Abstract:

The present investigation was carried out at Horticultural Research Centre, Patharchatta, GBPUA&T, Pantnagar during September, 2015 to June, 2016. The experiment was conducted to study the effect of ethrel, potassic chemicals i.e. di-potassium hydrogen-ortho-phosphate (K2HPO4), potassium di-hydrogen orthophosphate (KH2PO4), potassium nitrate (KNO3) and thiourea on quality attributes of litchi cv. Rose Scented. The treatments included T1-ethrel (400 ppm), T2-KNO3 (1%), T3-K2HPO4 (1%), T4-KH2PO4 (1%), T5-thiourea (1%), T6-K2HPO4 (2%), T7-KH2PO4 (2%), T8-K2HPO4 (1%) + KNO3 (1%), T9-KH2PO4 (1%) + KNO3 (1%), T10-K2HPO4 (1%) + thiourea (0.5%), T11-KH2PO4 (1%) + thiourea (0.5%), T12-KNO3 (1%) + thiourea (0.5%) and T13 as control (water spray). The experiment was laid out in randomized block design with 13 treatments and 3 replications. Three spray of each treatment was applied during last week of September to November (at 20 days interval). The results indicated that all the treatments significantly improved quality parameters of litchi fruits as compared to control. Maximum TSS (19.22o Brix), TSS/acidity ratio (61.44), reducing sugar (11.87%) total sugar (13.34%) and minimum acidity (0.31%) were reported with the application of ethrel @ 400 ppm whereas maximum ascorbic acid (33.17 mg/100 g pulp) was observed in T8 (K2HPO4 @ 1% + KNO3 @ 1%) treatment.
