Abstract

This study was carried out to determine the effects of different dormancy-breaking treatments including stratification, sulfuric acid scarification, dehulling and gibberellic acid (GA3), on seed germination of different Pistacia species e.g. Pistacia vera cv. Kırmızı, Pistacia vera cv. Siirt, P. khinjuk-A, P. khinjuk-B, P. atlantica, P. terebinthus and P. mutica using as rootstock for pistachio trees. Seed dormancy-breaking treatments were shelled (control), shelled + GA3, dehulled, dehulled + GA3, Sulfuric acid scarification and sulfuric acid scarification + GA3 applications in the experiment. The seeds of Pistacia species were stratified at 4 °C for 50 days after the dormancy-breaking treatments. Stratified seeds were sown in the seedling viols filled with peat in the greenhouse to determine the germination percentage. The highest germination rate was obtained from sulfuric acid scarification in P. khinjuk-A (96.7%), and followed by dehulled application of P. vera cv. Kırmızı and P. mutica species with 94.6% and 93.2%, respectively. On the other hand, the lowest seed germination was observed for shelled + GA3 application of P. mutica with 6.7%. When the seed germination rates of Pistacia sp. were examined, the highest germination occurred in P. vera cv. Kırmızı, and followed by P. khinjuk-B. The lowest germination rate was observed on P. atlantica.

Özet

TBu çalışma, katlama, sülfürik asitle aşındırma, kavlatma ve GA3 uygulamalarını içeren farklı tohum dinlenmesini azaltıcı uygulamaların, antepfıstığına anaç olarak kullanılan Pistacia türlerinin (Pistacia vera-Kırmızı ve Siirt çeşitleri, P. khinjuk-A, P. khinjuk-B, P. atlantica, P. terebinthus ve P. mutica) tohum çimlenmesi üzerine etkilerini belirlemek amacıyla yürütülmüştür. Çalışmada kullanılan tohum dinlenmesini azaltıcı uygulamalar; kabuklu (kontrol), kabuklu + GA3, kavlak, kavlak + GA3, sülfürik asitle aşındırma ve sülfürik asitle aşındırma + GA3’tür. Denemede kullanılan Pistacia türlerinin tohumları, tohum dinlenmesini azaltıcı uygulamalardan sonra +4 °C’de 50 gün katlamaya alınmıştır. Katlamadan çıkarılan tohumlar, serada içerisine torf doldurulmuş viyollere ekilmiştir. En yüksek çimlenme oranı, P. khinjuk-A’da sülfürik asitle aşındırma uygulamasından elde edilmiş (%96.7) ve bunu P. vera-Kırmızı ile P. mutica’da kavlatma uygulaması izlemiştir (%94.6 ve %93.2). En düşük tohum çimlenmesi ise P. mutica’nın kabuklu + GA3 uygulamasında (%6.7) görülmüştür. Pistacia türlerinin tohum çimlenmesi tür bazında incelendiğinde, en yüksek çimlenme P. vera-Kırmızı çeşidinde görülmüş ve bunu P. khinjuk-B takip etmiştir. En düşük çimlenme oranı ise P. atlantica’da belirlenmiştir.
