Abstract Alternate bearing in the pistachio ( Pistacia vera L.) is brought about by abscission of inflorescence buds during July and August when seed growth and development take place. There was rapid accumulation of sugars and conversion to fat in the nuts at that time, but sugar and starch levels in the bark and wood of nut-bearing branches were not appreciably different from those in similar tissues of non-bearing branches. The inflorescence bud-drop phenomenon does not appear the result of carbohydrate deficiency.
