Estimativa da área foliar do meloeiro

Abstract: A cultura do melão (Cucumis melo, L.) ocupa posição de grande importância no Nordeste, principalmente no Rio Grande do Norte, devido ao seu grande potencial produtivo. Nestes úl-timos anos, a área média cultivada no Estado tem ficado ao redor de 6.000 ha e a produtividade média acima de 20.000 kg/ha, embora seja comum os grandes e médios produtores alcançarem rendimento superiore a 30.000 kg/ha.A área foliar do meloeiro é uma importante medida para avaliar a eficiên-cia quanto à fotossíntese e, consequentement… Show more

“…These findings corroborate the results of Monteiro et al (2005) and Busato et al (2010) for leaf area estimation in cotton and potato, respectively. This result differs from that found for sunflower (Maldaner et al, 2009a), melon (Nascimento et al, 2002) and jack bean , in which only the measurement of the leaf blade width, or the central leaflet in the case of jack bean, was enough to get the best models for estimating leaf area of these crops.…”

“…Leaf area determination from linear leaf dimensions, such as maximum length and/or width, has been performed for melon (Nascimento et al, 2002), snap bean (Queiroga et al, 2003), cucumber (Nied et al, 2001), sunflower (Rouphael et al, 2007), radish among others, but it is possible to obtain simpler models with only one dimension of the leaf blade (Blanco and Folegatti, 2005;Maldaner et al, 2009a;Nascimento et al, 2002;Queiroga et al, 2003). Maldaner et al (2009b) developed a model to estimate eggplant LAI only by counting the number of leaves, but scientific studies require a higher accuracy.…”

“…The authors highlight that values of standard error of estimates (SE) found in this study were lower than the ones observed by other authors when they used estimators of leaf area in leaf morphology similar to the yacon, for example, Silva et al (1998), working with pumpkin; Nascimento et al (2002), working with melon; and by Fialho et al (2011), working with of yacon leaf area, several linear and nonlinear models were fitted between length (L), width (W) and leaf area observed (LA obs ) (data not shown).…”

“…Para determinar a área foliar utilizou-se a equação 5 (NASCIMENTO et al, 2002;FERRAZ et al, 2011 -1 ), relação entre área foliar e massa seca foliar, significando a área foliar disponível em cada grama de folha; e a razão de área foliar (RAF -cm 2 g -1 ), obtida pela área foliar e massa seca da parte aérea, relacionando a área foliar que está sendo usada pela planta para produzir 1 g de massa seca mediante a fotossíntese.…”
