Abstract
As in other temperate species, the pomegranate tree shows different ph enological characteristics through its vegetative cycle in response to changing temperature. This phenology has been studied as a basis for comparisons of the successive stages of growth and reproduction in dif ferent geographical areas and conditions. The variety Mollar de Elche was studied, since it is grown on more than 95% of the total area devo ted to this crop in Spain. Thirteen phenological-stages were identifie d during the annual cycle, starting at bud in dormancy and finishing a year later with leaf fall. These stages are denoted using the BBCH Ge neral Scale which uses numerical codes to represent particular stages. The code uses a two-digit number to describe the different phenologic al states and makes it possible to distinguish between principal and s econdary stages of development. The duration of stages was measured in days and as accumulated degree-day.
