Plant morphology deals with knowledge of physical form and external structure of plants (Raven et al., Biology of plants 7th ed., 2005) which includes plant development and formation. Plant morphology is always comparative approach to examine structural and developmental characteristics of same or different floral species and by virtue of different internal and external factors on them. The Structural and developmental aspects in plant morphology are not confined to only vegetative (somatic) parameters but also include, the reproductive parameters. The vegetative parameters deals with characteristics of stem, root and leaves where as reproductive parameters deal with characteristics of flower, fruit and seed. Morphological characteristics related to growth factors have greater attraction for studying the impact of physical factors like light, gravity etc., Growth in the plants is not only account of cell division but also due to cell elongation. Both the things are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al., 1983) Usually these PGRs produced endogenously and show their deep impact on plant morphology. Certain exogenous chemical compounds also show significant impact on plant morphology by direct interaction or modulating plant physiology.
