| Abstract:
This research was conducted with 62 apricot varieties grown in Malatya Horticultural Research Institute in Turkey. Pollen viability levels with TTC (2, 3, 5 triphenyl tetrazolium chloride), germination rates with agar in petri dish method (0.6 % agar + 15 % sucrose medium), levels of pollen production with Hemacytometric method and pollen tube growth in style with squashed preparation method were determined. It was found that the variety of '31 K 03' has the highest viable pollen percentage (89.34 %), while the lowest was obtained from 'Tokaloglu-Konya' (41.81 %). Germinated pollen levels ranged from 34.66 % ('Ablugoz') to 79.19 % ('31 K 03'). As a result, pollen germination rates and viability levels are in good agreement with each other. Values of pollen production per flower were ranged from 31952 ('Mahmudun Erigi') to 132600 ('07 K 11'). Out of 62 cvs or types tested, 37 cvs or types were found to be self incompatible. | |
