Bidens bipinnata L. (Asteraceae): A new species record to Rajasthan state, India

Bidens bipinnata L. (Asteraceae), first-time distribution records from the State of Rajasthan. Previously, this species was distributed only in Jammu & Kashmir, Himachal Pradesh, Uttar Pradesh and Punjab. In Rajasthan, it is reported as an addition to the flora of the State. This article provides habitat, distribution, detailed description, plant association, flowering and fruiting time, […]

Cladistics of Western Himalayan Artemisia L. (Anthemideae, Asteraceae) reconstructed on morphological traits

The large size and confounding morphological characters of genus Artemisia has created problems of generic delimitations and infrageneric classification for taxonomists. This work suggests the use of additional morphological traits in identification and classification of Artemisia. It is observed that same species show polymorphic characters under certain environmental conditions that make them more difficult to […]

Variation of Palynomorphological and pollen production of some invasive plant species of Asteraceae family in conservation areas of tropical rain forest, West Sumatra, Indonesia

Some conservation areas in tropical forests of West Sumatra have been invaded by some invasive plants species from family Asteraceae. Characterization and pollen production of these plants are very useful to identify and clarify their invasiveness. This paper analyzed the ability of twelve invasive plants in producing the pollens, as determinant agents of reproductive biology. […]

In vitro organogenesis of Ageratum houstonianum (Asteraceae)

Regeneration of whole plants from tissue explants is a key technology for crop improvement and plant biotechnology and has critically contributed to the green revolution. In this study, the effects of MS medium supplemented with various concentrations of Kin and IAA combination on induction of callus, shoot and root induction and multiplication, and plantlet formation […]

Chemical composition and insecticidal activity of essential oil of Artemisia herba alba (Asteraceae) against Ephestia kuehniella (Lepidoptera: Pyralidae)

Plant secondary metabolites play an important role in plant-insect interactions and therefore such compounds may have insecticidal or biological activity against insects. In the present study, aerial parts of Artemisia herba alba Asso were subjected to hydro distillation using a Clevenger-type apparatus and the chemical composition of the volatile oils was studied by GC-MS. Forty […]
