Abstract The real-time detection and instance segmentation of strawberries constitute fundamental components in the development of strawberry harvesting robots. Real-time identification of strawberries in an unstructured environment is a challenging task. Current instance segmentation algorithms for strawberries suffer from issues such as poor real-time performance and low accuracy. To this end, the present study proposes an Efficient YOLACT (E-YOLACT) algorithm for strawberry detection and segmentation based on the YOLACT framework. The key enhancements of the E-YOLACT encompass the development of a lightweight attention mechanism, pyramid squeeze shuffle attention (PSSA), for efficient feature extraction. Additionally, an attention-guided context-feature pyramid network (AC-FPN) is… More >

Abstract Ellagic acid (EA) is a natural antioxidant, widely present in a lot of forms’ soft fruits, nuts, and other plant tissues, and helpful for promoting human health; however, its protective effect on postharvest fruit and improving the quality index of postharvest fruit have rarely been studied. In this experiment, the strawberries were soaked in 0, 100, 200, 300, 400, and 500 mg L⁻¹ EA, respectively, and the influential EA on fruit quality and the antioxidant system of strawberries were studied. Compared with the control, EA treatment can reduce the browning degree and rotting rate of strawberry fruit during storage and… More >

Abstract

Strawberry mottle virus (SMoV) and strawberry vein banding virus (SVBV) cause diseases on strawberry plants, but the effect of coinfection of SMoV and SVBV on the growth, development, and defense system of strawberry (Fragaria × ananassa Duchesne) remains unknown. We investigated the effect of SMoV and SVBV co-infection on strawberry cultivar ‘Benihope’. The results showed that stem diameter, leaf size, leaf number, relative chlorophyll content, total chlorophyll content, photosynthetic parameters, and stomatal aperture of SMoV and SVBV co-infected strawberry (VIS) plants were in a weaker level than uninfected control plants, indicating that viruses inhibited the growth and photosynthesis of strawberry… More >

Abstract It was rarely reported about strawberry vein banding virus (SVBV) genome sequence in China and most countries worldwide. In this work, we determined the complete genome sequences of two SVBV isolates in China, designated SVBV-AH and SVBV-BJ, that were obtained from naturally infected strawberry samples from Anhui province and Beijing city of China, respectively. The complete genomes of SVBV-AH and SVBV-BJ were 7,862 nucleotides (nts) and 7,863 nts long, respectively, and both constituted with seven genes typical of the caulimoviruses. Alignment of complete nucleotide sequences showed that SVBV-AH and SVBV-BJ shared a significant nucleotide sequence identity of 97.7% of each… More >

Abstract Fruit processing devices, that automatically detect the freshness and ripening stages of fruits are very important in precision agriculture. Recently, based on deep learning, many attempts have been made in computer image processing, to monitor the ripening stage of fruits. However, it is time-consuming to acquire images of the various ripening stages to be used for training, and it is difficult to measure the ripening stages of fruits accurately with a small number of images. In this paper, we propose a prediction system that can automatically determine the ripening stage of fruit by a combination of deep neural networks (DNNs)… More >

Abstract Strawberry mottle virus (SMoV) is one of the most common viruses infecting strawberries, causing losses to fruit yield and quality. In this study, 165 strawberry leaf samples were collected from six provinces of China, 46 of which tested positive for SMoV. The complete genome sequences of 11 SMoV isolates were obtained from Liaoning (DGHY3, DGHY16-2, DGHY17, DGHY20-2, DGHY21, DGHY26-2), Shandong (SDHY1, SDHY5, SDHY31-2, SDHY33-2), and Beijing (BJMX7). The RNA1 and RNA2 nucleotide identities between the 11 Chinese isolates were 95.4–99.3% and 96.3–99.6%, respectively, and they shared 78.4–96.6% and 84.8–93.5% identities with the available SMoV isolates in GenBank. Recombination analysis revealed… More >

Abstract Auxin signaling and its components (Auxin/Indole-3-Acetic Acid (Aux/IAA)) are critical for plant growth and development. Here, we performed a genome-wide annotation and identified twenty-one Aux/IAA genes in strawberry (Fragaria vesca). Most FveIAAs were located on chromosomes 1, 2, 4, 5, and 6, while no FveIAAs were found in chromosomes 3 and 7. Phylogenetic analysis divided these genes into nine subfamilies. Most FveIAAs contained the DNA-binding and Aux/IAA domains, as well as motifs I–IV. There were 2–6 exons in the FveIAA genes based on the gene structure analysis. Also, we found that four pairs of FveIAA genes underwent segment duplications. Moreover,… More >

Abstract In this work, nine different types of edible coating based on pectin, cellulose nanocrystals, glycerol, and essential oil of lemongrass were prepared and used to coat strawberries with a film formed directly on the surface of the coated fruit. The effects of the different edible coatings on refrigerated fruits in terms of weight loss, titratable acidity, total soluble solids, pH, and anthocyanin content was evaluated after 2 days, 4 days, 6 days, and 8 days of storage. Application of the edible coatings reduced the weight loss of the coated strawberries and the anthocyanin content. The total soluble solids content of… More >
