Abstract:

To study the effect of pre-harvest spray of plant elicitors at flowering on fruit characters and post-harvest behaviour of papaya, was planned at Horticultural Research station, Anantharajupeta, Railway Kodur, Andhra Pradesh during 2015-16 and 2016-17 with the application of salicylic acid (50 ppm, 100 ppm, 150 ppm), jasmonic acid (50 µM, 100 µM, 150 µM) once at 50 Days After Anthesis and twice at 50 Days After Anthesis and 75 Days After Anthesis and control (no spray). The data revealed that T9 (SA @ 150 ppm at 50 and 75 DAA) recorded highest fruit weight (1.03 kg), fruit length (17.89 cm), fruit girth (41.34 cm), fruit volume (1.38 liters), cavity length (12.64 cm), cavity width (7.37 cm), weight of the pulp (0.87 kg) and flesh thickness (2.95 cm). T8 (SA @ 100 ppm at 50 and 75 DAA) and T7 (SA @ 50 ppm at 50 and 75 DAA) were observed to be on par with T9 in majority of the cases with respect to these fruit physical characters. The corresponding lowest values in this regard were recorded with T13 (control). The positive influence of T9 and T8 was also observed on increased shelf life of papaya fruits (10.5 and 10.17 days respectively). However, the fruits obtained from untreated plants (T13) recorded minimum shelf life (6.17 days). The quality attribute such as T.S.S. showed an increasing trend up to 9 days after storage and decreased further.
