In vitro propagation of Dendrobium macrostachyum, a threatened and endemic species was achieved through nodal explants. The nodal explants were cultured on Murashige and Skoog (MS) basal medium and MS medium supplemented with N6-benzyladenine (BA-2.22, 4.44 and 8.88 microM), Kinetin (KN-2.32, 4.65, and 9.29 microM) and Coconut water (CW, 5, 10 and 15%) individually or in combination with 2.69 m...

Anther primordium of Malaxis muscifera (Lindl.) Kuntze initiated as a homogenous mass of meristematic cells is surrounded by protoderm. Two thecae are oriented towards the labellum, each of them consisted of a mass of archesporial cells. The hypodermal layer of sporogenous cells divide periclinally to form an endothecial, a middle layer and a tapetum. Pollen mother cells formed different types ...

The fruit of the plum tree (Prunus salicina Lindl.) has been used as a traditional medicinal food in humans to enhance immunity against infectious agents and to treat cancers. However, limited information exists on the mechanisms responsible for its immune enhancing properties. In this study, the immunostimulatory effects of a methanol extract of plum fruit following methanol evaporation and di...

BACKGROUND AND AIMS The two closely related subtribes Bifrenariinae Dressler and Maxillariinae Benth. are easily distinguished on morphological grounds. Recently, however, molecular techniques have supported the inclusion of Bifrenariinae within a more broadly defined Maxillariinae. The present paper describes the diverse labellar micromorphology found amongst representatives of Bifrenariinae (...

The orchid genus Brachystele Schltr. (Orchidoideae, Cranichideae, Spiranthinae) comprises 20 species distributed from Mexico to Argentina, with 10 found in Brazil. Anatomical studies of Orchidoideae Lindl. have been scarce, and the anatomy histochemistry are still largely unknown. In this study, we conducted a characterization vegetative organs B. guayanensis (Lindl.) using standard anatomical ...

Lupinus polyphyllus Lindl is a perennial herbaceous plant widely distributed in the Northeastern states of USA, Canada, Europe, Argentina and New Zealand. This on Kola Peninsula. L. contains alkaloids, main which are lupanine, lupinine, sparteine. The aim study was to determine cytotoxicity aqueous extracts seeds studied their effect biomass growth by Allium-test method. It found that solutions...

Biodiversitas 24: 2577-2586. Members of the are ecologically diverse, covering human plant pathogens, saprobes, endophytic fungi economically important plants. The role FSSC on tropical orchids, however, has received...

ethanolic crude extract of i. imbricata lindl. (iridaceae) was subjected to column chromatography on silica gel with varying portions of meoh: chcl3. nigicin (irisolone) was isolated and its identification carried out by ir, uv, ms, 1-d and 2-d nmr spectroscopy.
