Methyl Salicylate Secretory Cells in Roots of Viola arvensis and V. rafinesquii (Violaceae)
The aromatic roots of Viola arvensis and V. rafinesquii were studied in order to determine the chemical nature and anatomical localization of their volatile compounds. Gas chromatography and mass spectroscopy revealed a single detectable volatile compound, methyl salicylate. Light microscopy and differential staining with Sudan III indicates the source of this compound to be enlarged secretory ...
متن کاملProtective effect of Viola tricolor and Viola odorata extracts on serum/glucose deprivation-induced neurotoxicity: role of reactive oxygen species
Objective: Oxidative stress plays a key role in the pathophysiology of brain ischemia and neurodegenerative disorders.Previous studies indicated that Viola tricolor and Viola odorataare rich sources of antioxidants. This study aimed to determine whether these plants protect neurons against serum/glucose deprivation (SGD)-induced cell death in an in vitro model of ischemia and neurodegeneration....

متن کاملBrushing pansy (Viola tricolor L.) transplants: a flexible, effective method for controlling plant size
Though brushing is an effective method for controlling excessive elongation in many species, its adoption by the commercial plug transplant industry will depend on the ease and flexibility of its application. Brushing was applied to pansy (Viola tricolor L.) seedlings growing at a density of 1500 plants m-2 by daily stroking with 20/20 gauge netting. In dose response experiments, final petiole ...
متن کاملPotential selection for female choice in Viola tricolor
That sexual selection can be an active force in plant evolution is still under debate. When the number of pollen grains deposited onto a stigma exceeds the number of available ovules, competition among pollen grains for fertilizations will result in selection on traits that increase siring ability (e.g. pollen tube growth rate). The pistil can be regarded as an arena for pollen competition, whe...
