The fumigant toxicity of various essential oils and selected monoterpenoid components were tested against the adult German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae). Responses varied according to plant material, concentration, and exposure time. High insecticidal activity against adult B. germanica specimens was achieved with allyl isothiocyanate (component of horseradish)...

Since L. Guignari's investigation (1884) various investigators have reported the studies on plants in the genus Allium of Liliaceae, as some species in this genus are cultivated and are noteworthy from the cytological point of view. According to T. Suto's papers (1936, 1936) on the phylogenetic discussion of Liliaceae and Amaryllidaceae, which show the fact that the idiogram type of the chromos...

Monocots are one of the most diverse, successful and economically important clades of angiosperms. We attempt to analyse the complete plastid genome sequences of two lilies and their lengths were 152,793bp in Lilium longiflorum (Liliaceae) and 155,510bp in Alstroemeria aurea (Alstroemeriaceae). Phylogenetic analyses were performed for 28 taxa including major lineages of monocots using the seque...

BACKGROUND AND AIMS Variation in the relative female and male reproductive success of flowering plants is widespread, despite the fundamental hermaphroditic condition of the majority of species. In many hermaphroditic populations, environmental conditions and their influence on development and size can influence the gender expression of individuals through the formation of hermaphroditic and un...
