Q.2 If one wants to find minerals and in the form they are mobilised in plant the how will an analysis of the exudate help?
The plant exudate (plant sap) is a mixture of the organic/inorganic compounds and ions, minerals, sugaes and amino acids. If we chemically analyse these we can get to know, which mineral nutrient is transported in which form in the plants. e.g., nitrogen is absorbed and transported a is NO and NO and sulphur in sulphate ion forms etc.
