Citrus fruits are among the most consumed fruits by Brazilians, being grown in practically all states. Phenotyping has been associated with non-destructive optical analysis of plant characteristics, due to the use of images. The present study had the objective of estimating the morphological characteristics of Pera Rio orange fruits (Citrus sinensis) acquired in the local trade of Alta Floresta through traditional methods and using the Tomato Analyzer softwer. Measurements were made regarding length and width with the aid of a digital caliper, fruit mass using a digital precision analytical balance, total soluble solids content (ºBrix), skin thickness and height of the endocarp. The volume was also measured using the water column displacement method (VDCA), estimated diameter values with the Tomato Analyzer program, the correlation between the volumes was performed, and regression model estimates were performed based on the SigPlot program. . It was found that there was a correlation between volume estimation by the water column displacement method (VDCA) and fruit volume using the diameter estimated by the digital image (IPV), revealing that the R2 correlation coefficient was 0.80. Through the obtained results it is possible to state that the Tomato Analyzer is efficient to evaluate the volume of orange Pera Rio fruits, being able to be indicated to characterize other citrus fruits.

Optical sensor data can be used to determine changes in anthocyanins, chlorophyll and soluble solids content (SSC) in apple production. In this study, visible and near-infrared spectra (729 to 975 nm) were transformed to SSC values by advanced multivariate calibration models i.e., partial least square regression (PLSR) in order to test the substitution of destructive chemical analyses through non-destructive optical measurements. Spectral field scans were carried out from 2016 to 2018 on marked ‘Braeburn’ apples in Southwest Germany. The study combines an in-depth statistical analyses of longitudinal SSC values with horticultural knowledge to set guidelines for further applied use of SSC predictions in the orchard to gain insights into apple carbohydrate physiology. The PLSR models were investigated with respect to sample size, seasonal variation, laboratory errors and the explanatory power of PLSR models when applied to independent samples. As a result of Monte Carlo simulations, PLSR modelled SSC only depended to a minor extent on the absolute number and accuracy of the wet chemistry laboratory calibration measurements. The comparison between non-destructive SSC determinations in the orchard with standard destructive lab testing at harvest on an independent sample showed mean differences of 0.5% SSC over all study years. SSC modelling with longitudinal linear mixed-effect models linked high crop loads to lower SSC values at harvest and higher SSC values for fruit from the top part of a tree.

Near infrared spectroscopy is a susceptible technique which can be affected by various factors including the surface of samples. According to the Lambertian reflection, the uneven and matte surface of fruits will provide Lambertian light or diffuse reflectance where the light enters the sample tissues and that uniformly reflects out in all orientations. Bunch of researches were carried out using near infrared diffuse reflection mode in non-destructive soluble solids content (SSC) prediction whereas fewer of them studying about the geometrical effects of uneven surface of samples. Thus, this study aims to investigate the parameters that affect the near infrared diffuse reflection signals in non-destructive SSC prediction using intact pineapples. The relationship among the reflectance intensity, measurement positions, and the SSC value was studied. Next, three independent artificial neural networks were separately trained to investigate the geometrical effects on three different measurement positions. Results show that the concave surface of top and bottom parts of pineapples would affect the reflectance of light and consequently deteriorate the predictive model performance. The predictive model of middle part of pineapples achieved the best performance, i.e. root mean square error of prediction (RMSEP) and correlation coefficient of prediction (Rp) of 1.2104 °Brix and 0.7301 respectively.
