Özet
The effects of self-and cross-pollinations of Italia grape cultivar (Vitis vinifera L.) on berry set, seed number per berry, viable seed rate, seed sizes, germination rate and seed germination period were investigated. For cross-pollination, Rupestris du Lot (V. rupestris), 1103 P and 140 Ru rootstocks (V. berlandieri x V. rupestris) were used as pollen sources. Variation in berry setting and seed number per berry were non-significant, while significant differences were found in other seed characteristics. The highest viable seed rate was obtained from the clusters pollinated with 1103 P (91.7%). One hundred seed weight was between 3.62 (self-pollination) and 5.76 (Italia x 140 Ru). 140 Ru and 1103 P pollens induced to produce significantly heavier seeds than other pollen sources. The germination rates of seeds were significantly higher when 1103 P and Rupestris du Lot rootstocks were used as pollinator (60.6 & 56.7%, respectively). The pollen sources had also significant effects on seed width, height and thickness of Italia. The highest seed width and thickness values were measured in crosses of Italia x 140 Ru (4.95 & 4.12 mm, respectively). Seed germination commenced at 12(nd) day after the seeds were put to germinate. The first germination appeared in the seeds of the crosses of Italia with rootstocks. Italia x Italia seeds began to germinate 14 days after putting into the dishes. In conclusion, pollen sources had significant effects on quantitative and qualitative characteristics of Italia seeds. (C) 2011 Friends Science Publishers
