In this work, we elaborate on the qualities of the murta (<jats:italic>Ugni molinae</jats:italic> Turcz) fruit such as the colour, the volatile organic compounds (VOCs) present, its antioxidant capacity and the phenolic compound content (including those of flavonols and anthocyanins) with respect to the different ripening stages. Four stages were established based on the skin colour parameters, which were consistent with the changes in the weight and size of the murta fruits. In addition, the total phenolic and flavonols content showed a decrease during fruit ripening, in contrast with the total anthocyanins content that increased at the final stages of ripening. Additionally, the antioxidant capacity was evaluated via two approaches: ferric reducing antioxidant power and 1,1-diphenyl-2-picrylhydrazyl discolouration assay; higher levels of antioxidants at the final stages were consistently observed. Furthermore, the VOCs profile showed terpenoids to be the main compounds, with the highest relative abundances in fully ripe fruits. These results allow us to propose a classification of the different ripening stages of the murta fruits. This would enable us to have better knowledge of this interesting fruit, which possesses highly healthy nutraceutical compounds.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"17 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140629678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to relevant studies, mainstream research direction is aimed at utilizing MF treatment to improve the economic traits of horticultural and agricultural crops. MF has positive effects, for example, on seed germination, seedling growth, crop yield and quality and plant tolerance to stress. In recent years, more and more researchers have focused their work on using seed MF or magnetised water (MW) irrigation treatment to improve plant tolerance to salt or heavy metal stresses, to achieve the purpose of soil restoration by plant heavy metal accumulation. In this review, the most commonly utilised MF or MW treatment methods have been described in detail, and the effects of MF treatment on horticultural and agricultural crops have been presented. Furthermore, new prospects for MF treatment and the associated molecular basis have been presented. Since different species or cultivars have different optimal dose requirements for MF treatment, it is still a challenge presently to promote MF treatment use in commercial applications. For successful implementation of MF treatments, it is essential to conduct a large number of screening experiments and more in-depth research on the effects of MF on cultivated plants.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"260 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140017997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under salt stress, 2 mM Gln application reduced the mean germination time (MGT) (4.51 days), increased the coefficient of velocity of germination (CVG) (75.85), germination index (GI) (1.46) and germination percentage (GP) (82%), indicating that it was the best application for germination under stress. Gln promoted the development of aboveground plant organs. 3 mM Gln increased the number of leaves from 5.3 to 13.7 and 4.3 to 6.6 under unstress and stress conditions, respectively. Under salt stress, Gln increased photosynthetic pigments and genomic template stability (GTS) (80%). At 2 mM Gln, total chlorophyll and carotenoid content increased from 1.59 mg · g<jats:sup>-1</jats:sup> TA to 2.23 mg · g<jats:sup>-1</jats:sup> TA and from 0.28 mg · g<jats:sup>-1</jats:sup> TA to 0.37 mg · g<jats:sup>-1</jats:sup> TA, respectively. The effect on gene expression levels varied with the concentration. The application of 2 mM Gln, which enhanced germination and vegetative parameters under stress, caused a raise in CuZn-SOD gene expression and a 43% decrease in the transcriptional expression of the HSP-21 gene as an indicator of the functionality of the repair mechanism. The improved growth of Gln-treated plants under stress suggests that Gln is involved in bridging the energy deficit of the plant by acting as an alternative fuel for metabolic activities under stress.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"55 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139945428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So, we investigated the effect of exogenous MT at 0 μM, 50 μM, 100 μM and 150 μM on lettuce plants grown under salinity stress (0 mM NaCl, 50 mM NaCl and 100 mM NaCl) with respect to vegetative growth, photosynthetic pigments, relative water content (RWC), electrolyte leakage (EL), malondialdehyde (MDA), H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>, O<jats:sub>2</jats:sub> <jats:sup>•-</jats:sup> and antioxidants enzymes.

The present study was conducted with an aim to define and describe phenological stages of common fig cultivar ‘Diana’ in arid regions according to the Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH)-scale using two-digit numerical system. The BBCH scale markedly explains various developmental stages of crops. Seven principal growth stages, viz. bud development (0), leaf development (1), shoot development (3), inflorescence development (5), flower development (6), syconium (fig receptacle) development (7) and fruit maturation (8), and 25 secondary growth stages of fig have been described. The sequential progression of principal growth stages of fig indicated temporal variation in growth pattern as well as overlapping of secondary growth stages. Phenological description will act as a pragmatic approach to define growth stages in order to facilitate timely agronomic practices such as canopy management, nutrient management and irrigation scheduling, pest and disease management. Since fig is considered one of the important minor fruits of India, a detailed phenological description will be instrumental in enhancing its potential in arid and semi-arid regions.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"9 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139656546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted over six generations for 4 consecutive years, using the single seed descent method. The last phase (VI) consisted of growing plants of the F5 generation for selection. Qualitative (LD) and quantitative (QD) descriptors were considered and the ideal genotypes were defined. The statistical analyses consisted of estimating variance components and genetic parameters and predicting genetic values, using REML/BLUP for QD, except for cycle to flowering (CF) and cycle to maturation (CM), which were analysed qualitatively. Therefore, CF and CM were analysed through frequency distribution of continuous variables within class intervals. Descriptive statistics were used to evaluate LD. The results showed that residual values exceeded genetic values, resulting in low heritability for QD, and therefore, they were not considered for PIL selection. Regarding LD, genetic variability was found among the population genotypes for all evaluated descriptors. The selection based on ideal genotypes enabled the selection of 82 PIL with LD of high ornamental value, which differ from the materials already available on the market. The selected genotypes will be used for developing future generations until allele fixation, focussed on subsequent selection of candidate lines for new ornamental pepper cultivars.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"8 7","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138943950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We observed plants’ response to osmotic stress, the decrease in growth and microshoot weight. A change in the expression of the investigated genes was evident under the suboptimal concentration of sucrose. The addition of PEG to the medium caused a decrease in microshoot weight and gene expression. Blue + red lights of the LED lighting system significantly affected microshoot growth <jats:italic>in vitro</jats:italic>. Red and blue + red + UV lights slightly reduced microshoot weight and caused a reddish colour of petioles, which indicate increased anthocyanin synthesis. Moreover, most of the studied genes’ expression tended to increase when shoots were exposed to blue, blue + red and blue + red + UV lights. A temperature of 15°C (vs 22°C) significantly reduced the mean fresh weight of microshoots while increasing <jats:italic>CHI</jats:italic> and <jats:italic>CHS</jats:italic> gene expression and decreasing <jats:italic>WD40</jats:italic> gene expression. Exposure to a higher temperature (30°C) induced the vitrification of microshoots, although the fresh weight did not differ from that of the control. Gene expression also depended on the duration of exposure. In the case of <jats:italic>CHS</jats:italic>, gene expression remained the same or increased after exposure for 1 week and then decreased after exposure for 4 weeks.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"71 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138682610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
