The effect of accumulation of chilling hours and the rate of linear heat on the behavior of some pistachio vera varieties


Abstract in English

Winter chilling requirements are critical for flowering and fruiting of many fruit species, with evidence that pistachio has been adversely affected by warm winter, so that estimating chilling and heat requirements is crucial for identifying appropriate cultivars for given site. In our study, different levels of chilling hours were applied (500-600-700-800-900-1000-1100-1200-1300-1400 h).
