SELECTION OF ROOTSTOCKS WITHIN THE PRESENT STANDARD PISTACHIOS
SELECTION OF ROOTSTOCKS WITHIN THE PRESENT STANDARD PISTACHIOS
(1987 – 1991)
Azmi ULUSARAC1
Objective
The goal of this research was to select the most effective Pistachio rootstock types showed the best crown growth and productivity in the present conditions.
Materials and Methods
The number of observations were increasedconsidering data about varieties at this period. Measurements including the third period were given in the below;
1-) Data of circumference of below the budded area of rootstocks (cm/tree)
2-) Data of circumference of the budded area of rootstocks (cm/tree)
1-) Data of circumference of above the budded area of rootstocks (cm/tree)
1-) Data of circumference of below the budded area of varieties (cm/tree)
1-) Data of circumference of below the budded area of varieties (cm/tree)
1-) Data of circumference of below the budded area of varieties (cm/tree)
1-) Data of volume of the crownof rootstocks (m3/tree)
1-) Data of average growth rate of varieties crown (m3/tree)
1-) Data of productivity of rootstocks (dried pistachios with red shell) (kg/tree)
1-) Data of average productivity of varieties (dried pistachios with red shell) (kg/tree)
Results
Atlanticshowed the best growth of circumference of below and above of the budded area, and circumference of the budded area whereas wild pistachios showed the slowest growth. Buttum placed between these two groups, but it showed the same growth rate of Atlanticin 1988 and 1991.
Atlantic and buttum had the biggest crown volume and followed by wild type. when the productivity of varieties budded on three rootstocks were analyzed, Siirt and Ohadi showed the highest productivity per tree. Uzun variety showed the same productivity level with Siirt and Ohadi in recent years.
