LEAF NUTRIENT STATUS OF ‘TRAKYA İLKEREN’ GRAPE VARIETY (Vitis vinifera L.) IN DIFFERENT PHENOLOGICAL STAGES

Abstract:

Nutrition of grapevines is very sensitive issue in vineyards. Soil quality is very important matter for growth and quality in vine growing. Rootstocks affect the growth and productivity of grapevine as well as increase or decrease of the nutrient uptake. The present study was conducted to determine the phenological changes of nutrient uptakes in 10 years ‘Trakya İlkeren’ grape variety (Vitis vinifera L.) in the heavy clay soil conditions. The grapevines are grown on 5BB and 5C rootstocks. The changes of macro and micronutrients in leaf blades from bud burst to post harvest period were investigated in the experiment. Leaf nutrient contents of leaf blades show varied depending on the phenological stages and rootstocks (P < 0.01 and P < 0.05). Nitrogen and phosphorus content of leaf blade was decreased until veraison stage for both rootstocks. The highest potassium (K) content was obtained at blooming stage. In blooming stage nitrogen (N), phosphorus (P), potassium (K) and magnesium (Mg) nutrients was found high on 5C rootstock whereas calcium (Ca) was high on 5BB. Grapevines were found insufficient for P, K and Mg nutrients in the study. Total chlorophyll and chlorophyll a/b ratio showed significantly varied among to rootstocks and phenological stages (P < 0.01). While the highest leaf chlorophyll content was measured during flowering period it was found at the lowest through to harvest on both rootstocks. Overall total chlorophyll contents and chlorophyll a/b ratio were significantly higher on 5BB grafted vines. In the research, 5C was found to be more successful rootstock than 5BB for nutrient uptakes.
