Elastic Stability Analysis of Euler Columns Using Analytical Approximate Techniques

Abstract

High temperature and drought are the most concurrent climate factors. An experiment was conducted with two\rgenotypes of chickpea (Cicer arietinum L.) in open top chambers to study the interactive effect of drought, elevated CO2\rand high temperature on oxidative stress and ROS scavenging enzyme. High temperature exacerbated drought effects,\rwhereas elevated CO2 ameliorate stress impact in chickpea. Oxidative stress parameters (lipid peroxidation, H2O2 levels)\rwere higher in Flip 90-166 as compares to drought tolerant genotype ICC 4958. Increase in oxidative stress will increase\rthe antioxidants enzymes (SOD, APX and CAT) under drought and high temperature alone as well as in combination.\rOverall, elevated CO2 reduced drought and high temperature effects in chickpea and this amelioration was stronger in\rFlip 90-166. This is explained by stronger reduction in H2O2 generation under elevated CO2 and a higher availability of\rmolecular antioxidants.
