Effects of Short-Term Hypergravity Exposure are Reversible in Triticum aestivum L. Caryopses


Short-term hypergravity exposure is shown to retard seed germination, growth and photosynthesis in wheat caryopses. This study investigates the reversibility of effects of short-term hypergravity on imbibed wheat (Triticum aestivum var L.) caryopses. After hypergravity exposure (500 × g − 2500 × g for 10 min) on a centrifuge, exposed caryopses were kept under normal gravity (1 × g) up to six days and then sown on agar. Results of the present study showed that percentage germination and growth were completely restored for DAY 6 compared to DAY 0. Restoration of germination and growth was accompanied by increased α-amylase activity. The specific activity of antioxidative enzyme viz. catalase and guaiacol peroxidase was lowered on DAY 6 compared to DAY 0 suggesting an alleviation of oxidative cellular damage against hypergravity stress. Chlorophyll pigment recovery along with chlorophyll fluorescence (PI and Fv/Fm) on DAY 6 indicates a transient rather than permanent damage of the photosynthetic apparatus. Thus, our findings demonstrate that short-term hypergravity effects are reversible in wheat caryopses. The metabolic cause of restoration of seed germination and growth upon transferring the caryopses to normal gravity is performed by a reactivation of carbohydrate- metabolizing enzymes, α-amylase and alleviation of oxidative stress damage with subsequent recovery of chlorophyll biosynthesis and photosynthetic activity.
