“…Rice is one of most important food species in world, and about 50% of world's population consumes rice as a staple food, among which more than 2 billion people in Asia rely on rice and its products as main source of calorie intake [1] . For many years, China's rice production has ranked rst in world, accounting for about 30% of world's total rice production and about 1/3 of total domestic cereal production [2] . Rice in China is mainly used in four areas: feed, seed, edible and industrial, among which edible consumption is up to 80%, and its consumption is gradually increasing with improvement of people's living standard and increase of population [3] .…”

Objective. To explore theoretical basis and feasibility of using computer image processing technology for rapid analysis of rice mold, to promote application of this technology for rice quality analysis, and to make a new exploration for safety of rice in China to realize sustainable development of rice resources in China. Methods. Four types of rice (Zhengdan 958, Xiangyu 335, Yu'an 13, and Jundan 20) were used as research materials to simulate process of rice mildew in a specific environment (temperature 25°C, humidity 60%). Then, a correlation analysis was performed with amount of bacteria and mycotoxins (aflatoxin B1, vomitoxin, rice gibberellin, ochratoxin) in rice and a discriminant model was established. A BP neural network was used to identify degree of moldiness of rice. Results. The amount of bacteria in rice samples tended to increase with time, and color of rice grains became darker and duller as mold deepened. On 41st day, sample was seriously deteriorated and experiment could not be conducted. According to amount of bacteria, four rice samples were judged to be normal on days 1-5, pre-mold on days 7-11, mid-mold on days 13-33, and post-mold on days 33. The correlation analysis showed that there was a good correlation between amount of moldy rice and some color characteristics parameters. Y=5020.67-41.661XRt+20.199X1 value, R2=0.934; modeling process of bacterial load of Yu'an 13 introduced color characteristic parameters of B, S, I, modeled as Y=-15602.569+463.54XBn+75209.492Xsm-367.105X1t, R2=0.96; Jundan 20 The modeling process of amount of bacteria carried was introduced with color characteristic parameter I, modeled as Y=2696.205-15.445X1 value, R2=0.823 .

“…Several studies have reported on microbial diversity in seeds of different plants, e.g., maize (Brito et al 2022), orchid (Gao et al 2019), cauliflower (Dhekle et al 2013), cacao (de Araujo et al 2019) lima bean (Mota et al 2017), common bean (Parsa et al 2016), and rice (Fisher & Petrini 1992). Our study looked into the microbes associated with cherry tomato seeds.…”

Healthy seeds are the foundation of healthy plants. Planting healthy seeds contributes to securing crop productivity and seed germplasm conservation. In this study, we have identified microbes associated with seeds of three cherry tomato genotypes and demonstrated their negative effect on general seed health. Through a combined morpho-cultural and molecular characterisation (using multi-loci analysis of the ITS, β-tubulin, tef1α, and gapdh gene regions for fungi and 16s rDNA for bacteria), we have identified three fungi (Nigrospora sphaerica, N. lacticolonia, and Curvularia aeria), and two bacteria (Citrobacter freundii, and Stenotrophomonas maltophilia) from healthy-looking tomato seeds. These fungi and bacteria, through seed-soaked-inoculation, caused seed discoloration, lesions, and low germination. To our knowledge, these are the first reports of Nigrospora sphaerica, N. lacticolonia, Curvularia aeria, Citrobacter freundii, and Stenotrophomonas maltophilia on tomato seeds and demonstrated their negative impact on seed health. Seed treatment and interventions are needed to negate the possible effect of these microbes. Future studies on possible seed transmission are warranted.

Postharvest management is critical to attaining household food, nutrition, and income security. Hermetic grain storage bags offer an effective pesticide‐free way to protect stored grain against fungal and insect infestation. We evaluated articles indexed in the Web of Science that included experiments comparing the storage efficacy of conventional and hermetic storage bags based on grain germination rate, insect infestation, physical damage, mycotoxin contamination, and changes in weight and moisture content. Compared with grain stored in hermetic bags, grain stored in conventional bags lost 3.6‐fold more seed viability, contained 42‐fold more insects, had 11‐fold more physical damage, and lost 23‐fold more grain weight, while grain moisture levels were similar for both hermetic and conventional storage bags. Mycotoxin contamination levels were not as frequently assessed. Levels could be low in grain stored in both types of bags, or levels could be low in hermetic bags and significantly higher in conventional bags. The improved properties of grain stored in hermetic bags can increase food security and household income by providing safe storage options for maintaining seed germinability, and for consumption and/or sale when food supplies are high, or when prices are low. Hermetic bags are economically feasible for use by subsistence farmers in Sub‐Saharan Africa for grain for household consumption and for carrying‐over seed for planting in the next season. Additional studies are needed to verify the mycotoxin contamination results and to determine if there are differences in functional food characteristics, e.g. flavor and cooking properties, that have not been as comprehensively studied. © 2023 The Authors.
