مرکز منطقه ای اطلاع رساني علوم و فناوري - Determination of Pollen Qality and Qantity of some Fruıt Species/Cultivars Grown in Erzurum Condition

Abstract :

In the research, 14 and 15-year-old trees of ‘Golden Delicious’, ‘Granny Smith’, ‘Starking Delicious’, ‘Starkrimson’, ‘Amasya’, ‘Sakı’ apple cultivars, ‘Giant’, ‘Stanley’, ‘Violet’ plum cultivars, and ‘Kütahya’ sour cherry cultivar were used as research materials. It was aimed to be determined pollen quality and quantity of the cultivars in Erzurum conditions in 2008-2009. TTC and IKI test were used to determine rates of pollen viability, and amount of pollen production was used by hemasitometrik lam in different fruit species and cultivars. Pollen germination rates was determined as 0, 5, 10, 15, 20, 25% by using sucrose concentrations At the end of a two-year research, pollen viability rates determined by IKI test was average of 96% in apple cultivars, 64% in plum cultivars and 60% in sour cherry cultivar. Pollen viability rates were determined by TTC and they were average 56% in apples, 58% in plums, 56% in sour cherry. The best germination rate was obtained from %15 sucrose concentration. The highest germination rate was reported Starkrimson (58.3%) in 2008, Amasya (62.2%) in 2009, Giant (46.26%), in 2008, Violet (55.2%) in 2009. According to a two-year average, sour cherry had 45% germination rate. Maximum pollen production per a flower was 68276 in Amasya apple cultivar, Stanley plum cultivar 54854 in Stanley plum cultivar, 25539 in sour cherry in both of the years. Morphological homogeneity was identified as average 94% in apples, 90% plums, 78% sour cherry.
