dc.description.abstractCoconut palms of three tall varieties (West Coast Tall (WCT), Philippines Ordinary (PO) and Andaman Ordinary (AO), two dwarf varieties (Malayan Yellow Dwarf (MYD) and Gangabondam (GB)) and three hybrids (WCT x Chowghat Orange Dwarf (COD), COD xWCTand WCT x WCT) were assayed for the activities of stress sensitive enzymes viz., acid phosphatase (APH), L-aspartate : 2 Oxoglutarate amino transferase (AOAT), Superoxide dismutase (SOD), Peroxidase (POD) and Polyphenol Oxidase (PPO) during the two distinct stages viz., non-stress (September / October) and Stress (February / March) of 1989 and 1990. In general, there was stress-induced increase or decrease in the activity of enzymes among the cultivars/hybrids, based on which they were ranked. The cultivar/hybrid with higher activities of SOD and POD and lower activities of PPO, APH and AOAT could be designated as drought tolerant. Accordingly, the order of tolerance was found to be WCT x WCT > WCT > PO = WCT x COfr > AO > GB = COD x WCT > MYD.en_US
