Última Total leaf area of papaya trees estimated by a nondestructive method Scientia Agricola Posse,Robson Prucoli; Sousa,Elias Fernandes de; Bernardo,Salassier; Pereira,Messias Gonzaga; Gottardo,Romildo Domingos. Leaf area estimation is an important feature in physiological research involving predominantly photosynthesis, transpiration and growth. This study was carried out to develop a practical and nondestructive empirical mathematical model to estimate the area of one leaf and the total leaf area for papaya trees (Carica papaya L.). Two irrigated commercial orchards were evaluated over a period of 50 to 550 days after transplanting, during which the length of the leaf midrib (LM) varied from 0.04 to 0.60 m. A mathematical model was developed to estimate the area of one leaf for the papaya tree, taking into account LM and the age of the plant measured in days after transplanting. The model was considered satisfactory. Based on the average length of the last two...

Scientia Agricola Sousa,Elias Fernandes de; Araújo,Marilaine Campanati; Posse,Robson Prucoli; Detmann,Edenio; Bernardo,Salassier; Berbert,Pedro Amorim; Santos,Paulo Albernaz dos. Leaf area has significant effect on tree transpiration, and its measurement is important to many study areas. This work aimed at developing a non-destructive, practical, and empirical method to estimate the total leaf area of green dwarf coconut palms (Cocos nucifera L.) in plantations located at the northern region of Rio de Janeiro state, Brazil. A mathematical model was developed to estimate total leaf area values (TLA) as function of the average lengths of the last three leaf raquis (LR3), and of the number of leaves in the canopy (NL). The model has satisfactory degree of accuracy for agricultural engineering purposes. Tipo: Info:eu-repo/semantics/article Palavras-chave: Canopy structure; Mathematic model; Estimating model.
