The genus Amaranthus contains 44 species and belongs to the family of Amaranthaceae classified within the order of Caryophyllales. Within this order a number of allergenic species including Amaranthus retroflexus (Redroot pigweed), Beta vulgaris (sugar beet), Chenopodium album (Lambsquaters), Kochia scoparia (Burning bush), and Salsola kali (Russian thistle) have been acknowledged by the WHO/IU...

A non-sodic, non-saline sandy loam soil was salinized to anion-cation ratios similar to those naturally occurring in Iraq and California. The interactions of saline soils (conductivities 4, 8, 12 and 16 mmhos/cm) with a moderately salt-tolerant plant (Lycopersicon esculentum 'Marimond') and a plant parasitic nematode (Meloidogyne javanica) were investigated. Plant parasitic nematodes were shown...

Germacrene C was found by GC-MS and NMR analysis to be the most abundant sesquiterpene in the leaf oil of Lycopersicon esculentum cv. VFNT Cherry, with lesser amounts of germacrene A, guaia-6,9-diene, germacrene B, b-caryophyllene, a-humulene, and germacrene D. Soluble enzyme preparations from leaves catalyzed the divalent metal ion-dependent cyclization of [1-3H]farnesyl diphosphate to these s...

The eVect of Wve diVerent food resources (Coccus hesperidum honeydew, honey-water, Lobularia maritima, Fagopyrum esculentum and water only) on the longevity, fecundity, and progeny Wtness of female Gonatocerus ashmeadi, an egg parasitoid of the glassy-winged sharpshooter (Homalodisca vitripennis) was investigated in the laboratory. Female G. ashmeadi survived 208–405% longer (up to 11.7 days lo...
