in this study, a functional colorant, berberine, extracted from berberis vulgaris wood was applied onto wool fiber using the extract of roots of rumex hymenosepolus as biomordant. the effect of treatment variables on the color strength of dyed fibers was examined. the fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. dyed samples were tested for antiba...
Nutrient hot spots in the soil have a limited life span, but the costs and benefits for root foraging are still underexposed. We assessed short-term costs that may arise when a nutrient-rich patch induces root proliferation, but then rapidly disappears. Rumex palustris plants were grown with a homogeneous or a heterogeneous nutrient application. After root proliferation in a nutrient-rich patch...
Both red light (10 minutes) and 35 degrees C treatment (60 minutes) stimulate the germination of seeds of Rumex obtusifolius otherwise maintained in darkness at 25 degrees C. Fluence response curves were determined for the effect of red light to stimulate germination of seeds with and without 35 degrees C treatment. The endogenous far-red absorbing form (Pfr) level in the seeds was determined u...
