Abstract:

The present experiment was undertaken to study the effect of ethephon 39%SL on post-harvest quality of Tomato fruits (Solanum lycopersicon L.). The mature green tomato fruits were subjected to aqueous solution of ethephon 39%SL @ 1500, 2000, 2500, 3000 and 3500 ppm to record the data on colour development of fruit. Colour of fruits was observed to be improved with ethephon applications and maximized yellow colour development was noticed from 5^th day of ripening period. The weight loss higher with concentration of ethephon and ripening interval. Upto 7^th day of treatment fruit not showed any symptoms of rotting. But fruit firmness gradually reduced with advancement of storage in the treatments and at 3500ppm ethephon 39%SL treatment. The quality of fruit especially lycopene and TSS content increased with advancement of ripening period. Treatment with ethephon 39%SL @ 2500 ppm resulted in adequate ripening of fruits with uniform red colour, acceptable quality and better than all treatments of ethephon.
