Investigation of pistachio trees of Kerman pistachio shell cultivar

Pistachio trees of Kerman cultivar were high and low in natural cycles. The two hypotheses tested were:

The amount of sugar at the beginning of the season in the tested organs of trees with high yield (high load) is higher than trees with low yield (low load). This hypothesis was confirmed by measuring the amount of sugar and starch in leaves, inflorescence buds, cluster axis, pistachios and main branches, secondary and roots of high-yielding trees compared to low-yielding trees.

The amount of sugar in the tissues of fertile trees remains high in the first wave of pistachio shedding that occurs at the beginning of the growing season. This hypothesis was also confirmed.

In fact, soluble sugars and starches in high-yielding trees remained high for up to two months after all flowering. Inflorescence on low-loading trees The amount of soluble sugars and starch was 13 times higher than inflorescence buds on high-loaded trees. At this time, the inflorescence buds of low-yielding trees were 50% more dry than the inflorescence buds of high-yielding trees.
