Generally, Abutilon species contain considerable amounts of mucilage due to which they are used for the treatment of rheumatism and as demulcent and diuretic agents [1 – 3].

Variations in climate are widely recognized as central factors governing the competitive balance in mixedspecies plant communities. In agricultural systems, highly variable patterns of crop yield reduction as a function of weed density have been documented across sites and among years at the same site for several crop–weed combinations. This variation is typically attributed to contrasting envi...
Plastic stem-elongation responses to the ratio of red:far-red (R:FR) wavelengths enable plants to match their phenotype to local competitive conditions. However, elongation responses early in the life history may occur at the cost of reduced plasticity later in the life history, because elongation influences both allocation patterns and structural integrity. A common-garden experiment was perfo...
