Özet
Amaç: Bu çalışma, arttırılmış sıcaklık ve karbondioksit seviyelerinin arsız zaylan (Ambrosia artemisiifolia L.)’nın tohum çimlenmesi ve bitki gelişimi üzerine olan etkisini belirlemek amacıyla yapılmıştır. Yöntem ve Bulgular: Çalışma 2019 yılında tam otomasyonlu sıcaklık ve karbondioksit uygulama serasında yürütülmüştür. Çimlenme parametreleri olarak; Gmax, T50, T90, GUI75-25, GUI90-10 değerleri, bitki gelişim parametreleri olarak ise bitki uzunluğu, kök uzunluğu, bitki yaş ve kuru ağırlığı, kök yaş ve kuru ağırlığı hesaplanmıştır. Yapılan çalışmalar sonucunda sıcaklık ve karbondioksit artışının A. artemisiifolia’nın çimlenme gücünü azalttığı, sıcaklık artışının ise çimlenme süresini yüksek oranda düşürdüğü belirlenmiştir. Bitki ve kök uzunluğunda ise sıcaklık ve karbondioksit artışının olumlu etki gösterdiği ancak, bu artışın istatistiksel olarak önemli olmadığı saptanmıştır. Ayrıca, bitki ve kök yaş ve kuru ağırlığında artışların olduğu ve bu artışların istatistiksel olarak önemli olduğu (bitki kuru ağırlığı dışında) belirlenmiştir. Sıcaklık X karbondioksit interaksiyonunda ise bitki gelişim parametrelerindeki artışlarda en iyi etkinin 29 °C X 800 ppm de olduğu saptanmıştır. Genel Yorum: Sıcaklık ve karbondioksit artışı ile bitkinin çimlenme gücünün olumsuz yönde etkilenerek sırasıyla % 48,48 ve % 38.71’lik bir azalma belirlenmiştir. Ancak sıcaklık artışı ile çimlenme süresinin, bitki gelişim parametrelerinin olumlu yönde etkilendiği belirlenmiştir. T50 değerinde % 44.78, T90 değerinde % 50’ lik bir azalmanın olduğu saptanmıştır. Sıcaklık ve karbondioksit artışının bitki uzunluğunu sırasıyla % 18.54 ve % 19.76, kök uzunluğunu % 7.42 ve % 9.83, bitki yaş ağırlığını % 52.20 ve % 47.38, kök yaş ağırlığını % 107.68 ve % 209.53, bitki kuru ağırlığını % 113.34 ve % 50.91 ve Kök kuru ağırlığını % 625.41 ve % 315.80 oranında arttırdığı hesaplanmıştır. Çalışmanın Önemi ve Etkisi: Elde edilen sonuçlar doğrultusunda artan sıcaklık ve karbondioksitin istilacı türlerin yüksek bitki ağırlığı ve hızlı gelişmesini teşvik ettiği ve bunun sonucu olarak da bu bitkilerin istila potansiyelini arttırabileceği ortaya çıkmaktadır.
Aims: This study was conducted to determine the effect of increased temperature and carbon dioxide levels on the seed germination and plant growth of common ragweed (Ambrosia artemisiifolia L.). Methods and Results: The study was carried out in a fully automated temperature and carbon dioxide application greenhouse in 2019. As germination parameters; Gmax, T50, T90, GUI75-25, GUI90-10 values, and plant height, root length, plant fresh and dry weight, root fresh and dry weight were calculated as plant growth parameters. As a result of the studies, it was determined that the increase in temperature and carbon dioxide decreased the germination power of A. artemisiifolia, while the increase in temperature significantly reduced the germination time. It was determined that the increase in temperature and carbon dioxide had a positive effect on plant and root length, but this increase was not statistically significant. In addition, it was determined that there were increases in plant and root fresh and dry weight and these increases were statistically significant (except plant dry weight). In temperature X carbon dioxide interaction, it was found that the best effect on the increase in plant growth parameters was at 29 ° C X 800 ppm. Conclusions: With the increase of temperature and carbon dioxide, the germination power of the plant was negatively affected and a decrease of 48.48% and 38.71%, respectively, was determined. However, it was determined that the increase in temperature and the germination period positively affected the plant growth parameters. It has been determined that there is a 44.78% decrease in T50 value and 50% decrease in T90 value. The increase in temperature and carbon dioxide increased plant length 18.54% and 19.76%, root length 7.42% and 9.83%, plant fresh weight 52.20% and 47.38%, root fresh weight 107.68% and 209.53%, plant dry weight 113.34% and 50.91%, root dry weight It has been calculated that it increased its weight by 625.41% and 315.80%. Significance and Impact of the Study: In line with the results obtained, it is revealed that increasing temperature and carbon dioxide encourage the high plant weight and rapid growth of invasive species and consequently increase the invasion potential of these plants.
