“…7) in both of our treatments indicate higher stomatal sensitivity to D than reported by Dye and Olbrich (1993) but similar to published values in the same region (Mielke et al, 1999;Soares and Almeida, 2001) however maximum light saturated G t in this study was almost double. Marrichi (2009) also found high light saturated stomatal conductance in the Veracel and Aracruz clones a similar response g s with D. Results from this study are consistent with the work by Oren et al (1999) where they found species and stands with higher stomatal conductance at a reference D of 1 kPa exhibit a higher stomatal sensitivity to D.…”

“…However, daily, seasonal, and annual growth were likely also influenced by vapor pressure deficit (VPD; see review by Whitehead and Beadle, 2004), as evidenced by differences in photosynthesis and water use on a daily basis (e.g. Hubbard et al, 2010), by differences in genotypes responses (Marrichi, 2009;Hubbard et al, 2010), by differences in growth among years with different average VPD (e.g. Stape et al, 2008), and the key role of VPD in predicting regional patterns of growth (e.g.…”

“…Isso pode ser elucidado, ao menos em parte, pelo fato de a avaliação de crescimento ser resultante de um processo contínuo que resulta no acúmulo de biomassa, enquanto a avaliação de fotossíntese é realizada em uma ocasião pontual durante o crescimento da planta. Marrichi (2009) não encontrou relação entre crescimento das árvores de eucalipto e as taxas fotossintéticas, mostrando que nem sempre os processos estudados em nível de folha isoladamente são suficientes para explicar a produtividade das árvores. Dessa forma, a relação entre fotossíntese e produtividade pode apresentar resultados diferentes entre as espécies ou clones estudados, uma vez que a maior produtividade pode estar relacionada à maior área foliar, ao próprio potencial fotossintético e à eficiência do uso da luz (INOUE; RIBEIRO, 1988;RYAN et al, 2010).…”
