DETERMINATION OF POLLEN GRAIN VIABILITY AND GERMINATION LEVELS FOR PISTACHIO AND TEREBINTH IN AYDIN /TURKEY ECOLOGY

GONCA GÜNVER-DALKILIÇ^1* AND ÖZDEN DAYI-DOĞRU²

Abstract: With this research, the viability levels, production potentials, and storage periods of pollen of naturally grown four male terebinth types (Pistacia terebinthus L.) and four male pistachios (Pistacia vera L.) grafted on terebinth trees were determined in Uzunlar Village, Atça District, Aydın Province. For the aim of determining the pollen viability levels, TTC, IKI, and safranine solutions were used. The viability ratio ranged between 88.24% (safranine test) and 70.18% (TTC test) in pistachio trees, between 85.36% (IKI test) and 63.73% (safranine test) in terebinth types. The average amount of pollen within a flower resolved by hemacytometric method was changed between 135 000 and 176 250 depend on species and types. While the germination percentage of pollen of pistachio trees and terebinth types was 71% and 26%, respectively in the beginning of storage, that of pollen in the room conditions after 4^th day, in the refrigerator from 10^th day and in the deep freezer from 2^nd month was decreased to zero.
