Anatomy and Pollen Properties of Merzifon Black Grape Variety (Vitis vinifera L.)

Abstract

In the study, it was aimed to determine the anatomy and pollen properties of the Merzifon Black grape variety (Vitis vinifera L.). The presence of collenchyma tissue in the stem, the presence of 4-5 cell layer vascular cambium and 3-4 layer parenchymal ray cells, open collateral formation of the conduction bundles, the presence of starch, raphide and druse crystals are important anatomical features of the stem. Leaf type is dorsiventral and stoma type is actinocytic. The stoma was observed only on the lower surface of the leaf. When the stoma index of Merzifon Black grape variety compared to other grape varieties, it was determined that it has low stoma index. Like the stem, starch grains, raphide and druse crystals were observed in the leaf. The pollen shape in the equatorial view is suboblate and in the polar view it is oblate. The pollen type is tricholporate.
