Four species of the genus Hedychium can be found in Brazil. coronarium is a endemic to India and In this paper, we collected six specimens H. for evaluation their volatile chemical profiles. For this, essential oils these were extracted using hydrodistillation from plant samples state Pará, Brazil, belonging Amazon region north country. Substance compounds identified with GC/MS.

An efficient protocol has been developed for regeneration of complete plants through somatic embryogenesis in H. coronarium. Creamish white, pale yellow and brown calli were obtained on MS medium supplemented with different concentrations of auxins [2, 4-Dichlorophenoxy acetic acid (2, 4-D), Indole-3 acetic acid (IAA) and 1-Naphthylacetic acid (NAA)] after 4 weeks. Creamy white calli developed ...

Five species of parasitic wasps associated with hesperiids from peninsular India are documented along with the description of a new species of gregarious endoparasitoid, Dolichogenidea cinnarae sp. nov. (Hymenoptera: Braconidae) parasitic on caterpillar of Borbo cinnara (Wallace) (Lepidoptera: Hesperiidae). Also, the gregarious larval parasitoid, Cotesia erionotae (Wilkinson) (Braconidae) and s...

OBJECTIVE For the past 2 decades there has been vigorous disagreement over the purported toxicity of Hedysarum alpinum seeds, and whether the consumption of such seeds was a factor in the 1992 death of Chris McCandless, the subject of the book Into the Wild. Our objective was to confirm or disprove the presence of L-canavanine (a nonprotein amino acid known to induce systemic lupuslike symptoms...
