Effect of Different Storage Times and Temperatures on Pollen Viability of Hazelnut (Corylus avellana L.)
Abstract
Objective: The aim of this study is to determine the most suitable pollen storage temperature for pollen grains belonging to 2 genotyes and 2 varieties of hazelnut (Corylus avellana L.) and to determine the most suitable genotype and variety for the pollen storage process.
Materials and Methods: Pollen grains belonging to the ‘Sarı’ and ‘Yomra’ genotyes and ‘Palaz’ and ‘Kara fındık’ species of Corylus avellana L. were collected from Akçakoca/Düzce, the second standard region of hazelnut production in Turkey, and then stored at 20 °C, 4 °C and -20 °C for 45 days. Pollen viability rates at 0., 15., 30. and 45. days were determined according to the fluorescein diacetate/propidium iodide protocol.
Results: Pollen viability rates of all genotypes decreased with increasing storage time and storage temperature. Storage at 20 °C resulted in a rapid decrease in pollen viability for all genotypes. Although storage at 4 °C provides adequate viability rates for all genotypes, the most appropriate storage temperature for all genotypes has been determined as -20 °C. It was determined that the most suitable genotype for pollen storage was 'Sarı' and the most suitable variety was 'Palaz’. Among all samples, the most suitable sample for storage was found to be the 'Sarı' genotype.
Conclusion: It is thought that the obtained findings may be helpful in studies related to artificial or complementary pollination processes in hazelnut and may contribute to the analysis of the limiting factors that occur in critical vital processes such as pollination and fertilization biology of the species.
