Plant Responses to ElevatedCO2

Abstract: Carbon dioxide (CO 2 ) has two unique properties: physically it absorbs in the infra‐red (heat) portion of the spectrum, and plays a role in maintaining global surface temperatures; secondly, it is the source of carbon for plant photosynthesis and growth. Recent, rapid anthropogenic increases in CO 2 have been well‐characterised with respect to climatic change; less recognised is that increase in CO 2 will also impact how plant… Show more

“…Biochemistry. Rising [CO 2 ] or temperature can increase photosynthesis, alter enzymatic activity and affect pigment production (Barnaby and Ziska, 2012). A number of herbicide sites of action are, in turn, specifically designed to disrupt these biochemical processes.…”

“…However, the degree of stimulation will differ within and between plant species. Increasing [CO 2 ] can alter the concentration and efficacy of ribulose‐bis‐phosphate carboxylase‐oxygenase, as well as stomatal number and aperture with subsequent effects on leaf photosynthesis, respiration and overall growth and fecundity (Barnaby & Ziska, ). The physiological impacts of rising [CO 2 ] may, in turn, influence not only individual plant performance, but also population success and species demographics (Radosevich et al ., ).…”

“…Esses efeitos demonstram a importância e a influência da concentração do CO2 para planta, uma vez que o CO2 atmosférico é substrato para a fotossíntese, processo no qual as plantas transformam a energia luminosa em energia química, sintetizando compostos carbonados, os quais serão utilizados em diversos processos do metabolismo vegetal (Barnaby & Ziska, 2012). Dessa forma, o incremento de CO2 atmosférico, resulta no aumento da taxa fotossintética das folhas, devido à alta concentração de CO2 no sitio ativo da ribulose-1,5-bisfosfato carboxilase oxigenasse (Rubisco).…”

“…Entre as variações climáticas, a concentração de dióxido de carbono (CO2) atmosférico se tornou uma problemática a ser estudado pela comunidade cientifica, devido ao seu constante aumento na concentração atmosférica, nos últimos dois séculos (Barnaby & Ziska, 2012;IPCC, 2014). Os resultados obtidos nas pesquisas têm demonstrado aumento na taxa de crescimento e produtividade das plantas, principalmente como consequência da estimulação da fotossíntese (Barnaby & Ziska, 2012;Misra & Chen, 2015;Liu et al, 2017).…”
