexural modulus and Izod impact strength of 177.5MPa, More >

Abstract Species belonging to the tribe Salicornieae (Chenopodiaceae), called jumes, are rich in salts, reflecting its halophytic nature. The leaf and stem anatomy of Allenfolfea patagonica, Heterostachys olivascens and H. ritteriana were studied. The material, collected in the Salitral de la Vidriera located 30 km from Bahia Blanca (Buenos Aires, Argentina), was fixed, dehydrated, embedded and stained with traditional techniques for plant anatomy. The foliar abaxial epidermis of the three species had papillate cells, while the adaxial one, usually did not. The stomata were sunken in the abaxial epidermis of the three species, and of the adaxial one… More >

Abstract In Egypt there are two different species that are commercially marketed under the same trade name of Neem: one is Azadirachta indica A. Juss., and the other is Melia azedarach L. In this paper, leaf morphological characters (e.g., lamina architecture, stomatography, petiole and blade micromorphology) of both taxa were described and illustrated to aid in the identification and differentiation between the two misidentified taxa. The obtained results concluded that leaf morpho-anatomical characters will not only provide criteria for their correct taxonomic authentication, but would also serve as future standard data for the quality assessment of the pharmaceutical More >

Abstract The photosynthetic characteristics of eight Malaysian Hymenophyllaceae filmy ferns from shady habitats were investigated in this study. Chlorophyll content was highest in Trichomanes meifolium, followed by Cephalomanes obscurum, Hymenophyllum serrulatum, H. denticulatum, H. javanicum, H. acanthoides, H. exsertum and H. blandum, with values ranging from 3.3 to 8.6 mg/g fresh weight. Soluble protein content was remarkably high in H. serrulatum, with values of 53 ± 3.50 mg/g, followed by H. denticulatum, H. acanthoides, T. meifolium and the other species. Protein to chlorophyll ratios in the filmy ferns were low as expected, except for in H. serrulatum, H. acanthoides and H. denticulatum. Chloroplast number 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… More >

Abstract Types of leaf margin serration were investigated in ten species of the genus Hibiscus. Types and frequency of serration varied widely from species to species, from common to occasional to rare. Leaf serration is an important taxonomical feature in Hibiscus. More >

Abstract Micromorphological and anatomical differences in leaf epidermis and stem xylem of Rosa hybrida ‘Lovely Red ‘ (LR) and ‘Rouge Baiser’ (RB), commercially grown in Buenos Aires, Argentina, were examined in the lower half of the terminal leaflet of 5-foliate leaves and in the basal part of stem, respectively. Digital images obtained from SEM and a phase contrast microscope were used with this purpose. Epicuticular wax, which was present on both sides of the leaves, was more abundant in LR than in RB. Stomata were only present on the abaxial side; they were 111 and 129 per… More >

Abstract 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,… More >

Abstract A reliable protocol for plant regeneration of Mullein Nightshade (Solanum donianum Walp.) was developed from in vitro leaf explants. They were cultured on Murashige and Skoog semisolid medium, supplemented with several combinations of zeatin riboside and 1-naphthaleneacetic acid for shoot regeneration. The formulation that originated most shoots per explant was 8.5 μM zeatin riboside in absence of 1-naphthalene acetic acid. Explants with shoots were transferred to Murashige and Skoog medium, with half the normal salt concentration and without plant growth regulators for elongation. Elongated shoots were individualized, and they rooted readily in half-strength Murashige and Skoog More >
