ÁREA DE CLADÓDIO DA PALMA Opuntia Stricta UTILIZANDO DIMENSÕES LINEARES

Abstract: RESUMOA palma forrageira Orelha de Elefante Mexicana possui elevada adaptação ao clima quente, tolerância à seca, e apresenta boa aceitação pelos animais. Objetivou definir o melhor modelo para estimativa da área de cladódio do clone Orelha de Elefante Mexicana, de forma não destrutiva, com base nas dimensões lineares do comprimento e da largura do cladódio e área da elipse. Os modelos foram avaliados pelo coeficiente de determinação do modelo, soma de quadrados dos resíduos e critério de informação de Akaike.… Show more

“…Several studies using linear dimensions in the estimation of the cladode area of cactus forage have been established for several species of the genus Opuntia: O. ficus-indica (Cortazar & Nobel, 1991;Reis, Gazarini, Fonseca, & Ribeiro, 2016) and O. stricta (Lucena, Leite, Simões, Simões, & Almeida, 2018b) and have generated equations with high precision.…”

“…Correlations between morphometric characteristics of forage cactus cladodes are known to be positively correlated, a fact that can be found in the reports of Cunha et al (2012) Little Sweet clone, Lucena et al (2019a) in N. cochenillifera Giant Sweet clone (r > 0.95), Lucena et al (2018a) in Opuntia stricta ( = 0.90), Reis, Gazarini, Fonseca, and Ribeiro (2018), ( = 0.95) in Opuntia ficus-indica correlating real cladode area with product of length by width and Guimarães, Donato, Azevedo, Aspiazú, and Silva Junior (2018) in Opuntia ficus-indica verified a positive correlation of weight with the cladode area of 0.86. Fisher's discriminant function was defined by Equation 8:…”

“…Evaluations were performed 1200 days after planting (DAP). To determine the cladode length (L; cm), width (W; cm), thickness (T; mm), area (ACR; cm 2 ) and weight (Wg; g), a randomized collection of 1018 cladodes (190 primary; 186 secondary and 205 tertiary of Little Sweet clone) and (167 primary; 127 secondary and 143 tertiary of Giant Sweet clone), free of damage, diseases or pests, was conducted according to methodologies established in the literature (Leite et al, 2017;Lucena et al, 2018a;Lucena et al, 2019a). The cladodes were numbered from 1 to 1018 and then measured using a digital calliper; the length (L; cm), width (W; cm) and thickness (T; mm) of each cladode were also recorded.…”
