“…Thus, our method can be easily used to simulate these fruits. According to the botanical literature, [47][48][49] we selected the pigments involved in these experiments (Table 4). We only used our first-order kinetic model and did not consider the epidermis in the simulation.…”

The color change of plant fruit in ripening is a typical time‐varying phenomenon involving various factors. Due to its complexity and biodiversity, it is challenging to model this phenomenon. To address this issue, we take the tomato as an example and propose a botanical‐based framework considering variety, environment, phytohormone, and genes to simulate fruit color change during the ripening process. Specifically, we propose a first‐order kinetic model that integrates varietal, environmental, and phytohormonal factors to represent the variation of pigment concentrations in the pericarp. Moreover, we introduce a logistic model to describe the change in pigment concentration in the epidermis. Based on the gene expression pathway of tomato color in botany, we propose a genotype‐to‐phenotype simulation method to represent its biodiversity. An improved method is proposed to convert pigment concentrations into color accurately. Furthermore, we propose a gradient descent‐based method to assist the user in quickly setting pigment concentration parameters. Experiments verified that the proposed framework can simulate a wide range of tomato colors. Both qualitative and quantitative experiments validated the proposed method. Furthermore, our framework can be applied to more fruits.

To investigate the effects of LED white light treatment (LWT) on the storage quality of postharvest ‘Zaosu’ pears, as well as its role in maintaining fruit greenness and delaying senescence, pear fruits were treated with intermittent irradiation using LED white light for 12 h per day, with a light source distance of 30 ± 1 cm and a photon flux density of 151 μmoL/(m2·s) at 25 °C. The results showed that LWT preserved the postharvest quality of ‘Zaosu’ pear fruit by reducing weight loss and ascorbic acid degradation and promoting the ratio of sugar and organic acid. Meanwhile, LWT also substantially inhibited the respiration intensity and ethylene production during the storage process. Accordingly, the expressions of genes related to ethylene biosynthesis and signaling were reduced in LWT fruit. Notably, LWT retarded the decrease in chlorophyll content of fruit by increasing the activities of enzymes associated with chlorophyll synthase. Additionally, LWT also suppressed the chlorophyll degradation-related enzymes and their gene expressions in pear peel. These findings suggest that a moderate light irradiation can delay the de-green progress and benefit post-harvest storage of ‘Zaosu’ pear.
