ABSTRACT
A field experiment was conducted for three years (2009, 2010 and 2011) to investigate the effects of various PGRs on the development of pink berries in the skin of Thompson Seedless during maturation at Manjri Farm (Pune) India. The pooled results indicated that amongst the various PGRs, the treatment of 2-CEPA and ABA to grape resulted in significantly highest pink berries. As opposed, NAA, CPPU and 4-CPA treated berries resulted in significantly lowest pink berries in the skin of Thompson Seedless grapes. Obviously the percent pink berries and the total phenols in the berries recorded the similar trend as that of the anthocyanins in Thompson Seedless. The results suggested the use of PGRs in controlling pink berries in Thompson Seedless grapes in-vivo during maturation.
