Condition of leaves and flowering in high and low load conditions

The leaves of pistachio trees store sugar pistachio shell and starch in fertile conditions for 60 days after the full flowering stage, while the trees store only soluble sugars in low-load conditions. 60% of pistachios fall by 30 days after the full flowering stage and 25% of the fall occurs in the next 30 days at the same time as the accumulation of sugars in the leaves of fruit trees. Fruiting and falling flowers are accompanied by competition for nutrients from growing fruits with vegetative and reproductive organs. In the first sampling date 10 to 60 days after the stage of full flowering in circumcision in fertile conditions more soluble sugar compared to trees in low load conditions in leaves and flower buds of wood this year. There were. In the early stages of fruit growth, the growth rate of leaves in high-yielding trees was higher than low-yielding trees. Because pistachio fruit growth occurs 76 days after flowering, most of the dry weight loss in the inflorescence buds of the leaves and the wood of the current year also occurs during this time of the annual wood of the cluster axis. Carbohydrate storage prepares for the initial growth of fertile trees, but between 10 and 60 days after full flowering, 85% of the fruits and 40% of the flower buds fall off.
