Abstract
Pistachio is an economical horticultural crop in Iran.
To enhance the pistachio nut quality, knowing the effective physiological mechanism is so important, therefore in order to investigate inflorescence bud type on fruit set and some quantitative and qualitative factors in two commercial pistachio cultivars (Ouhadi and Ahmadaghaiee) were measured in 2008 at Iran’s Pistachio Research Institute (IPRI) orchard as a Split plot design with three levels of bud size and tree replications.
In selected trees some shoots were selected and marked for their flower buds.
The bud type and dimension were measured and divided into large/medium/small bud size.
Primary fruit set was measured as number of fruits per cluster.
Second measuring of fruit set was done after June.
Each cluster of fruits was harvested separately and transferred to the lab for measuring some qualitative and quantitative factors.
According to the analysis of variance, there was a significant difference (P<1%) between effect of different treatments on primary fruit set and fruit set after June.
Large and medium buds had the most amount of fruits.
There was a significant difference (P<1%) between the effect of bud type on total number of fresh and dry pistachios.
Small buds had least total number of fresh and dry pistachios.
There was a significant difference (P<1%) between total pistachio dry and fresh weight.
Also, there was a significant difference between the effect of bud type on number of fresh and dry splitting pistachio, and large and medium size bud had most splitting percent when compared to small.
In conclusion we found as bud dimension increases, the fruit quality and fruit set will increase.
