Abstract:
Biopolymer produced from natural resources used in various industrial ranging from food, pharmaceutical and medicines etc. are in increasing demand globally. Therefore the investigation on “Comparative study of biopolymers exudation and tapping techniques of major Gum/Resin trees of Balrampur, (North Chhattisgarh Region)” was carried out at village Chando district Balrampur (Chhattisgarh) and the laboratory work was done in the department of Plant Physiology, Agricultural Biochemistry and Medicinal and Aromatic plants, Collage of Agriculture, IGKV, Raipur (C.G.) during the year 2018-19 and 2019-20 to compare various methods of tapping of biopolymers and evaluate the qualitative and quantitative traits of gum in two experimental trees i.e., Dhawara (Anogeissus latifolia) and Salai (Boswellia serrata Roxb.) in a different season of tapping to develop the techniques for sustainable production and quality. The analysis was done using RBD replicated thrice. The four mechanical T₁ Single cut (Traditional), T₂ (Semi arc), T₃ (single V shape), and T₄ (double V shape) and in use of 12 gum enhancer i.e. T₁ Control (@4 ml distilled water), T₂ (@3.9% Ethephon), T₃ @(4.8% Ethephon), T₄ (@5.5% Ethephon), T₅ (@10% H₂SO₄), T₆, (3.9% Ethephon + 10% H₂SO₄), T₇ (@4.8% Ethephon +@ 10% H₂SO₄), T₈ (@5.5% Ethephon + @10% H₂SO₄), T₉ (NAA @250 ppm), T₁₀ (Maleic Hydrazide@5%), T₁₁(L- methionine @250 ppm), T₁₂ (Jasmonic Acid JA @1%). The main aim of the study was to develop the technology for tapping the tree throughout the year. As compared to mechanical method as well as traditional methods the use of gum enhancer was found to be significantly superior and safe. In Dhawda (Anogeissus latifolia) the use of Ethephon and H₂SO₄ (@10%) was found to be effective in summer while in winter tapping its combined effect (ethephone + H₂SO₄ @10%) was found to be best. However, in Salai (Boswellia serrata Roxb.) combined effect of ethephone + H₂SO₄ @10% was found to significantly effective in creating artificial stress to induce the mechanism of gummosis in three experimental trees. The physiochemical properties of gum tapped by mechanical, traditional and gum enhancer indicated that there were non-significant differences in their properties of gum in moisture content, ash content, protein and nitrogen content, viscosity, solubility, and pH value.
