Meyve içinde ve dışında kuru soğukta katlanan yayılıcı dağ muşmulası tohumlarında çimlenme üzerine giberellinin etkisi
Abstract
Yayılıcı dağ muşmulası tohumları derin dinlenme gösterir ve çimlenme oranı da çok düşüktür. Bu çalışmada, yayılıcı dağ muşmulası (Cotoneaster horizontalis Decne.) tohumları katlanmadan (kontrol) ve 30, 60, 90, 120 ve 180 gün +4°C’de meyve içinde ve meyveden çıkarılarak kuru soğukta katlandıktan sonra 0ppm (kontrol) ile 500, 1000 ve 2000 ppm GA3 ile muamele edilmiştir. Soğukta katlanarak gibberellin uygulanan tohumlar +24°C’lik alttan ısıtmalı tavalardaki torf ortamına ekilerek çimlenme (çıkış) oranı, yaşayan bitki oranı (%), bitki boyu (cm) ve yaprak sayısı tespit edilmiştir. En yüksek çimlenme oranı %35.00 ile soğukta katlanmadan 2000 ppm GA3 uygulandıktan sonra ekilen tohumlardan elde edilmiştir. Bu tohumlar oda şartlarında ekim-mayıs arasında meyve içinde bekletilmiştir. Meyve içinde 60 gün +4°C’lik kuru soğukta katlandıktan sonra 1000 ppm GA3 uygulandıktan sonra ekilen tohumlardaki çimlenme oranı ise %25.00’e kadar çıkabilmiştir. Meyveden çıkarılarak kuru-soğukta farklı sürelerde katlanan tohumlarda çimlenme üzerine GA3 uygulamaları ise etki etmemiştir.

Effects of external gibberellin on germination of wall-spray cotoneaster seeds stratified with and without fruit under dry-cold conditions
Abstract
Wall-spray cotoneaster (Cotoneaster horizontalis Decne.) seeds show deep dormancy and have a very low germination rate. Wall-spray cotoneaster seeds were dry cold stratified (+4°C) either in the fruit or removed from the fruit for different periods (0, 30, 60, 90, 120 and 180 days) and then treated with different GA3 doses (0, 500, 1000 and 2000 ppm) and sown in peat medium in bottom heated (+24°C) trays in the greenhouse in the current study. The effects of GA3 treatment on germination (emergence) rate, living plant rate (%), plant height (cm) and leaf number were determined. The highest germination rate (35.00%) was obtained from the seeds treated with 2000 ppm GA3 without cold stratification. These control seeds were kept in fruit between October and May under room temperature. The germination rate in the seeds treated with 1000 ppm GA3 after stratification in dry cold at +4°C for 60 days in the fruit was only 25.00%. The GA3 applications did not affect the germination rate of the seeds that were taken out of the fruit and stratified in dry-cold for different periods.
