ABSTRACT
Two populations of Trifolium alexandrinum were studied from a normal and a disturbed site for phenotypic differentiation. Morphological variation was assessed from twenty individual plants from each of two field provenances. Similarly, phenotypic and genetic components of variability were revealed after their transplantation to common garden conditions. Consistent measurements for various biometric and biosynthetic attributes revealed that both populations were morphologically differentiated but alteration of certain character expressions was more profound for the disturbed provenance. Likewise, common garden cultivation revealed that much of this variation has environmental component rather than genetic variability. Therefore, environmental fluctuations appear to generate flexibility of morphological responses. It is much likely that response flexibility has allowed the species to withstand spatial and temporal disturbances and seems to be an underlying phenomenon of adaptation to environmental constraints.
