A NEW SECTION OF ANTHURIUM, SECT. DECURRENTIA - REVISION OF THE ANTHURIUM DECURRENS POEPPIG COMPLEX IN AMAZONIA

A reassessment of Anthurium species with palmately divided leaves, and a reinterpretation of Anthurium section Dactylophyllium (Araceae)

A reappraisal is made of the Anthurium Schott species with palmately divided leaves with 3 or more segments free to the base (i.e. palmatisect leaves), previously recognized as section Dactylophyllium Schott (Engler), as well as those species with 5 or more segments united at the base (i.e. palmatifid leaves), formerly placed in section Schizoplacium Schott (Engler). New molecular data indicate...

Differentiated Microelement Content in Anthurium (anthurium Cultorum Birdsey) Leaves*

The main objective of the study was to determine the nutritional status in terms of the content of microelements, such as iron, manganese, zinc, copper and boron in several standard cultivars of anthurium (Anthurium cultorum Birdsey) called Baron, Choco, Midori, Pistache, President and Tropical. The plants were grown in expanded clay (ř 8-18 mm) using drip fertigation with standard nutrient for...

Micropropagation of Anthurium spp

Plant regeneration of Anthurium andreanum cv Rubrun

To establish an efficient regeneration system for Anthurium andreanum cv Rubrun, seeds from plant spadixes were germinated on a medium supplemented with 2.2 μ M BA. After 2 weeks, 74% of the seeds germinated and four weeks later, micro-cuttings from these plantlets were subcultured on a medium containing 4.4 μ M BA and 0.05 μ M NAA. On average, 3.6 shoots per explant were obtained. Four weeks o...

Somatic embryogenesis in anthurium (Anthurium andraeanum cv. Eidibel) as affected by different explants

This study establishes a protocol for the induction of somatic embryogenesis in Anthurium andraeanum cv. Eidibel. The experiment was arranged in a completely randomized 5 x 5 x 5 factorial design using five explant types (whole leaves, half leaves; petiole; nodal segments and root segments) from in vitro plantlets; five auxins: indole-3-acetic acid (IAA), α-naphthaleneacetic acid (NAA), indole-...
