Cracking of pomegranate fruit is a general problem throughout its growing areas and among all
varieties, however, the magnitude of the problem is more in arid region. Relative water content and water
potential of leaf as indicative of water stress directly affect the magnitude of cracking in pomegranate
fruits. Also, both these physiological parameters are likely to be influenced by high temperature stress as
measured by canopy air temperature difference (CATD) and fruit air temperature difference (FATD). Percent
fruit cracking in different pomegranate varieties ranged from 18.3% in P23 to 62.6% in Jodhpur Red.
However, irrespective of cultivars on an average 36% fruit get cracked under prevailing conditions of
experimental site. Canopy temperature was lower than air temperature, whereas, fruit surface temperature
was higher than air temperature. Both CATD and FATD were significantly correlated with leaf water potential
and relative water content. The cultivar having higher leaf water potential and RWC reflected lowest fruit
cracking and vice-versa. Stepwise regression analysis indicated that temperature mediated leaf water
potential had direct impact on incidence of fruit cracking in pomegranate as with increasing leaf water
potential; cracking percent reduces across the varieties studied in present investigation. Such relationships
may help in future to identify suitable cultivars for a specific region as well to adopt suitable preventive
measures to reduce fruit cracking in pomegranate
