In this study, pollens of Burdur dimriti, Sariemin, Tilki kuyrugu, Razaki, Buzgulu, Siyah buzgulu, and Siyah gemre table grape varieties (Vitis vinifera L.) grown in Isparta, Turkey were tested in vitro for viability, germination capability, and production level. It was determined that active pollen levels varied between 23.8 % and 80.8 % in FDA (flourescein diacetat), 31.5 % and 68.8 % in TTC (2,3,5-triphenyl tetrazolium chloride) tests. In respect to pollen germination rates, the best medium in hanging drop method and saturated petri method were 20 % sucrose concentration and 1 % agar+15 % sucrose solution, respectively. The highest and the lowest pollen production levels per flower were determined 9000 in Siyah gemre and 2906 in Siyah dimrit grape varieties, respectively. |
