Examination of pollen grain viability and germination capability by in vitro tests in some grape cultivars (Vitis vinifera L.)

This research was carried out to determine pollen grain viability and pollen germination capability of 23 grape cvs. (Gamay, Chardonnay, Pinot Noir, Bogazkere, Okuzgozu, Clairette, Cinsaut, Emir, Papaz Karasi, Alicante Bouschet, Riesling, Kalecik Karasi, Semillon, Trakya Ilkeren, Yalova Incisi, Muscat Ottonel, Hafizali, Italya, Hamburg Misketi, Tekirdag Cekirdeksizi, 2B-56, Kozak Beyazi and Cabernet Sauvignon) in vegetation period of 2003 year. While cv. Trakya Ilkeren and cv. Italya have the highest viable pollen (100%); cv. Chardonnay has the lowest pollen viability ratio (54.8%) in examined cultivars. When it was examined the ratio of pollen germination capability, cv. Chardonnay (19.675%), cv. Pinot Noir (23.450%) and cv. Gamay (30.025%) gave the lowest ratio; cv. Bogazkere (81.400%) and cv. Clairette (80.925%) have the highest ratio. The other cultivars which were examined had grain germination values which were between this ranges.
