Opis:
The efficacy of three types of mineral spray oil (MSO), and Abamectin plus MSO to control the citrus leafminer Phyllocnistis citrella Stainton were compared with the conventional broad spectrum pesticides, Confidor, and Dursban, in two citrus orchards in northern Iran. Differences were found among the various concentrations of MSO in the number of mines and live larva per leaf, sampled 5 days after the application of 3 sprays at an interval of 5 days. Mineral spray oil applied at a rate of ≥ 0.65% in water, showed no significant differences when compared with Confidor, and Dursban. Abamectin plus MSO at a rate of 0.02% plus 0.50% in water respectively, provided the highest level of control and reduced the population of larva up to 85%. Generally, a concentration of ≥ 0.65% MSO in water caused a significant damage reduction. However, by reducing the MSO concentration, the rate of control was decreased. In another field experiment conducted in mature citrus orchards, the effect of two pest management types (applying just MSO vs. usage of synthetic pesticides) on the activity of P. citrella, was evaluated. The comparison results indicated that there is more P. citrella damage in orchards under pressure of synthetic pesticides than in orchards in which the synthetic pesticides were eliminated for years.

Opis:
In this study, cassava starch cross-linked using sodium trimetaphosphate was used as basic material to prepare the preservation coating agent. The addition levels of β-cyclodextrin, phytic acid and glycerol were optimized by response surface methodology with the comprehensive index of oil permeability (OP) and the water vapor permeability (WVP) of starch-based coating. The optimal formulation of the cross-linked cassava starch-based coating was as follows: 3 g/100 g cassava cross-linked starch, 0.7 g/100 g β-cyclodextrin, 0.5 g/100 g phytic acid, and 0.5 g/100 g glycerol. The preservation coating solution prepared by the optimized formula was applied to the postharvest storage of ‘Shatangju’ mandarins. The coating treatment effectively slowed down the decline of firmness during storage for 20 days at room temperature, reduced the decay rate (by 111.73%) and weight loss rate (by 43.40%), and inhibited the postharvest respiration (by 42.06%) of fruit. The soluble solid content, titratable acidity and ascorbic acid content of the coated ‘Shatangju’ mandarins were higher 1.32 times, 1.55 times, and 1.52 times, respectively, compared with the corresponding indexes of the control fruits. All these results indicate that the coating treatment could effectively reduce the loss of nutrients, delay the wilting and decay, prolong the shelf life after harvest, and improve the commercial value of ‘Shatangju’ mandarins.

Opis:
Nucellar embryony is the major obstacle in getting hybrid seedlings in interspecific crosses in citrus. Hence, the present study was conducted to standardize embryo age, culture media for maximizing germination, and subsequent identification of simple sequence repeat (SSR) markers to differentiate the hybrids. A factorial experiment was conducted with three embryo ages – 80–90, 110–120, and 130–140 days after pollination (DAP). The germination of the rescued immature embryos of acid lime × lemon crosses was initiated on three different growing media. The fruits harvested at 130–140 and 80–90 DAP had a higher number of functional seeds (90%). Older embryos (130–140 DAP) and middle-aged embryos (110–120 DAP) germinated in 100% on Murashige and Skoog (MS) medium supplemented with 500 mg·l -1 malt extract, 1.5 mg·l-1 gibberellic acid (GA3), and 0.02 mg·l-1 naphthalene acetic acid (NAA). MS medium supplemented with 500 mg·l-1 malt extract proved better for the germination of embryos taken at 80–90 DAP. Plantlet survival was the highest in younger embryos (80–90 DAP) cultured on MS basal medium (84.21%) and the lowest in older embryos cultured on MS medium supplemented with 500 mg·l-1 malt extract plus 1.5 mg·l-1 GA3 and 0.02 mg·l-1 NAA. The seedlings obtained from the culture 80–90 DAP had the highest root length (4.9 mm) and shoot length (5.3 mm) at 60 days after inoculation (DAI) on the above medium. SSR marker analysis revealed that CCSM-4 and CAC-33 markers expressed polymorphism between female and male parents, proving their ability to identify the hybrids of ‘Kagzi’ acid lime × ‘Konkan Seedless’ lemon.

Opis:
The black citrus aphid, Toxoptera aurantii Boyer de Fonscolombe (Hemiptera: Aphididae), an important pest of citrus species, feeds by sucking sap from plant leaves. It causes some leaf distortion and malformation of growing leaves and shoot tips. In this study, the eff ects of the botanical insecticide, palizin on T. aurantii and its parasitoid, Aphidius colemani Viereck (Hymenoptera: Brachonidae) were compared with the chemical insecticide, imidacloprid. Th e compounds were evaluated at maximum recommended fi eld concentrations: palizin 2,000 ppm, imidacloprid 500 ppm, water (as control) on adult aphids. Spraying was done with a 100-l engine Honda sprayer (GX120T1, 160T1, 200T) until run-off . Th e number of dead aphids was recorded 24, 48 and 72 hours aft er treatment. According to the results, statistically signifi cant diff erences were found between treatments (p ≤ 0.05). Twenty-four hours aft er treatment, imidacloprid was more eff ective than palizin in reducing the T. aurantii population. Palizin showed high effi ciency (95% mortality) 72 hours aft er treatment. However, at that time, there was no statistically signifi cant diff erence between the mean mortality percentages of imidacloprid and palizin. This shows that botanical insecticide, palizin can eff ectively control T. aurantii. Also, palizin caused low mortality (10.86%) on A. colemani while imidacloprid was more toxic (31.1% mortality). The results of the present study indicated that palizin can be used instead of chemical insecticide, imidacloprid in control programs of T. aurantii.

Opis:
Introduction: Due to its low cost and easy availability on the market, the petitgrain oil is commonly used in food, cosmetics, and aromatherapy. Objective: The examination of chemical composition and antibacterial activity of commercial petitgrain oil. Methods: Identification of chemical components of the petitgrain oil was performed by gas chromatography (GC). The minimum inhibitory concentrations (MIC) and minimum bactericidal/fungicidal concentrations (MBC/MFC) were determined using macrodilution method for the reference strains of bacteria and fungi. Results: Twenty components were identified. The petitgrain oil contained mostly oxygenated monoterpene hydrocarbons (98.01%), and the main components included linalyl acetate (48.06%) and linalool (26.88%). The MIC/MBC of the petitgrain oil for bacteria was in the range of 0.63–5.0/1.25–5.0 mg/ml and for fungi in the range of 1.25–40/5.0–80 mg/ml. Conclusion: The petitgrain oil had higher antibacterial activity than antifungal activity. Bacillus subtilis among the tested bacteria and Aspergillus niger and Penicillium expansum among the fungi were found to be highly inhibited by the petitgrain oil.

Opis:
Citrus bacterial canker, caused by Xanthomonas citri subsp. citri (Xcc), is a destructive disease. So far, the chemicals used to control this pathogen are either ineffective or harmful to the environment. To improve control of this disease, lime (Citrus aurantifolia) were treated with L-arginine, L-methionine, L-ornithine, and distilled water. Plants were inoculated with Xcc, 48 hours post treatment. Lesion diameters of inoculated leaves were evaluated four weeks after inoculation with a bacterial suspension. Changes in β-1,3-glucanase transcript levels and activity of antioxidant enzymes, catalase, peroxidase, and phenylalanine ammonia-lyase were investigated at 48 hours post treatment and 24, 48, and 72 hours post inoculation. Based on the results of phenotypic, antioxidant enzyme activity and a molecular study of the stressed plants, it was found that those plants treated with the amino acid methionine significantly increased the plant induced resistance as well as decreased the severity of disease by reducing necrotic lesion size.

Background. Use of plant extracts and phytochemicals with known antimicrobial properties may have great significance in therapeutic treatments. Objective. To assess the in vitro antimicrobial potential and also determine the minimum inhibitory concentration (MIC) of Citrus sinensis peel extracts with a view of searching a novel extract as a remedy for periodontal pathogens. Materials and Methods. Aqueous and ethanol (cold and hot) extracts prepared from peel of Citrus sinensis were screened for in vitro antimicrobial activity against Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Prevotella intermedia, using agar well diffusion method. The lowest concentration of every extract considered as the minimal inhibitory concentration (MIC) values were determined for both test organisms. Confidence level and level of significance were set at 95% and 5% respectively. Results. Prevotella intermedia and Porphyromonas gingivalis were resistant to aqueous extracts while Aggregatibacter actinomycetemcomitans was inhibited at very high cncentrations. Hot ethanolic extracts showed significantly higher zone of inhibition than cold ethanolic extract. Minimum inhibitory concentration of hot and cold ethanolic extracts of Citrus sinensis peel ranged between 12-15 mg/ml against all three periodontal pathogens. Conclusions. Both extracts were found sensitive and contain compounds with therapeutic potential. Nevertheless, clinical trials on the effect of these plants are essential before advocating large-scale therapy.

Proteases are one of the most important enzymes that have various physiological and industrial applications. This study was carried out to purify and partially characterize proteases from Citrus sinensis fruit peel. Three active fractions of the proteases (I, II and III) were obtained. The Vmax for proteases I, II, III and pooled fraction were 185.19, 192.31, 111.11 and 163.93 U/ml with Michaelis-Menten’s constant (Km) 1.01, 0.44, 0.67 and 0.37 mg/ml respectively. The enzymes were optimally active at 40-50 °C. However, they retained activity at 60-70 °C. Protease I was stable up to 60 °C while proteases II and III retained more than 80% activity in the range of 25-70 °C. The optimal pH of proteases II and III was 7 while protease I was optimally active at pH 8. The enzymes were stable at alkaline pH especially between 6 and 9 retaining more than 60% of its activity. The stability of these enzymes at high temperature and different pH may be an indication of its potential applications in food, chemical and laundry industries.

Opis:
Currently, agriculture has shifted to green production, in which the recycling of post-production by-products is a key issue. In the present work, by-products such as pomelos were studied to promote consumption and enhance the value of pomelo. From pomelo material, essential oils extracted from pomelo peels, pectin, and drying pomelo products have been diversifi ed. In the extraction process of essential oils, the hydrodistillation method was applied in conjunction with the response surface method to obtain the optimal conditions of infl uence factors. These essential oils were quantifi ed as well as determined for components by GC-MS. The pectin recognition process was done by immersion method in HCl acid (pH 2) and the drying process was made with a heat pump dryer under the effects of drying temperature, drying time and wind rate. The results of the essential oil products reached the highest (0.88 ±0.006 g) at the material size of 3 mm, the distillation time of 27 min, and the ratio of raw materials/solvents of 1/12 g/mL. The main components found in pomelo peeling essential oils included limonene (71.768%), γ-terponene (12,847%), α-Phellandrene (2.979%), β-myrcene (2.668%), 1R-α-pinene (2,656%), and β-pinene (1,191%). The pectin content was the highest under the temperature of 90 oC, extraction time of 60 min and ratio/solvent ratio of 1:32 g/mL. Under these extraction conditions, 48% of concentrated pectin content was obtained. Surveying conditions for drying white pomelo peels are capable of reversing: refunded drying pomelos are drying heat pumps in the following conditions: 50 oC drying temperature, the drying time of 90 min, and wind rate of 12 m/s. Product with hardness 309.862 N.

Opis:
Evaluating the ecological economic benefits of different ecological restoration patterns in abandoned mines is important in ecological restoration study. Taking the abandoned coal mine in Luoshi Township of Fengcheng county, Jiangxi province, as a case, 4 different ecological restoration patterns (grapefruit with grass vegetation – Pattern I, pine with grass vegetation – Pattern II, grapefruit – Pattern III, and bare slope – Pattern IV) have been conducted to study the runoff and sediment yield under natural rainfall conditions. The results showed that the ecological restoration patterns and rainfall intensity can significantly affect runoff and sediment yield which increased as rainfall intensity increased: Pattern IV > Pattern III > Pattern II > Pattern I. For the optimal ecological restoration with Pattern I, the average runoff and sediment reduction was 59.01 and 77.1%, respectively, in all rainfall intensities. Multivariate analysis of variance (MANOVA) showed that runoff and sediment were significantly affected by ecological restoration pattern and rainfall intensity (P < 0.05). Correlation analysis of runoff and sediment yields indicated that the reduction effect on sediment yield increased with the decrease of runoff, and the relationships between runoff and sediment at different ecological restoration patterns could be fitted with a linear function. Moreover, the vegetation configuration that combines fruit farming with grass can be not only beneficial to control soil and water conservation but produce considerable economic and ecological benefits.

Opis:
This research delves into the identification of opportunities for the consolidation of the lemon value chain in the department of Tolima, Colombia, through the associativity model called: Special Administrative Planning Region. This model is a land-use planning system, officially recognized in Article 325 of the Political Constitution of Colombia and in Law 114 of 2011, which functions as a planning tool at the regional level. Its main objective is to integrate a given region with other territorial entities at the departmental level. The study is framed within exploratory research that employs qualitative and quantitative methodologies for its development, in addition to using data collection instruments, in order to identify the main elements that define the possibilities of establishing a profitable and sustainable value chain in the citrus-lime sector in Tolima. The results show that the potential for competitive insertion of lemon in global value chains reaches likely international markets such as Russia, Germany, France, Poland, Canada and Saudi Arabia, and the support of different government institutions. However, it is necessary to overcome major threats and weaknesses that currently hinder this insertion.

Opis:
Historia uprawy roślin cytrusowych sięga czasów starożytnych, jednak to w dobie renesansu zyskały one szczególne znaczenie jako element sztuki ogrodowej. Wtedy też zaczęto wykorzystywać nie tylko ich użytkowy charakter, ale również wartości dekoracyjne i znaczenie symboliczne. Pierwsze udokumentowane wykorzystanie cytrusów do celów propagandowych miało miejsce w ogrodzie Medyceuszy w Castello nieopodal Florencji. W okresie tym owoce cytrusów utożsamiano z mitycznymi „złotymi jabłkami” Hesperyd, fakt ten wykorzystany został przez ród Medyceuszy w tworzeniu ogrodu o politycznym przesłaniu. Wspaniałą kolekcję roślin kubłowych, w tym cytrusów, posiadał również w Wersalu król Francji Ludwik XIV. W okresie tym oranżeria i parter pomarańczowy stały się znaczącym eremem ogrodowej kompozycji i programu. Wielkim miłośnikiem uprawy roślin cytrusowych był także elektor saski i król Polski August II Mocny. Podobnie jak Kosma I Medyceusz, utożsamiał się on z mitycznym Heraklesem, a w swych ogrodach w Dreźnie i Warszawie zgromadził olbrzymią kolekcję tych roślin - zwłaszcza pomarańczy gorzkiej. Uprawą cytrusów pasjonował się również ostatni król Polski, Stanisław August Poniatowski, a także car Aleksander II, który odkupił część kolekcji Augusta oraz wybudował nową oranżerię w parku łazienkowskim w Warszawie w celu jej utrzymywania.
The history of growing citrus plants dates back to ancient times but in the Renaissance era they gained particular importance as an element of garden art. At that time they became popular for their decorative and symbolic significance, as well as their originally intended purpose. The first documented use of citrus fruit as “garden art” took place in the garden of the Medici at Castello near Florence. During this period, citrus fruits were identified with the mythical “golden apples” of Hesperides. This fact was used by the Medici family in the garden to create a political message. The great collection of container plants including citrus was also held in Versailles, by French King Louis XIV. From that time the conservatory and orange parterre have become a sig- nifi cant element of garden composition and program. The Elector of Saxony and the King of Poland - August II the Strong was also a great lover of citrus fruits. Similar to Cosimo I de’ Medici, he identified himself with the mythical Heracles, and in his gardens in Dresden and Warsaw amassed huge collections of those plants - especially the bitter oranges which bear “golden” fruits. The last Polish king, Stanislaw August Poniatowski, was fascinated by citrus cultivation, as was Tsar Alexander II, who repurchased part of August II collection and built a new orangery in Lazienki Park in Warsaw for its maintenance.

Opis:
Minerals content of Citrus jambhiri (rough lemon) fruit was qualitatively and quantitatively analyzed using atomic absorption spectroscopy (AAS) and flame atomic emission spectrometry (FAES). The peel, moisture and ash contents of rough lemon were found to be 18.35 %, 23.75 % and 2.04 % respectively. Vitamin C (ascorbic acid) of rough lemon juice was found to be 70.0 mg/100 g. The chemical composition of essential oil of rough lemon peel was determined. The major compound was found to be limonene (84.5 %) followed by sabinene, β-myrcene, α-terpineol, 1,3-tetradecadiene and linalool.
