A research on Non-Destructive Leaf Area Estimation Modeling for some Apple Cultivars

A non-destructive method for leaflet area prediction of Spondias tuberosa Arruda: an approach to regression models

“…It is noteworthy that, in these equations with only L or W, there were greater practicality and speed in data collection in the field, suggesting savings in the number and time of measurements (Santos et al 2016), but they also had low precision and fit the models (Bosco et al 2012, Souza et al 2015, since it did not obtain a LA that represents the entire LA of the species. This is consistent with results found by several authors for crops such as Moringa oleifera (Macário et al 2020), Juglans regia (Keramatlou et al 2015), S. hispanica (Goergen et al 2021), and M. domestica (Boyaci and Küçükönder 2022). Pohlmann et al (2021), in a study predicting the LA of common bean (Phaseolus vulgaris), found that the equations that best fit were those with the product (LW), with R 2 above 0.94.…”

“…According to Williams and Martinson (2003), the accepted models should have R 2 greater than 0.95, indicating greater predictive capacity and lower dispersion. The results of the present study corroborate those observed for Vitis vinifera (Buttaro et al 2015), Eustoma grandiflorum (Dias et al 2022), and Malus domestica (Boyaci and Küçükönder 2022), in which the most appropriate models were the linear model without intercept and power to estimate LA.…”

“…Leaf area is among the factors that condition plant performance in natural and agricultural ecosystems, which is related to photosynthetic capacity (relative leaf growth rate, net assimilation rate, and photosynthetic efficiency), biomass production, competition, nutrition, soil-plant relationship, and, as a result, leaf area is used as a parameter in plant physiology and production (Macário et al 2020, Adji et al 2021, Boyaci and Küçükönder 2022.…”

“…Salazar et al (2018) proposed the use of the product of length and width using polynomial regressions to estimate the leaf area of cacao (Theobroma cacao L.) with a coefficient of determination of 98%, and this use is reported for several species, such as Ceiba glaziovii (Ribeiro et al 2022), Eustoma grandiflorum (Dias et al 2022), watermelon (Rouphael et al 2010), Forsythia viridissima, Ligustrum lucidum, Ligustrum sinense, Osmanthus fragrans, Syringa oblata var. alba (Shi et al 2019), and Malus domestica cultivars (Boyaci and Küçükönder 2022).…”

Non-Destructive Model for Estimating Leaf Area and Growth of Cnidoscolus aconitifolius Cultivated Using Different Stem Diameter of the Semi Hardwood Cuttings

“…The leaf thickness insignificantly contributes to the leaf surface area, except for a succulent leaf. The use of L, W, and LW for non-destructive estimation of LA has been accepted by worldwide researchers, including in arabica coffee (Mielke et al, 2023), guava (Gonçalves, Ribeiro & Amorim, 2022), apple (Boyacı & Küçükönder, 2022), and many more.…”
