Ann. Entomol. Soc. Am. 81(3): 419-427 (1988) ABSTRACT The anthophorid bee, Hahropoda (=Emphoropsis [R. W. Brooks, personal communication]) laboriosa (F.), is a locally abundant, vernal, univoltine species. It flies from February through April in Georgia and Alabama. In these states, females are oligolectic on Vaccinium spp., particularly V. ashei Reade and V. corymbosum L., with Gelsemium sempe...

In this study, the contents of myricetrin, quercitrin and afzelin in Cercis chinensis leaves were determined simultaneously by 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM] BF4/70% ethanol microextraction combined with High Performance Liquid Chromatograph (HPLC) analysis. The mobile phase was eluted with an Agilent ZORBAX SB-C18 column (4.6 mm×5 mm, 5 μm), B was methanol and C was 0.1% ...

Plants that form root-nodule symbioses are within a monophyletic 'nitrogen-fixing' clade and associated signalling processes are shared with the arbuscular mycorrhizal symbiosis. Central to symbiotic signalling are nuclear-associated oscillations in calcium ions (Ca(2+) ), occurring in the root hairs of several legume species in response to the rhizobial Nod factor signal. In this study we expa...

Eastern redbud, Cercis canadensis L., is a popular ornamental tree in the U.S. and has flower colors of purple-type, red-type, white-type. Most redbuds cultivars have purple-type flowers. Red-types white-types are much less common. These unusual become an important trait for incorporation into novel redbud cultivars. seedlings require 3–5 years before blooming, making color selection slow expen...
