Resumo: Grafting is an effective measure to improve the photosynthetic rate of citrus. The light responses of photosynthesis in leaves of two-year old grafted Huangguogan (citrus cultivar Huangguogan), Huanggougan / Trifoliate (HG/PT), Huanggougan / Tangerine (HG/CR), and Huanggougan / Ziyang Xiangcheng (HG/CJ) were studied using the LI-COR 6400 portable photosynthesis system. Light-response curves and photosynthetic parameters were analyzed and fitted using the rectangular hyperbola model (RHM), the exponential model (EM), the non rectangular hyperbola model (NRHM), and the modified rectangular hyperbola model (MRHM). The results showed that: (1) Grafting can change the photosynthetic characteristics of Huangguogan, and the value of photosynthesis rate of HG/CJ is the greatest; (2) The light-response curves of net photosynthetic rate (PN), the light compensation point (LCP), and the dark respiration rate (RD) were well fitted using the above four models. The modified rectangular hyperbola was the best model in fitting the data; the nonrectangular hyperbola model was the second, and the rectangular hyperbola model was the poorest one.

As respostas leves da fotossíntese em folhas de Huangguogan (cultivar de citros Huangguogan), Huanggougan / Trifoliate (HG / PT), Huanggougan / Tangerine (HG / CR) e Huanggougan / Ziyang Xiangcheng (HG / CJ) foram estudadas usando o sistema de fotossíntese portátil LI-COR 6400.Curvas de resposta à luz e parâmetros fotossintéticos foram analisados e ajustados usando o modelo de hipérbole retangular (RHM), o modelo exponencial (EM), o modelo de hipérbole não retangular (NRHM) e o modelo de hipérbole retangular modificado (MRHM). Os resultados mostraram que: (1) O enxerto pode mudar as características fotossintéticas de Huangguogan, e o valor da taxa de fotossíntese de HG / CJ é o maior; (2) As curvas de resposta à luz da taxa fotossintética líquida (PN), do ponto de compensação de luz (LCP) e da taxa de respiração escura (RD) foram bem ajustadas usando os quatro modelos acima. A hipérbole retangular modificada foi o melhor modelo na adaptação dos dados; o modelo de hipérbole não-retangular foi o segundo, e o modelo de hipérbole retangular foi o mais pobre.UEL2020-01-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3633110.5433/1679-0359.2020v41n1p61Semina: Ciências Agrárias; Vol. 41 No. 1 (2020); 61-72Semina: Ciências Agrárias; v. 41 n. 1 (2020); 61-721679-03591676-546Xreponame:Semina.
