Competition and herbivory are ubiquitous environmental challenges that affect most plants. We examined the influence of phenotypic responses to either competition or herbivory on the subsequent response of the plants to the other factor. The stem-elongation response of Chenopodium album to light competition attenuated its resistance to caterpillar herbivory in terms of herbivore mortality, but ...

The present paper deals with the study of biomass production of manures in the greens such as Amaranthus polygamus and Amaranthus viridis of the family Amaranthaceae and Spinacea oleracea of the family Chenopodiaceae. The medicinal uses and pharmaco - phytochemical analysis were also carried out for the plant species which are widely used as greens.

Periplaneta americana (Blattodea:Blattidae) toxicity of 17 different plant-based essential oil against, adults were investigated. Used oils Lavendula angustifola (Lamiaceae), Zingiber officinale (Zingiberaceae), Citrus bergamia (Rutaceae), Juniperus virginiana (Cupressaceae), Piper nigrum (Piperaceae), Curcuna longa Betula lenta (Betulaceae), Myristica fragranaceae (Myristica fragranaceae), com...

Accurate three-dimensional imaging of plant structures and gene activity will facilitate a deeper understanding of the mechanisms that underlie plant growth and development. Lee et al. (pages 2145–2156) used optical projection tomography (OPT) to capture three-dimensional data from plant specimens. OPT has the advantages of other optical methods but with greater penetration and the ability to g...

The effects of root diffusates of selected plants within the families Chenopodiaceae and Cruciferae and the hatching agent zinc chloride were tested for their effects on hatching and emergence of juveniles from cysts of Heterodera schachtii and a race of H. trifolii parasitic on Chenopodaceae and Cruciferae in The Netherlands. Although all diffusates strongly stimulated hatching of juveniles of...
