| Abstract:
Glycinebetaine is thought to act in many organisms as a compatible osmotic solute and/or osmoprotectant in cells suffering from high or low temperature, water deficiency and/or high salinity. The response of processing tomato plants to foliar-applied glycinebetaine (Greenstim) purified from sugar beet was studied in timing and dose field trials over two years. The highest yield increases obtained with a single application of glycinebetaine were up to 30% in Australia and 50% in Spain. The yield increment was more evident in reduced irrigation conditions. Plants treated with glycinebetaine yielded more fruits than untreated plants. | |
