Notwithstanding, it has been extensively cultivated outside its native range, so also has its pollinators been acquired and introduced. A concern, however is that most documentation on oil palm and its pollinators are non-indigenous, with little information of African origin commenting on their activities in Africa. Thus, a study on the insect pollinators of oil palm was carried out on two fruit forms: Dura and Tenera, (ages ten and seven, respectively), in Ghana. The aim was to understand how average monthly population density of the pollinators relates to one another, and to two bunch parameters (fruitset and fruit-to-bunch ratio). Nine species (all in the order Coleoptera) were consistently seen on the spikelets of anthesising male inflorescences, and eleven species on receptive female inflorescences. Six were of the Elaeidobius genus: E. kamerunicus, E. plagiatus, E. singularis, E. subvittatus, E. bilineatus, and Elaeidobius sp. 1 (unidentified species); two each were of the Microporum genus: M. congolenses, M. dispar, and the Prosoestus genus: P. scuptilis, P. minor; while one species was of either Atheta or Forficula. The pollinators were observed to be positively related, and to varying degree of significance. Fruitset level was acceptably high, indicating adequate pollinator population and efficient pollination. There was a positive relationship between population density of the pollinators and fruitset, and a negative relationship between the bunch parameters. A number of other insects were seldom observed around the male and female inflorescences; their role could not be defined.","PeriodicalId":19440,"journal":{"name":"OCL","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85942319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, more attention is paid to the issue of growing and processing sunflowers and all aspects of production that affect yield and quality. This is especially influenced by the large increase in sunflower prices on world markets in 2021, which will certainly continue in 2022, due to the war in Ukraine and the fact that production in Russia and Ukraine accounts for over 54% of world production. Investments in sunflower production are now becoming more profitable, but on the other hand, the price of all inputs, especially fertilizers, is also growing rapidly. This edition of OCL deals with a wide range of current topics, among which, new discoveries dominate in the field of breeding, cultivation in the conditions of global climate change and the fight against diseases, parasites and pests of sunflower. The basis of any breeding program is genetic resources. The activities of three gene banks, in USA, France and Serbia, are described in detail, supplemented by data from seven other countries (Terzić et al., 2020). Exploitation of heterosis for seed, oil yield and quality it is still in the focus of breeders (Ahmed et al., 2021). In assessment of phenotypic variability among INTA (Argentina) sunflower lines, authors demonstrated the need for more in-depth study of genetic variability to be used as a predictor of heterosis in sunflower (Dominguez et al., 2021). The high yield is ultimate goal but the compact habitus of sunflower plants (erectoid lives) is not a determining factor in the development of productivity of sowings with a high plant density (Bushnev et al., 2021). Researchers are apparently increasingly focusing on the impact of global climate change, especially high temperatures and drought. Authors (Berton at al., 2021) provided untargeted and targeted metabolomic data of sunflower leaves under water deficit. They constitute a valuable resource for the community to study the adaptation of crops to drought and the metabolic bases of heterosis. Innovative cropping systems based on low-input management, organic farming, soil and water conservation practices, intercropping, double-cropping, and/or agroforestry, so as new sunflower ideotyping are being investigated (Debaeke et al., 2021).

The aims of this study were to investigate the oil content and composition of chia seeds cultivated in two locations under organic conditions in southern West of France. As expected, location factor affected oil content. Moreover, this factor affected also fatty acid, sterols and tocopherols content and composition. Lavaur presented higher oil content than Samatan. This later location presented higher temperature during grain filling period. Polyunsaturated fatty acids were more represented at Lavaur than at Samatan. Saturated and monounsaturated fatty acids showed the opposite trends. Sterols and tocopherols were more accumulated in chia seeds at Lavaur. These results showed that all quality traits of chia seed cultivated in France were affected by climatic conditions prevailing in location of cultivation.","PeriodicalId":19440,"journal":{"name":"OCL","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83097939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its management has changed with the development of Ready-to-Use Therapeutic Foods (RUTF) that are energy-dense, lipid-based, micronutrient-enriched foods. The purpose of the present study was to define some aspects of the nutritional profile (in particular, lipid content, fatty acids profile, lipophilic vitamin content), oxidative status, and mycotoxin content of three RUTF products (of which two manufactured in Asia and one in Europe), at different time points during their storage. All RUTF displayed good lipid stability, with peroxide values < 10 meqO2/kg lipids, acidity index < 0.6 g/100 g lipids, and very low amounts of secondary oxidation volatile compounds. Only the one produced in Europe complied with the international recommendations on vitamin A and E contents. Lipid content ranged from 28.7 ± 0.5 to 41.2 ± 2.4 g/100 g. Oleic acid, palmitic acid, and linoleic acid (47.2 ± 7.4%, 26.8 ± 2.1%, and 12.4 ± 3.9% of total lipids, respectively) were the main fatty acids. Only one of the samples made in Asia exceeded the regulatory limit of mycotoxins. The RUTF lipid phase was rather stable at ambient temperature from 9 to 12 months, and appropriate packaging may have contributed to a major stability.","PeriodicalId":19440,"journal":{"name":"OCL","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74689212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

N-hexane and acetone were also used for comparison. Amplitude level and extraction time were the factors investigated concerning extraction yield. Comparative studies between traditional extraction methods and extraction assisted by ultrasonication have also been carried out. The astaxanthin content as total carotenoids in oil extract was analyzed using a UV-vis spectrophotometer with a standard external method.

Our outcomes revealed significant variations between EVOOs from both cultivars in terms of the investigated physicochemical characteristics. These were also affected by storage time and temperature except for fatty acids, for which storage time had no significant effects. While the changes in tocopherols showed a drastic reduction ranging from 48.18 (“Moroccan Picholine”) to 62.62% (“Arbequina”). Indeed, the changes of quality indices showed a linear increase. Moreover, “Arbequina” oil was the first to exceed the established upper limits for EVOO label. An increase in oxidation rate was observed with increasing temperature when oils were oxidized at six elevated temperatures (373, 383, 393, 403, 413 and 423 °K) under Rancimat test conditions. The natural logarithms of the kinetic rate constant varied linearly with respect to temperature, with temperature coefficient (TCoeff) ranging from 7.31 × 10−2 in “Arbequina” to 7.51 × 10−2 K−1 found in “Moroccan Picholine”. This had higher oxidative stability and shelf life as compared to “Arbequina”. These outcomes were confirmed by kinetic parameters of oxidative stability including reaction rate constant as well as Arrhenius equation and thermodynamic parameters.","PeriodicalId":19440,"journal":{"name":"OCL","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80426581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to evaluate the chemical composition and the physicochemical parameters of fixed oils produced by the argan trees introduced in Oujda City and to compare them with other oils produced by the same trees in their natural biotope in the northeast and southwest of Morocco. The obtained results indicated that the oil yield varies between 57.65% and 47.60%. The investigation of the chemical composition using HPLC-DAD showed the presence of three types of tocopherols: α-tocopherols (9.7%), δ-tocopherols (6.6%), and γ-tocopherols (83.6%), the total content of tocopherols vary between 323.86 and 553.12 mg/kg.

The physicochemical parameters (the free acidity, the peroxide value, and the specific extinction) indicated that the different tested oils are characterized by a good oil quality according to the Moroccan standard concerning argan oil (NM 08.5.090). The obtained results indicated that the introduced argan in Oujda City showed a quality and a chemical composition that was comparable to that produced in the natural area of the argan tree, which shows the plasticity the plant under different climatic and edaphic conditions.

Starting in 2010, after a short period of growing U.S. hybrids, superior Chinese proprietary hybrids were developed through contributions from both the private and public sectors utilizing old landraces, OPV and limited foreign germplasms as genetic resources which eventually enabled China to become a leading producer worldwide. The average yields have steadily increased from 1730 kg/ha (OPV) to over 2700 kg/ha (hybrid) largely due to genetic improvements and advanced cultivation practices. The planted area is expected to remain at around 0.60 M ha, with over 95% confection sunflower, and the remaining 5% oilseed type. Sunflower production in China is mainly concentrated in 10 provinces of the northwest region with around three-fourth of the production in Inner Mongolia, followed by Xinjiang. The potential for increased sunflower cultivation remains optimistic in those regions due to the benefit of an established industrial supply chain of producing, processing, and marketing near the production areas. More than half of all products is domestically consumed (∼2.0 M T/year), but overseas exports have gradually increased in recent years. Future directions for confection sunflower breeding should continue emphasizing high quality, multi-disease resistance, and product versatility to meet the diverse market demands. Further enhancement of variety registration and the implementation of DNA fingerprinting for variety identification will help the sustainable development of the Chinese sunflower industry.","PeriodicalId":19440,"journal":{"name":"OCL","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83915629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
