Freezing Resistance in Tomato (Lycopersicum esculentum Mill.) Using Potential Cryoprotectors

Tomato (Lycopersicum esculentum Mill.) plants 'Manitú F1' were sprayed with several plant cryoprotection treatments at the phenological stage with plants bearing four true leaves. The active ingredients of the potential cryoprotectors used were: Me2SO, proline, polyvinylpyrrolidone (PVP),...

Description
Summary:Tomato (Lycopersicum esculentum Mill.) plants 'Manitú F1' were sprayed with several plant cryoprotection treatments at the phenological stage with plants bearing four true leaves. The active ingredients of the potential cryoprotectors used were: Me2SO, proline, polyvinylpyrrolidone (PVP), a preparation of free amino acids plus nitrogen and a preparation of glycerol plus vitamin E. The effectiveness of the cryoprotector was assessed 24 hours after spraying using differential scanning calorimetry (DSC) on leaf tissue and whole plant freezing simulations. The treatment composed of an aqueous solution of 5% glycerin and 0.35% vitamin E was found to be the most effective cryoprotector for reduction of freeze damage on tomato leaf tissue.
