    Contribution to knowledge of foliar anatomy on Mnesithea selloana (Hack.) de Koning & Sosef (Andropogoneae-Panicoideae-Poaceae)

    Moya ME1,2, AA Galussi1,2, MJ Gómez1,2, FG Marchese1,2

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 176-183, 2015, DOI:10.32604/phyton.2015.84.176

    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 >

    Mnesithea selloana: morphology of sinflorescence, maturity and caryopsis quality

    Galussi AA1,2, ME Moya1,2, LR Zimmermann1, FG Marchese1,2, YG Gillij1,2, F Torres1,2

    Phyton-International Journal of Experimental Botany, Vol.81, pp. 255-260, 2012, DOI:10.32604/phyton.2012.81.255

    Abstract Mnesithea selloana (known as cola de largarto, teyú ruguay) is a spring-summer-fall species that flowers and fructifies in that period; it has good forage quality, and it is in danger of extinction in the natural grasslands at the study region. The objectives of this work were to study the sinflorescence morphology, and the maturity and quality of the caryopsis to know its reproductive aspects in relation to the dissemination of this especies in grazing areas. The sinflorescence was studied in two plants during a period of 45 days, between October and December 2010, within an experimental field of the UNER… More >

    Stem and root anatomy of Mnesithea selloana (Hack.) de Koning & Sosef

    Moya ME1,2, AA Galussi1,2, N Sattler2, MS Fontana2, YG Gillij1,2

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 231-235, 2018, DOI:10.32604/phyton.2018.87.231

    Abstract The objective of this study was to analyze the anatomy of stems and roots of Mnesithea selloana. Free hand cross sections were made from fresh material of reproductive stems and adventitious roots; they were colored with safranin and mounted on glycerin jelly. Observations were made using an Olympus CH2 light microscope and photographed. In cross section, the stems were circular towards the distal end of the synflorescence and semicircular toward the proximal end, and have two ribs. A uniseriate, continuous epidermis presenting a smooth and thick cuticle and no hairs was observed. Parenchyma cells increased in size towards the pith;… More >
