All treatments were foliar applied twice (December 15–January 15) in both seasons. Yield and fruit quality were studied. Treatments significantly improved yield, physical fruit and fruit chemical characteristics, moisture content, chlorophyll a, b and total chlorophyll by most tested treatments in both seasons than the control (water only). Yeast spray treatments significantly decreased juice content vitamin C (mg/100 g), while KNO3 spray treatments increased juice content vitamin C in both seasons. It can be concluded that foliar application with KNO3 at 2% recorded the best treatment to obtain the highest yield, fruit weight, flesh weight, fruit volume, fruit length and fruit diameter, while yeast extract at 2% treatment gave the highest TSS% and total sugar contents in this study.","PeriodicalId":7230,"journal":{"name":"Acta Scientiarum Polonorum Hortorum Cultus","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43560179","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 goal of the present study was to investigate the chemical compounds, antioxidant, and antimicrobial properties of essential oil of Juniperus excelsa M. Bieb., a species of juniper with a large spread area in Turkey. Essential oils were extracted by the hydro-distillation method. The components of the hydro distilled oil samples were analyzed by gas chromatography-mass spectrometry (GC-MS). In the study, the essential oil was evaluated for its antibacterial activity against six bacterial strains consisting of two Gram (+) and four Gram (–) by the agar disc diffusion method. Additionally, the antioxidant properties of the oil were determined by TEAC/ABTS+ free radical scavenging assay. As a result, there were 27 compounds in the essential oil of J. excelsa. Of the 27 essential oil components identified, α-pinene (40.59%), α-cedrol (18.15%), β-myrcene (4.53%), and limonene (3.84%) were determined as the main components in total 91.54% of the essential oil. As a result, it was observed that the examined juniper essential oil showed a weak but effective antibacterial activity against all bacterial strains compared to the control agents, and also, the examined oil had low but valuable antioxidant activity.","PeriodicalId":7230,"journal":{"name":"Acta Scientiarum Polonorum Hortorum Cultus","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44001273","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}

A 0–4 disease rating scale was used to analyze the genotypes, and the genotypes were categorized as resistant, moderately resistant and susceptible based on disease incidence and disease severity scores. The findings revealed that there were significant (p < 0.01) differences in disease incidence and severity among genotypes. The study demonstrated that one of the 25 tested C. baccatum genotypes (KTB-11) found to be resistant, and three genotypes (KTB-29, KTB-34, KTB-57 and KTB-72) were rated as moderately resistant to CMV. However, it was determined that all tested C. frutescens and C. annuum genotypes were susceptible to CMV.

The goal of this study was to determine the efficacy of foliar SA treatments (0.25, 0.50, or 1.00 mM) in reducing salt stress in lettuce exposed to 100 mM NaCl. Salt-stressed plants given a foliar application of SA showed alleviation of the negative effects of salinity, resulting in higher growth performance (increases of 6%–198%). The positive impacts of SA were especially noticeable as an increase in the content of photosynthetic pigments, such as total chlorophyll (31–72%) and total carotenoids (49–141%). Application of SA also helped to reduce membrane damage, as seen by significantly lower levels of MDA (31–70%) in the leaves of salt-stressed lettuce plants. Moreover, the use of SA enhanced overall flavonoid and phenolic content, as well as nutrient absorption. SA treatment also increased the activities of antioxidant enzymes, such as ascorbate peroxidase, catalase, glutathione reductase, and superoxide dismutase, resulting in a considerable reduction in salt-induced oxidative damage. The most efficient SA application concentration was 0.50 mM. Overall, the use of SA as a foliar spray could be recommended as a long-term strategy for improving the defense systems of salt-stressed lettuce.","PeriodicalId":7230,"journal":{"name":"Acta Scientiarum Polonorum Hortorum Cultus","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49669162","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 experiment was carried out on three cultivars of highbush blueberry: ‘Bluecrop’, ‘Brigitta blue’ and ‘Darrow’. Pot plants were treated two times with dikegulac (0.1%) or/and Asahi SL (0.2%) foliar sprays in the late spring. The reaction of blueberry clones to the tested chemicals was different. Dikegulac-treated plants developed significantly more shoots making them a good and efficient source of cuttings when using the traditional propagation. Dikegulac limited the shoot elongation of two studied cultivars (‘Bluecrop’, ‘Darrow’). It also reduced the size of leaf blades but generally did not change the fluorescence and the relative content of chlorophyll. The influence of dikegulac in the applied dose was much stronger than the impact of nitrophenolates.

Flaming (90 kg propane∙ha–1) was applied immediately before thyme emergence or 6 days later, and glufosinate-ammonium (450 g∙ha–1) was applied on the same date as the first flaming. Emergence of thyme began 15–18 days after sowing, was very uneven and in some years it was extended up to 4 weeks. Thyme seedlings were very fine and their initial growth was very slow, which made them highly sensitive to the competition of weeds. The growth rate of thyme increased over time, reaching its greatest value in the last ten days prior to harvest, when the plants gained their average height, depending on the year, from 18.3 to 22.4 cm and developed from 17 to 21 first and second order branches. Weeds started to emerge 8–11 days after thyme was sown and about 3 weeks later their number in the control plots varied depending on the year from 175 to 541 pcs.∙m–2. All methods were very effective in controlling weeds immediately after treatment, but had no soil residual activity and soon new weeds emerged. Four weeks later, the most effective method was spraying with glufosinate-ammonium, which, depending on the year, reduced both the number and fresh weight of weeds by 43 to 85%. Flaming applied at the first or second dates controlled 33–59% and 37–68% of weeds, respectively. After first weeding, the differences between compared treatments disappeared. Essential oil content in the grated herb obtained from the control plants ranged from 2.5 to 3.4%.
