Catecholase and cresolase (PP0) enzyme activity and phrnolic conyent were measured in 24 mango varieties in newly emerged vegetative growth during the September-October flush in 1997 and 1998. Incidence of malformation was recorded in March-Aoril 1998 and 1999. Enzyme activity and phenolic content varied widely among varieties, and was highest in 'Bhadauran' and lowest in 'Tommy Atkins'. Floral malformation incidencewas highest (53.75%) in 'Tommy Atkins'and lowest in 'Bhadauran'(1.10%). A strong positive correlation was found between the incidence of floral malformation and both enzyme activity and phenolic content. Thus PPO activity can be used as a biochemical index for screening mango germplasm against malformation. |
