Response of Trees to CO2 Increase

摘要: Among the principal abiotic requirements for plant growth, namely, light, water, nutrients and carbon dioxide, CO2 is an anthropogenic gas associated with potential global warming. Any change in availability of above elements will impact not only plants, but entire living systems. The current annual rate increase (~0.5 %) expected to continue concentrations exceeding 600 ppm by end this century from 380 (Houghton et al. 2001). Such levels certainly affect globally important process photosynthesis, which sustains life on planet. Hence has been subject intensive research during past half a century. Since book going deal climate fruit trees, reader referred number general publications (e.g. Koch Mooney 1996; Murray 1997; Luo 1999; Reddy Hodges 2000; Karnosky 2001; Ziska Bunce 2006; Kallarackal Roby 2012). It remember that as methodology artificial enrichment experiments improving around groups concentrating research, our understanding response plants elevated changing. All methods used past, chamber Free-Air-Carbon dioxide-Enrichment (FACE) have both positive negative attributes hence data obtained through any method should be treated caution. Moreover, there much interaction other biotic factors, usually ignored many studies.
