The LAB isolates exhibited impressive resilience to gastric acid, surviving exposure to simulated gastric juice at pH 2 after 2 h of incubation. Autoaggregation and hydrophobicity, crucial for probiotic adhesion to intestinal epithelial cells, were observed in several LAB isolates.

Ehb3 and Ehb5 demonstrated outstanding antioxidant capabilities, suggesting their potential for enhancing the shelf life and health benefits of probiotic products.

This study amassed four year of field trial data from four primary maize ecological areas in China (Longitude: 89°E to 125°E, Latitude: 35°N to 44°N) to examine the relationship between plant density and MC of maize. Our analysis revealed that increasing plant density exerted an effect on the MC of maize. This effect stemmed from a combination of uncertain grain development and premature plant senescence due to overcrowding. We categorized the relationship between plant density and MC into six types: NC-Type (No-changing), I-Type (ever-increasing), L-Type (ever-lessening), V-Type (like the valley), P-Type (like the peak), and W-Type (like a wave). On average, a variation approximately 0.053 % in MC was observed when the plant population changed by 1000 plants/ha. Moreover, different maize varieties contributed to a more substantial variation in MC. Despite the negligible impact of MC variation caused by plant density on grain quality, subsequent harvest management, and industrial production of maize, there was a significant enhancement in maize yield with increased plant density.

However, whether and how greater gains in grain yield can be achieved by combining WSP with an increased plant density is unclear. In this study, two winter wheat cultivars were subjected to three plant densities (lower, normal, and higher) and two planting patterns (conventional planting [CP] and WSP). The effects of plant density, planting pattern, and their combination on the solar radiation interception and conversion, biomass accumulation, harvest index, and grain yield were investigated. In response to an increase in plant density from lower to higher and a shift from CP to WSP and their combination, grain yield increased by 15.43 %, 10.85 % and 27.62 % for cultivar Taimai198, and by 13.13 %, 8.31 % and 22.41 % for Shannong30, respectively. The larger increases in grain yield were mainly ascribed to enhanced dry matter production, in particular after anthesis with no variation or a slight decline in the harvest index. The higher plant density was the dominant driver of the enhanced radiation interception, whereas WSP was mainly responsible for ameliorating the reduction in radiation use efficiency (RUE) caused by the higher plant density. The combined effects of these two management practices in increasing grain yield were much greater than the independent effects of a shift from CP to WSP or an increase in plant density.

This study investigates the impact of long-term manure application on maize yield, the micronutrients content of grains, and grain nutritional quality in a maize-soybean rotation. Our results indicate that consistent manure application significantly enhances maize yield. Compared to the long-term chemical fertilizers only, the addition of manure increased the Fe, Mn, Cu, and Zn concentrations of the grains. In addition, the highest grain protein concentration was observed when treated with manure. Concentrations of protein fractions such as globulins, gliadins, and glutenins were found to be higher with a low manure application (13.5 t ha−1) compared to high manure application (27 t ha−1). The optimum increments in essential amino acids (EAA) and the ratios of essential to nonessential amino acids (EAA/NAA) was observed under low manure addition treatment. Collectively, incorporating manure into a long-term maize-soybean crop rotation not only escalates yields but also critically enhances the nutritional profile of maize grains through an increase in micronutrients and by promoting balance of proteins and amino acids within the grain.

Here, we conducted a two−year field experiment (2017 and 2018) to explore the effects of grazing [two stocking rates (0 and 6 sheep months ha−1)] and Se addition [six Se addition levels (0, 5, 10, 20, 40 and 80 g ha−1)] on above−ground biomass (AGB), below−ground biomass (BGB), root−to−shoot ratio (R/S), species richness and Shannon−Wiener's diversity index of an alpine meadow at the Maqu county in the Eastern QTP. The results indicate that AGB peaked at a Se addition rate of 21 g ha−1 combined with no grazing (i.e., exclosure) and at a rate of 20 g ha−1 Se addition with a stocking rate of 6 sheep months ha−1; BGB was highest under a Se addition of 23.5 g ha−1 (under exclosure) and 23 g ha−1 (under grazing). After Se addition, the species richness and Shannon−Wiener index of the alpine meadow under the grazing treatment were significantly lower than those in the exclosure treatment, which was mainly driven by the reduction of sedges and forbs.

The γ-aminobutyric acid (GABA) has been widely proved to play important roles in plants in response to abiotic stresses, showing an important potential for application in agricultural industry to overcome environmental challenges. However, application of GABA in kiwifruit plants to resist external stresses has not been reported yet. This study found that pre-irrigation of kiwifruit plants with 0.5 mM GABA was effective in alleviating the heat damage on them. GABA treatment led to better antioxidant capacity and reduced ROS production in kiwifruit plants under high temperature. Moreover, exogenous GABA protected the photosynthetic system of kiwifruit plants when exposed to high temperature. Particularly, we found that endogenous ABA, Glu, Pro metabolisms were participated in the GABA-mediated heat resistance of kiwifruit plants. Furthermore, GABA treatment induced higher expression of AdHsps in kiwifruit plants, being partly responsible for their better performance under heat stress. In summary, this research first demonstrated that exogenous GABA treatment plays a positive role in kiwifruit plants to response to extreme heat stress.</div>","PeriodicalId":54198,"journal":{"name":"Annals of Agricultural Science","volume":"68 2","pages":"Pages 137-147"},"PeriodicalIF":5.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0570178323000301/pdfft?md5=f0b83b67236591d50bfc08f693cc2ed6&pid=1-s2.0-S0570178323000301-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138577815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate the fate of applied N in the soils with organic management history, the 15NH2CO15NH2 (15N abundance of 19.6 %) was employed as the exogenous N source to conduct an experiment in the Chinese cabbage and tomato rotation system under plastic shed condition. The cultivated soils have received 15-year of effective microorganism (EM) fermented organic fertilizer (EM-OF), N, P, K inorganic fertilizer (NPK-IF) and no fertilizer (No<img>F). The 15N use by cabbage and tomato, the soil 15N forms, as well as the 15N distribution were observed. Results showed that the 15N use efficiency of cabbage in the EM-OF, NPK-IF and No<img>F soils were 55.1 %, 37.3 % and 26.6 % respectively, showing significant (p ≤ 0.05) differences. The succeeding crop tomato could take up the soil residual 15N, and the highest 15N reuse efficiency was 7.1 % that detected in the No<img>F soil. The total 15N loss (6.0 %) from the rotation system was the lowest in the EM-OF soil, compared to that in the NPK-IF and No<img>F soils. It was concluded that the long-term fermented organic fertilizer applied soils can reduce urea 15N loss from plastic shed agriculture, mainly through improving the in-season crop 15N use efficiency.</div>","PeriodicalId":54198,"journal":{"name":"Annals of Agricultural Science","volume":"68 2","pages":"Pages 108-117"},"PeriodicalIF":5.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S057017832300026X/pdfft?md5=1a200c69d441a55a459b110ea9eb25fc&pid=1-s2.0-S057017832300026X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138472658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
