Abstract
The authers intended to elucidate the growth phase of mint plant in a view of its nutritional physiology. The results obtained are discussed, in the present paper, under the following headings : - (1)Length and weight of plant at different stages of its growth. (2) Absorption of nutrients at different stages of growth. (3) Production of essential oil at different stages of growth. (4) Chemical composition of essential oil obtained at different stages of growth. (5) Physical properties of essential oil obtained at different stages of growth. (6) Percentage contents of menthol crystal, crystalizable by the freezing process, in essential oil at different stages of growth.
