L. is an important cash crop commercially planted for its diverse utilities. Coconut water (liquid endosperm) is widely used as a revitalizing health drink and is a cheaper source of many bioactive compounds especially plant growth regulators (PGRs). However, the dynamics of PGRs during liquid endosperm formation and the varietal difference have not been studied well. In the present investigation, two cultivars; tall (West coast tall) and dwarf (Gangabondam) and their reciprocal hybrids (T×D and D×T) were screened for the study of dynamics of PGRs during liquid endosperm formation. Fifteen hormones belonging to seven major classes of phytohormones, viz., IAA, IBA, SA, GA
