Effect of Drought Stress on Epicuticular Wax Load in Peanut Genotypes [PDF]

open access: yes, 2015
The changes in epicuticular wax load (EWL) and the leaf temperature in two peanut genotypes such as JL-24 (drought susceptible) and K-9 (drought tolerant) was studied under drought stress and its recovery. The drought stress was induced at different soil

Drought Stress and the Need for Drought Stress Sensing in a World of Global Climate Change

open access: yes, 2012
Water scarcity imposes huge reductions in crop yield and is one of the greatest limitations to crop expansion outside present-day agricultural areas. Because the scenarios for global environmental change suggest a future increase in aridity and in the frequency of extreme events in many areas of the earth (Schar, 2006), maintaining crop yields under ...
