Monitoring cell energy, physiological functions and grain yield in field-grown mung bean exposed to exogenously applied polyamines under drought stress

Abstract: Polyamines are new plant growth regulators and intracellular messengers that regulate plant growth, development, and responses to abiotic environmental stresses. However, little is known about the impact of different polyamines on physiological and biochemical processes of field-grown plan...

Average of two years results showed that compared with control, water stress significantly (P < 0.05) reduced adenosine three phosphate (ATP), chlorophyll content index (CCI) and chlorophyll stability index (CSI), rubisco activity, efficiency of photosystem II (Fv/Fm), endogenous polyamine contents, membrane stability index (MSI), nitrogen (N2), potassium (K+), calcium (Ca2+), magnesium (Mg2+), and grain yield, while polyamine oxidase activity, antioxidant enzymes activity, reactive oxygen species (ROS) and lipid peroxidation (MDA) increased significantly (P < 0.05) upon exposure to water deficit stress.
