Klonlar, dört farklı alanda denenmiştir. Rastlantı blokları deneme desenine göre tesis edilen deneme alanlarında klonlar, 5 blokta toplam 25 fidan ile temsil edilmiştir. Fidanlar, beş ağaçlı sıra parseli şeklinde 3,25x3,25m aralık mesafede dikilmiştir. Varyans analizi sonuçlarına göre soğuk ve gal zararından etkilenme açısından bütün deneme alanlarında klonlar arasında istatistiksel olarak önemli farklar oluşmuştur. 5.yaş sonunda, E. grandis ve melezlerin, E. camaldulensis’ten daha fazla soğuktan etkilendiği görülmüştür. Karabucak ve Ceyhan koşullarında gelişim bakımından öne çıkan E. grandis klonları (G96, G42 ve G60) soğuktan etkilenmiş olmalarına rağmen 5.yaş sonunda en fazla hacim gelişimine sahip olurken Kırıkhan koşullarında E. grandis ve melezlerin tamamı soğuktan zarar görerek sahadan uzaklaşmıştır. Diğer taraftan, etkilenme oranları bakımından farklılık olmasına rağmen bütün klonlarda gal zararına rastlanmıştır. Bulgular, uzun sürmeyen soğuklardan ve aynı zamanda gal arısından etkilemiş olmalarına rağmen daha fazla yaşama oranı ve hacim artımına sahip olan E. grandis klonları (G96, G42 ve G60) ile E. camaldulensis klonunun (C188) Karabucak ve Ceyhan yöreleri ve C298 klonunun ise Kırıkhan yöresindeki plantasyonlarda kullanılabileceğini göstermektedir.</p></abstract>

                            <p>In this study, it is aimed to evaluate Eucalyptus camaldulensis, E. grandis, and their hybrid clones in terms of being affected by cold and eucalyptus gall wasp damage in different growing environments. The clones were tested in four different areas. Clones were represented by a total of 25 seedlings in 5 blocks in the trial areas established according to the randomized block design. The seedlings were planted in a five-tree row plot at a distance of  3.25x3.25m. According to the results of variance analysis, there were statistically significant differences between clones in all trial areas in terms of being affected by cold and gall wasp damage. It was observed that E. grandis and hybrids were more affected by cold than E. camaldulensis. The E. grandis clones (G96, G42, and G60) that stand out in terms of development in Karabucak and Ceyhan conditions had higher volume development at the end of the 5th year despite being affected by cold, while in Kırıkhan conditions all E. grandis and hybrids were damaged by the cold and died. Gall wasp damage was found in all clones although there were differences in terms of the rates of involvement. Results show that having higher survival rates and volume increases despite being affected by short-term cold weather and also by gall wasps, E. grandis clones (G96, G42, and G60) and E. camaldulensis clone (C188) can be used in plantations in Karabucak and Ceyhan regions and C298 clone in Kırıkhan region.</p></trans-abstract>
