Abstract

Quince (Cydonia oblonga Mill.) cvs. Ekmek, Esme, Limon, Ege 2, Ege 22, Ege 25 and Quince-Arootstock pollens were collected in April from the unopened pink balloon-stage flowers on maturetrees. The pollen amount was between 20063 pollen/flower ('Ege 25') and 11906 pollen/flower ('Limon')with hemacytometer. The lowest and highest pollen viability were determined from 79.8 (Quince A inday 14) to 97.8% ('Ege 2' in day 0) by IKI. The germination rates in different sucrose and boric acidconcentrations in 1% agar changed from 0 ('Limon' in 0% sucrose) to 91.7% ('Ege 2' in 20% sucrose)and from 32.7 (Quince A in 0 mg/L boric acid) to 94.9% ('Ege 22' in 100 mg/L boric acid), respectively. © 2011 Academic Journals.
