     Deficit irrigation can be used to improve tomato fruit quality. The semi-determinate tomato behaves like a bush tomato, with lateral shoots providing additional vegetative growth, but the response to deficit irrigation and the suitable training method have not been properly understood. Therefore, we clarify the combined effect of a training method (non-training, which omits manual plant management such as lateral shoot removal) and deficit irrigation (30–36% of field capacity) on yield, growth, and fruit quality of semi-determinate cherry tomato. Although deficit irrigation influenced non-training plants more than single-training plants (a conventional method by removing all lateral shoots) owing to the lowest midday leaf water potential, both plants showed the same levels of maximum quantum efficiency of photosystem II and fruit yield under deficit irrigation. Furthermore, non-training plants produced the highest levels of total soluble solids, glucose, fructose, citric acid, malic acid, and ascorbic acid under deficit irrigation. These observations indicated that the increased concentrations of the abovementioned components occurred as a result of water shortage in the fruit when compared with single-training plants. We conclude that non-training is suitable for semi-determinate cherry tomato cultivation under deficit irrigation, and that this method can produce high-quality fruits while mitigating manual plant management.

    Firmness is an important quality factor in strawberries. We investigated the tissue-dependent seasonal variation in strawberry firmness in epidermis, cortex, and pith tissues, and also developed statistical predictive models for the seasonal changes in firmness using environmental conditions and fruit properties. The experiment was conducted at three locations (sites A, B, and C) and in different harvesting seasons from winter (December) to spring (May) during 2 years. The fruit properties, including the total soluble solids (TSS), acidity, and fruit surface color decreased toward the end of the season (from winter to spring), with fruit harvested in April and May having the lowest values at all research sites. Similarly, the epidermis firmness decreased 0.73-fold toward the end of the season at all the research sites. The cortex firmness of site A showed a marked decrease of 0.64-fold toward the end of the season, but that of sites B and C remained at constant levels. The pith firmness tended to be higher for fruit harvested in December than in other months. We tested the training dataset using the stepwise multiple linear regression analysis to construct the statistical predictive models of firmness. The goodness-of-fit of the firmness predictive models, shown by the adjusted square correlation coefficient, was 0.47–0.54 in the model using the input data for daily mean environmental conditions several days before harvest as well as fruit properties, including fruit weight, color, and TSS. Additionally, in the regression analysis between predicted and actual values, the predictive models demonstrated accurate high performance with a low predictive error (0.06 as relative root mean square error). Thus, we concluded that strawberry firmness shows seasonal variation within the epidermis and pith tissues, and that their predictive models were of adequate accuracy and usefulness without the need for time-consuming, costly measurement equipment.

    <p> In a sustainable society, it is necessary to develop systems that produce enough food and energy while also preserving the environment. Both agricultural production for food generation and photovoltaics for renewable energy production require large, open fields. In this research study, we investigate the feasibility of combining food and energy production into a single field by examining the effects of installing photovoltaic equipment above land used for farming. We grew komatsuna, kabu, mizuna, and spinach underneath photovoltaic equipment, and investigated the influence of shading from the photovoltaic equipment on plant growth and yields during winter cultivation. As expected, both the amount of solar radiation and the air and soil temperature were lower under the photovoltaics than those under the open field. The growth rate of komatsuna, kabu, and mizuna were slower. However, yields and qualities sufficient to meet market demands remained possible with extension of the cultivation periods. Therefore, although temperature and solar radiation are reduced under the photovoltaic equipment in winter, it is nevertheless possible to produce vegetables in the farmland, providing a novel opportunity to realize an integrated agricultural system with parallel production of food and energy.</p>

    Textural properties play an important role in the appreciation and acceptance of fresh tomatoes by consumers. This study aimed to clarify whether the effect of salt stress (50 and 100 mM NaCl) on texture profiles depends on the cultivars and/or tissue types of cherry tomatoes and visually identify the interactions of texture with organoleptic and consumer sensory properties using correlation network analysis. The effect of salt stress on texture profiles differed according to the cherry tomato cultivar, stress intensity, truss, and tissue (outer pericarp, locule, septa). The cohesiveness, gumminess, and chewiness of the outer pericarp and the cohesiveness of the locule were higher in salt-stressed fruit than in control fruit, but the effect was cultivar-dependent. Sensory properties such as overall taste, sweetness, and skin hardness and several organoleptic properties were 1.2–1.7-fold higher in salt-stressed fruit than in control fruit. Although no textural properties interacted with sensory properties in the control fruit network in correlation network analysis, the connectivity of textural properties such as cohesiveness with other traits in salt-stressed fruit increased with increasing salt stress intensity. In the network combining all treatments, the most connected node was cohesiveness, and cohesiveness was the key factor that enhanced the sensory and organoleptic properties of salt-stressed tomatoes, although the effects were cultivar- and tissue-specific. Thus, correlation network analysis provided visual insights into the interactions of textural properties with organoleptic and sensory properties.
