We show that augmenting an English auction with a buy price can improve the seller’s profits ...

Plant catalases exhibit spatial and temporal distribution of their activity. Moreover, except from the typical monofunctional catalase, a bifunctional catalase-peroxidase has been reported. The aim of this study was to investigate whether the leaf and root catalases from six different plant species (Lactuca sativa, Cichorium endivia, Apium graveolens, Petroselinum crispum, Lycopersicon esculent...

Plants are an important source of natural active products that are different, based on mechanism and biological properties. Celery ( Apium graveolens L) is a plant from the apiaceae family and phenolic and antioxidant compounds of this plant have been studied by several scientists.

Enantioselective hydrolysis of bromo- and methoxy-substituted 1-phenylethanol acetates was conducted using comminuted carrot (Daucus carota L.) and celeriac (Apium graveolens L. var. rapaceum) roots. Hydrolysis of the acetates led to alcohols, preferentially to R-(+)-enantiomers. Efficiencies of both reactions - hydrolysis of the acetates with an electron-donating methoxy group and oxidation of...

Three Apium graveolens (L.) varieties and cultivars within varieties were evaluated for host plant suitability to two polyphagous lepidopteran herbivores: the beet armyworm, Spodoptera exigua (Hiibner), and the cabbage looper, Trichoplusia ni (Hiibner). Overall, there were no significant differences in survivorship, developmental time, and pupal weight of S. exigua or T. ni reared on the two va...
