A number of inorganic elements are present in plants which also catalyse many enzymatic reactions. The existence of such inorganic elements in plants can be detected by the chemical tests of plant ash. Requirements for Detection of Ash: (a) Preparation of Ash Extract: For detection of various elements in plant ash viz., Ca, Mg, Fe, S, P, CI etc. ash [...]
In this article we will discuss about the tests for spectrophotometric determination of chlorophyll and carotenoids. Extraction of Chlorophyll and Carotenoids: Although chlorophyllous and carotenoid pigments may be extracted readily in organic solvents, for many algae, extraction is not complete unless the cells are ruptured. Therefore, filters should be placed with forceps into the base of a glass for drinking [...]
In this article we will discuss about the tests for quantitative estimation of cell sap chloride ion in plants. Among essential elements chloride is one of the important elements, which is required in trace quantity. But in saline habitat, where the soil have very high value of available chloride, it may pose detrimental effects on plants. However, there are certain [...]
