Soybean is also capable of accumulating selenium (Se). To study the effects of Se biofortification on the nutrient of this crop, soybean sprouts were treated with different concentrations of selenium nanoparticles (SeNPs) or selenite (i.e., 10 μM, 20 μM, 40 μM, 80 μM and 100 μM) in a hydroponic experiment. Results showed that SeNPs and selenite remarkably increased the total Se concentration in soybean sprouts. Five Se speciations, namely, selenocystine, selenomethionine, methyl selenocysteine, selenite and selenate were detected in soybean sprouts, but selenomethionine was found to be the dominant Se speciation. SeNPs and selenite increased the contents of chlorophyll, carotenoid, soluble sugar, soluble protein, vitamin C and isoflavones in soybean sprouts. SeNPs treatments led to less malondialdehyde content compared with selenite. SeNPs and selenite both enhanced the glutathione content. The modest dosage of exogenous Se stimulated the catalase activity, whereas the large amount reduced it. The peroxidase and ascorbate peroxidase activities were stimulated by SeNPs and selenite. SeNPs posed no significant influence on the superoxide dismutase activity. This study suggests that SeNPs are a good exogenous Se source for the production of Se-rich soybean sprouts.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"34 1","pages":"223 - 234"},"PeriodicalIF":2.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47312832","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 field observations showed that the sprouting index, which represents the time and speed of bud flush, was significantly higher in most of the WSL treatments than in the control (CK, p < 0.01). The total content of catechin in the harvested leaves of 3 WSL treatments was 11.51%–18.94% higher than that of the CK, but the content of anthocyanin of 4 WSL treatments unexpectedly decreased by 6.77%–11.69% (p < 0.05). The differences in yield, free amino acids and caffeine contents between the WSL treatments and CK were not significant. We concluded that the WSL treatments during the early spring night had positive impacts on the growth and some quality components of tea plants.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"34 1","pages":"263 - 269"},"PeriodicalIF":2.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47522623","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}

Increasing environmental sensitivity at the global level has tremendously enhanced the demand for such methods. Azadirachta indica is a well-known medicinal tree. As glycerol has emerged as a green and safe extraction solvent for bioactive phytochemicals, this study aimed to investigate the efficacy of a glycerol–water solvent system to extract bioactive compounds from A. indica leaves. Modelling and optimisation were carried out by using response surface methodology (RSM) as per the Box–Behnken design with three variables, namely, solvent concentration, time and temperature. The responses were total phenolic content (TPC), total flavonoid content (TFC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and metal chelating activity (MCA). The optimum conditions found by numerical optimisation were a solvent concentration of 69.713%, a time period of 38.328 min and a temperature of 32.114 °C with the predicted values of TPC, TFC, %DPPH and %MCA as 5.27 mg gallic acid equivalents · g−1 DW (dry weight), 9.869 mg rutin equivalents · g−1 DW, 73.8% and 54.366%, respectively. The validation experiments showed almost the same results for each response with very low% errors (5.431–7.661). Increasing glycerol concentration in the extracting medium favoured the extraction of TPC, TFC and antioxidant phytochemicals, but for MCA, the trend was the opposite. In conclusion, 70% aqueous glycerol is an effective medium for the extraction of polyphenolic and antioxidant phytochemicals from A. indica leaves. Extraction models suggested by RSM have high prospects to be used on a large industrial scale.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"34 1","pages":"249 - 262"},"PeriodicalIF":2.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49069920","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}

Thus, the current study aimed to evaluate the effectiveness of different sunblocks to alleviate the abiotic stress of “Palmer” mango trees grown in a semiarid environment. The experimental design consisted of randomised blocks with six treatments, four repetitions and three plants per plot. The treatments consisted of different strategies of sunblocks as follows: (T1) control (no sunblock); (T2) calcium carbonate (50 g · L−1); (T3) sunblock (5 mL · L−1); (T4) sunblock (5 mL · L−1) + calcium carbonate (50 g · L−1); (T5) sunblock (5 mL · L−1) + sunblock silicon concentrated (20 mL · L−1) and (T6) sunblock (20 mL · L−1). The results indicate a clear action of sunblock in attenuating the abiotic stress of mango, with a persistent effect with time elapsing, considering the evaluated interval. The sunblock clearly promotes a differentiated leaf coverage pattern, protecting the photosynthetic apparatus and increasing its performance and consequently improving the production of plant reserves. The use of calcium carbonate individually promotes a very short protective effect, without positive reflexes after a few days of application. Mango fruit yield is affected by the sunblock with an increase of 4.2 t · ha−1 from the treatment with sunblock (20 mL · L−1) in relation to the control treatment.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"34 1","pages":"211 - 221"},"PeriodicalIF":2.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45493709","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}

Phenolic acids, which are one of the main useful compounds in dandelion, constitute one of the important groups of therapeutically significant bioactive compounds in traditional Chinese medicine. To carry out a relatively full evaluation of dandelion quality, it was found advisable to use multiple indices to avoid conflict with the single evaluation index stipulated by China Pharmacopoeia. Thus, a quality evaluation method was created based on traditional Chinese medicinal theory and relevant statistics on phenolic acids. Firstly, four main kinds of phenolic acids – caftaric acid, chlorogenic acid, caffeic acid and cichoric acid – were chosen as the main indices for quality evaluation through the optimisation of high performance liquid chromatography detection conditions and fingerprint comparison analysis; then, the content of each component was divided into five levels based on the descriptive statistics of 578 dandelion samples and references; finally, the equal weight average method was used to convert content levels of the four components into a comprehensive quality index, which served as the means for dandelion quality to be identified and segregated into grades, as follows: Grade 1 (super high, probability of 0.8%), Grade 2 (high, 18.72%), Grade 3 (medium, 37.28%), Grade 4 (qualified, 32%) and Grade 5 (low, 11.2%).

Heavy metals, pesticide residues, mineral elements, and biological efficiency were measured. Heavy metals were more commonly detected in the 73 apple-wood samples, but serious pollution was only an isolated phenomenon. No Pb was detected in P. ostreatus and L. edodes. The contents of Hg, As, Cd, and Cr were at safe levels. The contents of Ni were equivalent to those of wild mushrooms. Most notably, chlorpyrifos was detected in all the apple-wood tested. However, chlorpyrifos was only detected in L. edodes cultivated with apple sawdust. No other pesticide residues were detected in the other mushroom samples. The biological efficiency of P. ostreatus cultivated by apple sawdust was 89%, which was 80% of the control. The biological efficiency of L. edodes cultivated with apple sawdust was 81%, which did not differ significantly from the control. Apple-wood can replace wild oak as the material for L. edodes cultivation, but producers should ensure that the raw materials are safe. The main materials chosen to cultivate P. ostreatus should balance the two factors of raw material price and biological efficiency.","PeriodicalId":12277,"journal":{"name":"Folia Horticulturae","volume":"34 1","pages":"173 - 185"},"PeriodicalIF":2.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48006186","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}

Contrarily, destructive methods puncture the fruit and thus only a subsample, selected to represent all fruit, can be tested. In addition, different operators can generate quite different values for the same fruit using a hand-held penetrometer. Hass avocado from two commercial orchards was collected, and fruit firmness was measured at harvest, during two storage conditions controlled atmosphere (CA) and regular air (RA), during shelf-life and at the ready-to-eat stage using both destructive (Fruit Pressure Tester, mod.

Then, the mathematical relationship between these two devices was assessed using Spearman Correlation coefficient (rho) and p-values adjusted by Benjamini-Hochberg and Bonferroni procedures. Thus, 3,200 fruits were evaluated during two harvests and two subsequent seasons. A moderate and positive association between destructive and non-destructive devices was found (rho coefficient ranging from 0.41 to 0.51). The variance explained by the regression models ranged from 0.53 to 0.63; all of them were significant with good accuracies (i.e., 0.79; 0.78; 0.73; 0.76).
