Before

The surfaces of plant organs are often covered by various non-glandular and glandular trichomes. Scientific interest in trichomes is established on their functional and toxonomic importance and on the economic usefulness of some trichome- produced substances. Trichomes are epidermal appendages of various form, structure and function. They are derived from various kinds of epidermal outgrowths on vegetative organs like stem or leaf. Trichomes are considered as a mechanical barrier against external factors, such as animals and pathogens. They also serve to restrict loss of water or to give protection against extreme temperature and ultraviolet radiation (Werker, 2000). The characteristics of trichomes and the composition of secretory substances secreted by them, vary greatly among species and are used in plant classification to distinguish between the related genera or species (Spring, 2000).
