“…Such an ability of plants to show phenotypic changes in different environments, especially under differential abiotic conditions, is termed as phenotypic plasticity (Majetic, Raguso, & Ashman, 2009). Till now, existence of geographic variation or phenotypic plasticity in terms of volatiles has been shown mainly in the floral scents (Dotterl, Wolfe, & Jurgens, 2005;Knudsen, 2002;Svensson et al, 2005) and in the essential oils in the vegetative tissue (Adams, 2001;Neffati et al, 2009). However, in most of these cases, plants belonged to the natural populations and hence they can show some genetic variation, which along with the varied environmental conditions could account for the observed variation in the volatile composition (Majetic et al, 2009).…”
