DETERMINATION OF POLLEN QUALITY AND QUANTITY IN MULBERRY (MORUS ALBA L.)
ÜMMÜGÜLSÜM ERDOĞAN
Abstract
In this study, the pollen grains of eight different mulberry types in İspir and Pazaryolu districts of Erzurum were tested for the determination of viability, germination rates, pollen production levels and morphologically homogeneity. Viability of the pollens was determined by TTC (2, 3, 5-triphenly tetrazolium chlorid) and IKI (iodine + potassium iodide) tests. Pollen germination experiments were performed with ‘Agar-plate (1%)’ method in sucrose solutions of 0, 5, 10, 15, 20 and 25% concentrations. In addition, pollen production and morphologically homogeneity were determined by the ‘Hemacytometric method’. The pollen viability of all types used in this study was obtained in high ratios. Pollen germination rates were the highest for 15% and 20% sucrose solutions. The highest pollen production level was obtained from the genotype 6. The morphologically homogeneity levels of pollens changed from 97.36 to 98.86% in types.
