Interrelationship between Geochemical Characters and Metabolites of Urban Tree Species in Industrial Estate, Central Gujarat, India
Description
The aim of the present study was to assess geochemical characters and metabolites of urban tree species in industrial estate of Anand District, Gujarat, India, for four months (January 2014 to April 2014) at three major crossroads viz. GIDC Crossing (GC), Pavan Crossing (PC) and Karamsad Crossing (KC). Soil quality was determined using parameters such as Temperature, pH, Phenolphthalein Alkalinity (PA), Total Alkalinity (TA), Carbonates, Bicarbonates, Total Hardness (TH), Calcium (Ca), Magnesium (Mg), Chloride (Cl), Sulfate, Phosphate, Nitrate, Total Organic Carbon (TOC), Total Organic Matter (TOM), Chromium (Cr) and Iron (Fe). Metabolites such as Carbohydrates (CB), Proteins (PR), Amino Acids (AA) and Phenols (Ph) of urban tree species [Azadirachta indica (AI), Peltoforum pterocarpum (PT), Polyalthia longifolium (PL)] was estimated. At GC, soil around AI contained highest contents of Ca, Cl, TOC, TOM & Cr; PT contained more Bicarbonates, TH, Mg & Fe, and PL with high amounts of pH, TA, Sulfate, Phosphate & Nitrate. At PC, soil of AI contained highest contents of TA, Bicarbonates, Ca & Phosphate; PT with more pH, TH, Mg, Sulfate, Nitrate, TOC, TOM, Cr & Fe, and PL contained high Cl. At KC, soil of AI enriched with pH, Sulfate & Nitrate; Ca, Cl, TOC, TOM & Cr; PT with TA, TH, Ca, Cl & Fe, and PL was rich in TA, Bicarbonates, Phosphate, TOC, TOM & Cr. Overall, soil of GC contained more contents of TH, Ca, Mg, Phosphate, Nitrate, TOC, TOM & Cr; PC was rich in TA, Bicarbonates, Cl, Sulfate & Fe, and KC contained high pH. In case of AI, Carbohydrates were more in KC, Proteins & AA in PC, and Phenols in GC. In case of PT, Carbohydrates were high in KC, Proteins & Phenols in PC. In case of PL, Carbohydrates, AA & Phenols were more in GC, and Proteins in PC. Overall, Carbohydrates & Proteins were high in PL, and AA & Phenols in AI. All urban trees were rich in mean protein contents. In case of soil, strong positive correlation was observed between pH & TOM, TA & Bicarbonates, Bicarbonates & Ca, TH with Ca & Mg, Ca & Mg with Phosphate, Sulfate & Fe with Cl, Sulfate & Fe, Phosphate & Nitrate, Nitrate & Cr, TOC & TOM, and TOM & Cr. Similarly, strong positive correlation was observed between metabolites (Carbohydrates & Proteins, and Proteins & Phenols). Correlation Coefficient Matrix (r) of soil parameters and metabolites revealed strong positive correlation between Carbohydrates and Phosphate, Proteins & Phenols with Nitrate, and AA & Bicarbonates.
