“…Considering the potential of cape gooseberry fruits, it is necessary to overcome several barriers that limit their production, marketing, and export. Among these barriers are low technical development, inadequate phytosanitary management, and incomplete knowledge of the physicochemical behavior and optimal harvest points of the fruit during its growth and development from the moment of floral induction, which leads to product loss and affects the economic sustainability of producers (Garavito et al., 2021; Guevara‐Collazos et al., 2019; Minagricultura, 2019). Cape gooseberry is a climacteric fruit with a moderate–high respiration rate and high perishability with a postharvest shelf life of 2–3 weeks at room temperature (Balaguera‐López et al., 2016; Garavito et al., 2022).…”

Cape gooseberry fruits are increasingly recognized due to their excellent organoleptic and functional characteristics as a food. As the cultivation of this fruit expands, it is necessary to determine the quality characteristics and evolution of the new growing zones. This study sought to characterize the growth and development of cape gooseberry fruits, Ecotype Colombia, in the Ventaquemada region (Department of Boyacá in Colombia). For the experiments, 50 plants were taken completely at random from which 20 flowers of the middle third were selected and marked considering that 50% of the flowers were open. The selected cape gooseberry plants were 9 months old from the establishment. Samples were carried out every 5-7 days to evaluate changes in different physiological and physicochemical properties of the fruits such as equatorial diameter, weight, dry matter, respiration intensity (RI), total soluble solids (SST), titratable acidity (TA), and maturity ratio (SST/TA). Logistic and modified enzyme kinetics models were fitted to represent the change in these characteristics as a function of growth time and to establish a suitable maturity index. A rapid increase in the growth and a substantive change in the properties of the fruits were observed between 36 and 45 days after anthesis (DAA) and stabilization between 60 and 65 DAA, which constitutes the stage of physiological maturity. At this stage, fruits with a polar/equatorial diameter of 2.2-2.5 cm, 14.9% TSS, 2.2% TA, and 191.7 cm 3 CO 2 /g/d RI were obtained. Likewise, from the adjusted models, it was possible to identify these changes, especially for the relative growth rate (RGR), color index, and maturity ratio.

To develop an optimal irrigation and fertilization system for Korla fragrant pear in the Xinjiang region, the effects of water and fertilizer coupling on the quality, yield, irrigation water use efficiency (IWUE), fertilizer partial productivity (PFP), and net profits of Korla fragrant pear under the condition of limited water drip irrigation were studied through field experiments by combining multiple regression analysis and spatial analysis. A comprehensive quality evaluation model of fragrant pear was constructed using the principal component analysis, and 12 quality indices were evaluated comprehensively. The experiment adopted a two-factor crossover design with three irrigation levels (W1: 5250 m3 ha−1, W2: 6750 m3 ha−1, W3: 8250 m3 ha−1), accounting for 60%, 80% and 100% of the ETe (where ETe denotes evapotranspiration under sufficient water supply for crops); four fertilizer application levels (F1: 675 kg ha−1, F2: 750 kg ha−1, F3: 825 kg ha−1, F4: 900 kg ha−1), designated F80%, F90%, F100%, and F110%, respectively; and 12 treatments. The results showed that the overall quality of fragrant pear was improved based on the integrated quality of pear. Four principal components were extracted through the fragrant pear comprehensive quality evaluation model, and their cumulative contribution was 89.977%; the best comprehensive quality was obtained in the W3F2 treatment and the worst comprehensive quality in the W1F1 treatment. The spatial analysis showed that when the irrigation range is 7484–8250 m3 ha−1 and the N-P2O5-K2O fertilization range is (181-223-300)–(200-246-332) kg ha−1, the comprehensive quality, yield, IWUE, PFP, and net profits of fragrant pear can reach > 85% of the maximum value. These results provide a scientific basis for water and fertilizer management of fragrant pear orchard with drip irrigation in Korla, Xinjiang.

“…To describe the relationship between temperature and respiration rate can be done by applying a mathematical model based on the Arrhenius model. The Arrhenius model in predicting the respiration rate of fruits has been investigated by other researchers [26], [28], [32], [33]. Nevertheless, the modeling respiration rate as a function of temperature and relative humidity (RH) is still limited.…”

The respiration rate of fruits is influenced by the temperature and relative humidity (RH) of the surrounding air. This research aims to determine the effect of storage air temperature and RH on the respiration rate of the coated banana. In this work, the bananas were coated with a combination of sago starch and cellulose nanofiber then was measured the respiration rate. The respiration rate was investigated using a closed system at three different temperatures namely 10°C, 17.5°, and 27°C, and three levels of RH that are about 70%, 80%, and 90% during 10 days of storage. Changes in oxygen and carbon dioxide concentrations were measured daily. The respiration rates of the coated banana (O2 consumption (RO2) and CO2 production (RCO2)) and the RQ value was influenced by storage time, storage temperature, and the interaction of those two factors. RH was found to have no significant effect on these three parameters. The Arrhenius equation was found to be suitable for the RO2 and RCO2 model and can be used to predict RO2 or RCO2 of the coated banana under real conditions for RH ranging from 70% to 90% and storage temperature ranging from 10°C to 27°C.
