Pigments percentage (chlorophyll and carotenoids) were increased by all treatments, these results were correlated with the vase life results, however, high concentration of pigments in treated leaves could be due to the effect of anti-transpirant, in improving water use efficiency, by reducing leaf transpiration rate via increasing leaf reflecting or inducing stomata closure. These results are in agreement with those obtained by Rabiza-Świder and Skutnik (2004) who found that, postharvest longevity of Zantedeschia and Hosta was extended by inhibiting leaf senescence through delaying chlorophyll loss and soluble protein degradation. Nevertheless, Abd El-Kader et al. (2007) recorded that spraying antitranspirants increased growth parameters. El-Abd (1996) on citrus, Ranney et al. (1989) on cherry trees recorded that pruning and antitranspirant were successful in delaying plant water stress, and relative growth rate.
