“…Barreto et al (2017) found opposite results, i. e., pulp and rind firmness did not show any difference when distinct doses of N were applied, but values of these variables decreased after cold storage followed by simulated commercialization. Therefore, fruit firmness depends on other factors, such as the cultivar, weather conditions, plant management (irrigation), fruit orientation in the plant and exposure to sunlight (ALCOBENDAS et al, 2013), besides cold storage (ANDRADE et al, 2015).…”

“…Dolinski et al (2018) observed that peach color was not altered by N fertilization in the first two crops; changes only happened in the third crop, when high chromaticity was found at 214 Kg N ha -1 . Alcobendas et al (2013) state that fruit color is influenced by other factors, such as interaction between irrigation and exposure to sunlight.…”

“…Similar results were found by Dolinski et al (2005), who, in three crops, did not find any effect of N fertilization on soluble solid contents when peaches were harvested, and by Vashisth et al (2017), who observed that soluble solid contents in 'Tropic Beauty' peaches were not affected by N fertilization. This variable has been associated with the location of fruits in the plant, light penetration into the crown, type of twigs, thinning (PICOLOTTO et al, 2009), water absorption by plants as a response to different amounts of rainfall -which can cause sugar dilution in fruits (BRUNETTO et al, 2007) -and interaction between irrigation and exposure to sunlight (ALCOBENDAS et al, 2013).…”

Nitrogen, which is considered the most important nutrient for peach trees, may interfere in both quantitative production characteristics and quality of fruits. This study aimed at evaluating the effect of the combination of doses of N fertilization and different periods of cold storage on physico-chemical and phytochemical characteristics of peaches in post-harvest. The experiment had a randomized complete block design in a 4x3 factorial scheme, i. e., four doses of fertilization (0, 60, 120 and 180 Kg N ha-1) and three periods of storage (on the harvest day, on both the 15th and the 30th storage days at 1±1ºC, each followed by a day of simulated commercialization at 20±1ºC). The following aspects were evaluated in fruits yielded by peach trees of the genotype Cascata 1067: fruit color, soluble solid content, titratable acidity, pulp firmness, mass loss, total phenolic compounds and antioxidant activity. Different periods of cold storage and doses of N fertilization were found to affect epidermis luminosity, pulp firmness and titratable acidity of fruits. Peaches may be stored at low temperatures for 15+1 days. After that, loss of fruit firmness increases. N fertilization affects neither the soluble solid content nor the epidermis color of peaches, but both parameters are influenced by storage. Values of phenolic compounds and antioxidant activity decrease when there is N increment in the soil and when longer storage is carried out. Results suggest that peach composition may be affected by cultural practices, such as N fertilization, in harvest and after storage.

“…In addition, there was a strong positive correlation between the nut weight and the nut quality parameters. Alcobendas et al [40] also found significant correlations among peach fruit quality parameters, although the correlation coefficients were small. Lin [31] reported that there was also a correlation between Ca concentration and chestnut yield (0.613).…”

There are considerable differences in chestnut yield and quality across different chestnut-producing regions in China, indicating that environmental factors affect these properties of chestnuts. Furthermore, nut yield and quality differ depending on canopy position. Therefore, this study investigated the relationship between the canopy microclimate, nut yield, and quality. We determined microclimate factors from blossoming to ripening at different positions in the canopy. Nut yield and quality and the number of different branch types were measured at various canopy positions. The light intensity and temperature of the different canopy layers exhibited funnel-form distributions ranging from 0 to 3600 μmol·m2·s−1 and from 32 to 37 °C, respectively. Canopy humidity showed an inverted funnel-shaped distribution ranging from 26% to 40%. Nut yield and quality in the top and outer canopies were higher than in the bottom and inner canopies. Branches in the top-middle and peripheral parts of the canopy also produced higher yields, especially strong branches that bore more nuts. Nut yield and quality had positive correlations with light intensity (r = 0.735) and temperature (r = 0.709), whereas they were inversely associated with humidity (r = −0.584). The nut yield was more than 200 gm−3 when the light intensity was above 1500 μmol·m2·s−1, the temperature was above 34.4 °C, and the humidity was below 27.5%.

“…Environmental, nutritional and production management differences result in each fruit having a unique size, mass, and shape. [6][7][8][9] Taking this natural variability into account is a key obstacle to engineering efficient processes in the horticultural industry, with larger design tolerances being required to operate competently compared with other industries, driving up costs. [10] Commercially, variances in size and shape are typically managed in the sorting and packing processes, where morphological defects are removed and produce is electronically sorted into mass ranges.…”

In this paper, a new shape equation for Hayward kiwifruit is developed. Being simple and generic, it required only the major measurable dimensions of a kiwifruit as inputs (length, major-diameter, and minor-diameter). The equation was validated against empirical shape data with a maximum 3.09% error. The new shape equation can estimate important metrics, such as volume, mass and surface area. Equation development was generalized, so shape equations for other crops could be produced using the same methodology. The simplicity and speed of this new method allow realistic populations of Hayward kiwifruit to be rapidly generated in a modeling environment. ARTICLE HISTORY
