The total content of phenolic compounds in the flesh with skin was lowest in ‘Mount Everest’ (3603.57 mg · kg−1 f.w.), which is derived from R. pendulina, and highest in ‘Splendens’ (68789.39 mg · g−1 f.w.), which is derived from R. gallica. In seeds, the phenolic compound content was lower, as expected, ranging from 757.02 mg · kg−1 f.w. (‘Mount Everest’) to 6823.21 mg · kg−1 f.w. (‘Single Cherry’). It can be concluded that the cultivars differ significantly from each other due to the content of different bioactive compounds. Based on the obtained results, we cannot determine to which basic rose plant the cultivar belongs based only on the content of one analysed compound. The contents were very different because only one parent plant is known for a given cultivar and breeding programmes in roses were very narrowly focussed on specific targets.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141266200","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}

This study investigated the effectiveness of using coatings based on natural polymers to prolong the shelf life of fruits and protect their tissues from damage. Specifically, the researchers examined the impact of putrescine (PUT), chitosan (CTS) and chitosan–putrescine nano-composites (CTS-PUT NPs) on preserving the quality and reducing decay in strawberry. Strawberries were treated with either 1 mM or 2 mM of PUT, 0.1% CTS, 0.1% CTS-PUT NPs or distilled water at a temperature of 20°C for 5 min and then stored at 4°C for 12 days. At the end of the storage period, the lowest decay percentage was related to the treatments of CTS-PUT NPs and CTS, and the highest was observed in the control. The results showed that all coating treatments effectively prevented the excessive loss of ascorbic acid, fruit firmness, total soluble solids (TSS), and acidity (TA) compared to control at the end of the storage period. Additionally, strawberries treated with CTS-PUT NPs and CTS demonstrated the highest levels of total anthocyanin and total flavonoid. Antioxidant enzyme activities containing CAT and SOD were preserved at higher levels in treated strawberries than in the control during cold storage. These results confirm that the application of CTS and CTS-PUT NPs can effectively preserve fruit quality and prolong the longevity of strawberries during cold storage by enhancing their antioxidant capacity and scavenging free radicals.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141266067","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}

One of the most important aspects of the evaluation of cultivars is therefore the determination of their frost tolerance. In this paper, the frost hardiness of flower buds of 16 apricot cultivars was investigated in three dormancy periods, applying a standardised artificial freezing test protocol and determining LT<jats:sub>50</jats:sub> values. The results showed that both the genotypes and the yearly climatic conditions had a significant effect on frost tolerance. A genotype generally determines the potential maximum of its frost tolerance (‘Sweet Red’ and ‘Primaya’ were very sensitive to frost every year, while ‘Harlayne’ and ‘Rózskajszi C.1406’ could be considered as frost hardy). Flower buds can reach different levels of frost resistance each year depending on the temperature conditions during the hardening and dehardening periods. From the point of view of yield security, it is essential when planning an orchard, to take into account and harmonise the frost hardiness of the cultivars selected and the growing site conditions. Therefore, it is very important to have adequate information about the frost hardiness of different apricot cultivars, which should be included in cultivar descriptions. This paper is intended to contribute to this goal.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140839006","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}

Improving the heat tolerance is imperative for the strawberry plants to remain productive under high temperature conditions. The present work aimed to study the effect of heat acclimation on the thermotolerance of strawberry plants subjected to severe heat stress. Tissue cultured Fragaria ‘Taoyuan No. 1’ plantlets were subjected to four heat-acclimation treatments with gradual increase of temperatures from 30°C to 42°C for 1.25 hr to 10 hr before exposing them to the lethal temperature of 48°C for 4 hr. Survival, new leaf emergence and root growth, electrolyte leakage, chlorophyll and proline contents, as well as antioxidant enzyme activities were compared between the control, acclimated and non-acclimated plantlets. Results indicated that heat acclimation was required for the strawberry plantlets to survive under lethal temperature conditions. The acclimated plantlets registered a lower degree of electrolyte leakage and chlorophyll degradation, and a higher proline content compared to the non-acclimated plantlets. The activities of the antioxidant enzymes increased with the elevation of acclimation temperature and peaked at 42°C except for ascorbate peroxidase (APX) whose activity peaked at 39°C. Higher activities of superoxide dismutase (SOD), APX, glutathione reductase (GR), catalase (CAT) and peroxidase (POD) were observed in the acclimated plantlets compared to the non-acclimated plantlets. This study demonstrates that heat acclimation improved the thermotolerance of in vitro strawberry plantlets by reducing electrolyte leakage and chlorophyll degradation, as well as by enhancing proline content and antioxidant enzyme activities under severe heat stress.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140663850","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}

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.

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":null,"pages":null},"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":null,"pages":null},"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}
