DIFFERENT ROOTSTOCKS EFFECTS ON FERTILIZATION BIOLOGY PARAMETERS IN CHERRY

Abstract
The purpose of this study was to compare the fertilization biology of the ‘0900 Ziraat’ cherry cultivar on various rootstocks. In a 15-year-old cherry orchard located in the Atabey District of Isparta Province in Turkey's Western Mediterranean region, the pairings of the ‘0900 Ziraat’ cherry cultivar on Mazzard, Prunus mahaleb, Gisela 5, Maxma 14, and Maxma 60 rootstocks were studied in 2020 and 2021. For this purpose, the phenological periods of the combinations were noted, floral biometry was measured, pollen's morphological homogeneity ratios were assessed, pollen viability and pollen germination rates were calculated for pollen performances and pollen tube lengths were measured. The fruits derived from the combinations were also subjected to pomological analyses (fruit width, length, weight, etc.). In the two-year research, there was no statistically significant (p<0.05) change observed between the years for any of the parameters looked at. The oldest of all phenological eras was the Maxma series (Maxma 14, Maxma 60). The vegetative rootstocks (Gisela 5, Maxma 14, and Maxma 60) yielded the greatest values for petal leaf diameter, female organ length, and female organ breadth. The same was true for fruit length and diameter. The pollen viability of all rootstocks was excellent (more than 90%), and vegetative rootstocks performed better in terms of pollen germination and pollen tube length. The ‘0900 Ziraat’ cherry cultivar's fertilization biology characteristics on several rootstocks were examined in great depth in this study. This study needs to be supported by several rootstocks and cultivars.
