Resumo: The chlorophyll content in leaf of yellow passion fruit is usually determined by destructive methodologies. Portable chlorophyll meters make indirect measuring of leaf chlorophyll concentration possible in rapid and non-destructive way. The chlorophyll content of yellow passion fruit leaves were determined fifty times by dimethylsulfoxide extraction and estimated by the chlorophyll meter SPAD-502. Linear relations among the SPAD readings and the chlorophyll concentrations were established. The estimated chlorophyll contents were, Ya= 2.7990 + 0.3208X; Yb = -11.7934 + 1.2815X, and Yt= 9.0497 + 1.3967X, with determination coefficients (r²) of 0.9942, 0.9893, and 0.9948, respectively for chlorophyll a, b and total. It is concluded that SPAD readings had good accuracy in estimating the leaf chlorophyll concentration of the passion fruit plant, in a non-desctructive way, by linear regression models.

No entanto, a utilização do clorofilômetro portátil SPAD-502 possibilita mensurações indiretas rápidas e não destrutivas da concentração de clorofila foliar. Estudou-se a existência de relação linear entre leituras SPAD-502 e conteúdo de clorofila em folhas de maracujazeiro amarelo com extrator dimetilsulfóxido (DMSO). Cinquenta leituras SPAD foram, significativamente, relacionadas com a concentração de clorofila nas folhas de maracujá e o modelo linear de primeiro grau descreveu melhor esta relação. Quais sejam: Y 1 = 2,7990X + 0,3208; Y 2 = -11,7934X + 1,2815 e Y 3 = 9,0497X + 1,3967, com coeficientes de determinação (r2) de 0,9942, 0,9893 e 0,9948, respectivamente para clorofila a, clorofila b e clorofila total. Leituras SPAD podem ser usadas com boa acurácia na estimativa da concentração de clorofila foliar de maracujazeiro, de forma não destrutiva, através dos modelos de regressão adotados.Revista Brasileira de Agropecuária Sustentável2018-01-25T10:43:31Z2018-01-25T10:43:31Z2011-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf2236-9724http://www.rbas.ufv.br/index.php/rbas/article/view/15http://www.locus.ufv.br/handle/123456789/16796engv.1, n.1, p.74-78, July 2011Morgado, Marcos Antonio DellOrtoFialho, Gustavo SessaBruckner, Claudio HorstMelo, Luciano Átila deinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T08:42:25Zoai:locus.ufv.br:123456789/16796Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T08:42:25LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
