It was investigated the effect of global climate change and greenhouse gases on plants which were grouped as cultivated and related information was given. As known, agricultural sector is very sensitive to the global climate change, GHGs and their interactions. Especially, this formation is very effective on flora and fauna. On the other hand, agriculture is the second largest industrial contributor to the GHGs. It is likely to get affected positively and negatively by the climate change, but negative effects are feared to be than the positives. They contribute to unwanted effect(s) through the emission of Carbon dioxide (CO2), Methane (CH), Nitrous oxide (N20), Chlorofluorocarbons(CFCs), etc. gases. Especially, from them CH4 has the highest global warming potential that is about 300 times than the potential of CO2, and about 20 times than that of the N20. According to research findings, it is being informed that the average temperature of the Earth would be rise up to (1.4–5.8 0C) by 2100, and, various agricultural ecosystems (poly, mono and mixed) including agro-forestry, agro-silvopastoral systems, landscape, aquaculture, rangelands, wetlands and fallowlands, etc. many components will affect from this at various levels. Similarly, increases in concentration of CO2 gase will increase plant growth and water use efficiency (WUE) or consumption, reduces grain filling and nutrient use-efficiency. The purpose of the paper is state of the relationships among global climate change, greenhouse gases (GHGs) and cultivated plants

Küresel iklim değişikliği ve sera gazlarının gruplandırılan kültür bitkilerine etkileri irdelenerek, bu konuda ilgili bilgiler verilmiştir. Bilindiği üzere, tarım sektörü, küresel iklim değişikliği ve sera gazları ile bunların etkileşimlerine karşı çok duyarlıdır ve özellikle bu oluşum flora ve fauna için çok etkilidir. Öte yandan, tarım, sera gazları (GHGs) açısından en büyük endüstriyel katılımcıdır ve bu oluşumun pozitif ya da negatif sonuçlarının olması olasıdır. Ancak, bu etkilerin pozitiflerinden çok negatiflerinden korkulmaktadır. Karbondioksit (CO), Metan (CH4), Nitroz oksit (N20), Klorofloro karbonlar (CFCs) gibi gazların emisyonları, söz konusu oluşuma katkı vererek istenmeyen etkileri oluşturmaktadır. Özellikle bunlardan metan (CH4) gazı, CO2’den 300; H20’dan da 20 kat daha yüksek küresel ısınma potansiyeline sahiptir. Araştırma bulgularına göre, 2100 yılına kadar (1.4-5.8 oC) yükseleceği tahmin edilen dünya ortalama sıcaklığından; aralarında (poli, mono ve karışık) olmak üzere ormancılık, agro-silvo-pastoral sistemler, peyzaj, su kültürleri (aquakültürler), çiftlikler, ıslak alanlar ve nadas alanları gibi pek çok tarımsal ekosistemin bundan değişik şekilde etkileneceği ifade edilmektedir. Benzer şekilde, CO2 gazı derişimindeki artış bitki büyümesini ve su kullanma etkinliği ya da tüketimini artıracak tane dolumu ve besin maddesi etkinliğini azaltacaktır
