#Imagej software to measure plant growth software

Foram utilizados os mГ©todos de discos foliares e software ImageJ, com as medidas do comprimento (C) e da largura (L), e a relaГ§ГЈo entre o comprimento vezes a largura (CL) em folhas da cultura do pimentГЈo, em dois ensaios com dois hГbridos, Arcade e Impacto, e correlacionar os valores encontrados pelos dois mГ©todos. O objetivo deste estudo foi desenvolver modelos polinomiais para estimar a ГЎrea foliar (AF).

The destructive method of leaf discs showed high correlation (r 2=0.99) with the non-destructive method of ImageJ (r) software.Д¬apsicum annuum ImageJ leaf discs individual leaf area nondestructive methodsДЄ determinaГ§ГЈo da ГЎrea foliar Г© importante, em estudos agronГґmicos e fisiolГіgicos, para a obtenГ§ГЈo de informaГ§Гµes sobre o metabolismo vegetal e as tГ©cnicas utilizadas devem ser simples. The integrator model for all samples and both hybrids was: LA=0.57Г—LW. Measurements of length and width of leaves presented adjustment to quadratic model r 2=0.93 and r 2=0.91, respectively. The variable that best estimated LA was the relationship between LW with linear model (r 2=0.98). Regression analysis of LA versus measures L, W and LW were performed by linear and quadratic models. Through a random sampling, 560 leaves from each hybrid were selected, at different stages of crop growth.

The methods used were leaf discs and ImageJ (r) software, with measures of length (L), width (W), and relationship between length times width (LW) in leaves of the bell pepper crop in two field trials with two hybrids: Arcade and Impacto, as well as, the correlation of values found when using the two methods. This study aimed to develop polynomial models to estimate leaf area (LA). The leaf area determination are extremely important in agronomic and physiological studies, as they provide valuable information in vegetable metabolism, methods used for this purpose should be accurate.
