The application of biochar may enhance the properties of the soil and lessen the harm that salt stress causes to plants. In this study, we used the cuttings of <em>Melissa officinalis</em> as experimental materials. The method of pot experiment was used to explore to explore the effects of different concentrations of biochar (0, 10 %, and 20 % w/w) on soil properties and plant physiological characteristics under salt stress (0, 0.20 %, and 0.60 % NaCl+Na₂SO₄). The results indicate that the physicochemical properties of soil and the plant growth were decreased impacted with increasing salinity level, and these negative impacts were decreased traits were improved with the application of biochar. It was discovered that the application of biochar could increase the soil water holding capacity, total porosity, available P and K content, and soil enzyme activity while also decreasing the soil bulk density under salt stress. Biochar addition promoted the accumulation of plant biomass and the acquisition of nutrients, and reduced Na content in plants. With the addition of biochar, malondialdehyde (MDA) content and electrolyte leakage displayed a significant decrease under salt stress. A reduction in the osmotic substances and secondary metabolite accumulation in the leaves was also evident. The presented results reveal that biochar can contribute to protect <em>M. officinalis</em> against salt stress by alleviating the oxidative stress. Among the test samples, the 20 % biochar application had the best performance, suggesting that this is an advantageous method for improving soil properties and lessening the harm caused by salt stress on <em>M. officinalis</em>.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"338 ","pages":"Article 113704"},"PeriodicalIF":3.9,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142428738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Apple trees that have been cultivated in the same location for decades are particularly vulnerable to these environmental changes. While most of the experiments on apple fruits under climate change have been conducted using potted trees in the short term or in small chambers, we designed field-based, long-term greenhouse experiments under controlled environments to assess potential future changes in the acceptable harvesting window and fruit quality. In 2015, apple saplings grafted on M.26 rootstock were planted to establish three mini-sized populations with two rows of eight trees, each including six ‘Tsugaru’ (early maturing) and six ‘Fuji’ (late maturing) cultivars. Subsequently, in 2018, they were enclosed in independent greenhouses to keep them under ambient temperature and CO₂ concentration (GH-A), 3 °C higher and ambient CO₂ (GH-T), or 3 °C higher and 200 ppm elevated CO₂ (GH-C) before sprouting to after harvesting from 2019 to 2022. Our 4-year investigation revealed that the optimum harvesting period for ‘Tsugaru’ in GH-T and GH-C is earlier in the calendar date as is the spring phenology, remained unchanged based on days after full bloom (DAFB) compared to GH-A. However, for ‘Fuji,’ the optimum harvesting period was judged to delay approximately 10 days in the calendar date owing to slow coloration and soluble solid accumulation, although it also experienced similar advancements in spring phenology. Additionally, it is anticipated that the acceptable harvesting window will become narrow in the future owing to the rapid softening in firmness and decrease in acid concentration. Furthermore, high temperatures in GH-T tended to result in a decrease in fresh weight, firmness, acid concentration, starch rating, and color rating for both varieties compared to GH-A. In addition, for ‘Fuji,’ very few instances of watercore were observed. However, elevated CO₂ in GH-C tended to promote fresh weight for both varieties and increase the watercore appearance for ‘Fuji,’ mitigating the effects of high temperature. No other significant trends in the fruit quality indices were observed between GH-C and GH-T. Our results suggest that the overall fruit quality will reduce under future climatic conditions.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"338 ","pages":"Article 113611"},"PeriodicalIF":3.9,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142428739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, this research was conducted to investigate the effect of fertilizing fruit trees with different integrated treatments of organic, chemical, and biological fertilizers on the correction of iron chlorosis in peach and nectarine trees and the balance of nutrients in the leaves and fruits of treated trees using three indices. Experimental treatments were applied in the form of deep-hole fertilization as follows: completely rotten manure (A), manure + urea + diammonium phosphate + Fe-EDDHA (B), manure + urea + diammonium phosphate + Fe-EDDHA + <em>Bacillus</em> (C), manure + urea + diammonium phosphate + Fe-EDDHA + <em>Thiobacillus</em> + powdered sulfur (D), and manure + urea + diammonium phosphate + Fe-EDDHA + <em>Bacillus</em> + <em>Thiobacillus</em> + powdered sulfur (E). The chlorophyll content in the leaves and N, P, K, Fe, Mn, Cu, and Zn contents in the leaves and fruits were measured during two consecutive years. The results reflected that the application of manure without using chemical and biological fertilizers in the treatment A led to a decrease in the leaf content of N, P, K, and Fe below the normal level. The use of mineral fertilizers along with organic fertilizer in the treatment B led to an increase in the levels of N, P, and Fe in the leaves. Although the addition of <em>Bacillus</em> solution to the treatment C increased the leaf content of these nutrients, they were still below the optimum level. Based on Cate-Nelson analysis of variance, the yields of 50.1 and 43.2 kg tree^-1 were obtained as critical limits to separate the high-yielding community (treatments D and E) from the low-yielding community (treatments A, B and C) in peach and nectarine trees, respectively. Nutrient balance indices (DOP, DRIS, and CND) showed that Fe and P were the most limiting nutrients in peach and nectarine leaves and fruits in the low-yielding community.

Consequently, post-harvest procedures are important in aligned with production stages and assume a pivotal role in ensuring the quality of the final product. This research investigated the repercussions of diverse drying methodologies on moisture ratio (MR) and alterations in secondary metabolites within saffron stigma. The employed drying techniques encompassed non-thermal methods (NTD) such as Shade Drying (SD) and Cold Air Drying (CD), thermal drying (TD) methods including Cabinet Dryer (CAD), and radiant drying methods, namely Infrared (IR) and Thermal Light (TL). The findings underscored that TL50 °C significantly expedites drying time, being 28.97 and 26.89 times faster than SD and CD, respectively. Notably, the preeminent apocarotenoids, Crocetin, and total Crocin were found to be sensitive to heat. Interestingly, mild heat at TL50 °C and IR50 °C resulted in a substantial augmentation of these two metabolites (<em>P</em> &lt; 0.01). Elevated temperatures adversely impacted the crucial components of crocin (<em>trans-4-GG</em>) by increasing <em>cis</em> and trans isomers (R²=0.82). The mucilage characteristics of saffron stigmas remained unaffected by the diverse drying methods. However, there was a strong correlation between mucilage and crocin content (R²=0.98). According to the evaluation indices of drying models, the Demir and Midilli functions emerged as the most fitting across a majority of TD methods, boasting R²adj values ranging from 97 % to 98 %. In NTD methods, in addition to Demir and Midilli, the Wang and Singh function exhibited superior fits, attaining the minimum AICc and the highest R²adj values ranging from 0.985 to 0.999.
