Abstract

sweet violet (viola odorata L) as a valuable medicinal plant growing in the north of Iran, and valuable secondary metabolites substance include violin alkaloids, essential oils include ivanine, saponin, glycoside, methyl salicylate, mucilage, cyclotites, vitamin A, vitamin C and alkaloids. The purpose of this study was to investigate the ecological factors effect on some morphological characteristics and photosynthetic pigment of the plant. Therefore, samples were collected from three regions of Mazandaran province with different high altitude. The results showed that although photosynthetic pigments were changed by height, but were not statistically significant. Also, the amount of carotenoid decreased with increasing height. Leaf length traits were significant at 5% level and the two high altitudes were in the same group and significantly increased than low altitude in Neka region. Therefore, it can be concluded that in sweet violet morphological traits are more affected by ecological factors than photosynthetic pigments.
