The grapevine leaf is of utmost importance in characterization, despite its traits being very sensitive to environmental factors. In this study, the effect of irrigation/drought stress on the individual leaf morphology and morphometry of the ‘Hárslevelű’ grapevine (Vitis vinifera L.) cultivar was examined. To verify the effect of the applied irrigation methods (drip and subsoil irrigation) on the plant’s water status, water potential measurements were carried out during the 2022 season. The effect of the applied treatments on the vegetative growth was evaluated according to point quadrat and a multichannel LiDAR analysis in order to describe the width of the canopy area, row volume, and area coverage index. The individual leaf morphology was assessed via traditional morphometry and colorimetry. Our results showed that rainfed plants had a significantly lower stem ψ compared to the drip- and subsoil-irrigated plants at all examined dates. The point quadrat results indicate that the leaf layer number was significantly (p < 0.05) influenced by the position, while the treatment showed no effect on the leaf layer number. The leaf colorimetry showed a difference among the samples, as significant alterations were found in 28 out of the 32 examined color properties. Within the traditional morphometric analysis, 54 traits were evaluated, and 14 of the traits were significantly altered due to the different water management systems.","PeriodicalId":507445,"journal":{"name":"Horticulturae","volume":" 28","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141675163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess the prospects of obtaining new functional food products based on the wild form of P. oleracea L., foliar biofortification of this species with sodium selenate (VI) was carried out, and the changes in leaf and seed biochemical characteristics were investigated. Selenium significantly enhanced plant yield, photosynthetic pigments and the ascorbic acid content, and showed a tendency to seed productivity increase. The application of selenium augmented quinic acid content in leaves by 1.7 times but did not affect the oxalic acid content. Oxalic acid prevailed in wild purslane and quinic acid in cultivated purslane (cv. Makovey). Seed oil in Se-enriched purslane was characterized by a two-fold decrease in saturated fatty acids and squalene and 2.3-fold decrease in malonic dialdehyde content, along with a 1.4-fold increase in ascorbic acid. Selenium supplementation resulted in an increase in total lipids and mono- and di-unsaturated fatty acids and did not affect the concentration of ω-3 fatty acids and sterol accumulation. Among the identified sterols, only the minor ones (fucosterol, 7-stigmasterol and ∆7-avenosterol) showed a slight decrease upon Se supply. Compared to seeds of cv. Makovey, wild purslane seeds had higher levels of antioxidant activity by a factor of 2 and of polyphenols by a factor of 3.2 but did not differ significantly in oil fatty acid composition. The results indicate the importance of wild purslane leaves/seeds both fortified and not fortified with Se in human nutrition and medicine.","PeriodicalId":507445,"journal":{"name":"Horticulturae","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141679433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A field experiment with six-year-old P. avium cv. Lapins was performed under two water treatments: irrigation at 100% of crop evapotranspiration (ETc) [full irrigation (FI)] and irrigation at 60% ETc from the second fruit phase to harvest time (DI). A single 0.5 mM SA was applied to both water treatments at fruit color change. At harvest time, fruits were collected to determine yield, fruit quality, and quality during post-harvest storage (0, 10, 20, and 30 days). The DI reduced fruit yield (11%), fruit weight (8%), and caliber (6%) and increased firmness (7%) and total soluble solids (TSS) (5%) in P. avium compared with FI plants at harvest time. Our study showed that SA application recovered fruit yield (9%), fruit weight (5%), and caliber (4%), improving TSS in DI plants at day 0. Interestingly, SA application significantly reduced P. avium fruit cracking (78% in FI and 82% in DI). Fruit weight was reduced in all treatments, mainly decreasing by 14% in FI and 13% in DI plants at day 30 of post-harvest storage. Fruit weight did not change during post-harvest storage with SA, except on day 30, where a slight reduction was observed. TSS showed no significant differences during post-harvest storage for all treatments. Therefore, SA could be an interesting tool to mitigate the impact of DI on the yield and fruit quality of P. avium and to reduce fruit cracking and prolong fruit quality during post-harvest storage.","PeriodicalId":507445,"journal":{"name":"Horticulturae","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141677897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the collection, cultivation, and detailed characterization of such landraces constitute an inherent aspect of the world’s natural resource heritage. This effort holds promise for the development of elite varieties capable of thriving amidst continuous global climate fluctuations. In this context, we conducted a comprehensive assessment of the main agronomic attributes, physico-chemical properties, and functional quality traits of the major hot pepper landraces adapted to diverse climatic conditions in Tunisia. These landraces include ‘Dhirat’, ‘Semmane’, ‘Beldi’, ‘Nabeul’, ‘Jerid’, ‘Mahdia’, ‘Cayenne’, ‘Kairouan’, and ‘Baklouti’. Most of the pepper landraces exhibited satisfactory yields, ranging from 1163.25 to 1841.67 g plant−1 in ‘Jerid’ and ‘Kairouan’, respectively, indicating robust productivity, especially under prevailing climatic changes and high temperatures during both growing cycles. The levels of antioxidants comprising capsaicinoids, carotenoids, phenolics, and tocopherols, as well as radical scavenging activity, emerged as key discriminating factors among pungent pepper landraces. Irrespective of genotype, capsaicin and dihydrocapsaicin constituted the major capsaicinoids, accounting for 44–91% of the total capsaicinoids content. Total capsaicinoids ranged from 1.81 µg g−1 fw to 193.71 µg g−1 fw, with ‘Baklouti’ and ‘Jerid’ identified as the most pungent landraces. Total carotenoids ranged from 45.94 µg g−1 fw to 174.52 µg g−1 fw, with ‘Semmane’ and ‘Jerid’ exhibiting the highest levels. Considerable variation was observed in β-carotene content, spanning from 3% to 24% of the total carotenoids. α-Tocopherol content ranged from 19.03 µg g−1 fw in ‘Kairouan’ to 30.93 µg g−1 fw in ‘Beldi’, exerting a notable influence on the overall tocopherol content. Conversely, the β- and γ-tocopherol isomers were detected at very low concentrations. The total vitamin C content ranged from 132 mg 100g−1 fw in ‘Mahdia’ to 200 mg 100 g−1 fw in ‘Nabeul’, indicating relatively low genetic variability. However, large variability was detected in total phenolics content, ranging from 168.58 mg GAE kg−1 fw in ‘Beldi’ to 302.98 mg GAE kg−1 fw in ‘Cayenne’. Landraces such as ‘Dhirat’, ‘Nabeul’, ‘Semmane’, ‘Kairouan’, ‘Cayenne’, and ‘Mahdia’ appear suitable for both fresh consumption and processing, owing to their favorable average fruit weight, soluble solids content, and bioactive content. Among the pepper landraces tested, ‘Cayenne’ achieved the highest value of radical scavenging activity in both hydrophilic and lipophilic fractions (RSAHF and RSALF), with variations ranging from 59% to 120% for RSAHF and from 4% to 63% for RSALF.

Currently, they are recognized as a viable alternative to traditional remedies used to address certain ailments. However, the low yields of bioactive compounds obtained propitiate the use of more effective extraction techniques such as ultrasound-assisted extraction (UAE) in combination with statistical models such as Taguchi to maximize the yields of bioactive compounds. The objective of the research was to determine the optimal conditions for maximizing the yields of purified polyphenolic compounds from F. cernua and J. dioica using the Taguchi statistical model. In addition, we evaluated the total flavonoid content, antioxidant activity (ABTS•+, FRAP, and OH• hydroxyl radical inhibition), and the in vitro evaluation of α-amylase inhibition and ex vivo hemolysis inhibition. Furthermore, a functional group analysis was conducted using FTIR. The optimization process revealed that the maximum yields of bioactive compounds for F. cernua and J. dioica were achieved with a particle size of 0.25 mm and 0.30 mm, temperatures of 60 °C for both, a water–ethanol concentration of 50% for both, and extraction times of 30 min and 5 min, respectively. The matrix bioactive compounds obtained contain flavonoid-type phenolic compounds, which exhibit properties such as inhibiting free radicals and acting as reducing agents; inhibiting α-amylase activity, which is involved in carbohydrate metabolism; and protecting red blood cells from damage by reactive oxygen species. Finally, the FTIR analysis allowed for the identification of functional groups associated with the polyphenolic compounds (O–H, C–H, C–C, C=O). These results suggest that both non-timber forest species are a rich source of bioactive compounds with potential for application in the agri-food and pharmaceutical industries However, it is necessary to carry out compound identification as well as toxicity analyses to guarantee the safety of these bioactive compounds.","PeriodicalId":507445,"journal":{"name":"Horticulturae","volume":" 71","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Y.C. Dai & V. Papp is an important traditional Chinese medicine with diverse pharmacological properties. This study utilized a combination of PacBio Long-Read Sequencing, Illumina Short-Read Sequencing, and Hi-C Sequencing to generate a high-quality chromosome-level genome assembly of a W. hoelen strain Minling A5. There were 112 contigs in the genome, with 62.95 Mb in total length and 4.21 Mb in length for the contig N50. The average GC content was 51.89%. Based on Hi-C data, we corrected the CCS data and scaffolded them into 14 pseudo-chromosomes. The genome contained 44.37% repetitive sequences and 12,670 protein-coding genes, 86.53% (10,963) of which could be functionally annotated in at least one of the KOG, GO, Pfam, Swissprot, TrEMBL, NR, and KEGG databases. In addition, 240 transfer RNAs, 97 ribosomal RNAs, and 103 other non-coding RNAs were identified in the W. hoelen genome. A total of 755 pseudogenes were also identified, with an average length of 2665.51 bp. Further, there were 398, 100, 2837, 519, and 2068 genes annotated by CAZymes, TCDB, PHI, P450, and DFVF databases, respectively. One notable attribute of W. hoelen is its capacity to thrive in a substrate of fresh pine sawdust. Through an analysis of the growth on various pure wood sawdust culture media, we found that the growth of W. hoelen and Sparassis latifolia on pine sawdust was similar to that on broad-leaved wood sawdust, while the growth of Pleurotus ostreatus, P. eryngii, and Cyclocybe aegerita was slower than that on broad-leaved wood sawdust. By the functional annotation analysis of orthogroups in these five mushroom-forming fungi, it was determined that 645 orthogroups were specifically common in W. hoelen and S. latifolia. The genes in these specific orthogroups were significantly enriched in 12 pathways, including steroid biosynthesis, biosynthesis of antibiotics, and tyrosine metabolism. The high-quality genome and comparative genome analysis results significantly contribute to advancing our foundational knowledge of W. hoelen biology, while also offering valuable insights for the development of innovative biotechnological approaches aimed at enhancing the efficient and sustainable utilization of Pinus.","PeriodicalId":507445,"journal":{"name":"Horticulturae","volume":"88 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141683859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, sewage sludge from two wastewater treatment plants (WWTPs) subjected to two disinfection and stabilization treatments [40% (mass/mass), calcium oxide, and calcium hydroxide] and their respective untreated sewage sludge were used. Three control treatments were also added: conventional farmyard manure (FYM), a nitrogen (N) mineral fertilizer (ammonium nitrate 34.5% N) applied at a rate of 50 kg N ha−1 (N50) (the same rate of all organic amendments), and an unfertilized control (N0), totaling nine treatments. Lettuce (Lactuca sativa L.) was cultivated in pots for two growing cycles. The dry matter yield (DMY) was higher in the N50 treatment (13.5 and 10.6 g plant−1 in the first and second growing cycles, respectively), followed by sewage sludge (10.8 to 12.4 and 8.4 to 8.7 g plant−1), FYM (8.5 and 7.2 g plant−1), and the control (7.7 and 6.0 g plant−1). The DMY was related to the N provided by the different treatments, assessed by the N and nitrate concentrations in tissues, N uptake, and apparent N recovery (ANR). Sewage sludge, due to its high N concentration and low carbon (C)/N ratio, mineralized rapidly, providing a significant amount of N to plants, as well as other nutrients, such as phosphorus (P) and boron (B). FYM, with a higher C/N ratio, provided less N to plants, also due to the short duration of the lettuce growing cycle. Alkalized sewage sludge increased soil pH and calcium (Ca) availability for plants. Fertilizer treatments minimally influenced cationic micronutrients. Heavy metals in the initial sewage sludge were below the threshold values established in international legislation, and the levels in soil and lettuce tissues were generally not higher than those in other treatments. Both of the sewage sludges used in this study showed high fertilizing value and very reactive behavior, making nutrients available much more quickly than FYM.
