Kurup, V.V.G.K.Voleti, S.R.Rajagopal, V.2014-06-252014-06-252007-02Indian J.Plant Physiol. 1993 v-36 i-2 p-103-106http://hdl.handle.net/123456789/3266The seasonal variations in stress parameters like leaf water potential and electrolyte leakage were studied in the popular coconut cultivar namely West Coast Tall (WCT) and the two hybrids WCT x Chowghat Orange Dwarf (COD) and COD X WCT, in relation to weather variables and soil moisture content. There was a significant difference in physiological parameters among the genotypes only during the stress period, characterized by high evaporative demand. The hybrid COD x WCT was found to be most sensitive to moisture stress as indicated by low leaf water potential, and high electrolyte leakage. This implies that the tall genotype and the hybrid with tall female parent (WCT X COD) are relatively more tolerant to moisture stress than the hybrid with dwarf female parent (COD X WCT).enArticle
