Differences in the carotenoid profile of commercially available organic and conventional tomato-based products
submitted by venad3116 2 hours ago - Topic: Agriculture
Carotenoids are important antioxidant compounds in the human diet. Due to their constrained polyene structure, carotenoids can exist in cis and trans isomeric form. In ketchups and tomato juices, all-trans isomeric forms are predominant. The aim of this study was to compare the carotenoid content and lipophilic antioxidant capacity of organic and conventional tomato-based products (tomato juice...



Antioxidant capacity of small dark fruits: Influence of cultivars and harvest time
submitted by venad3116 2 hours ago - Topic: Agriculture
Small dark fruits represent one of the most important sources of bioactive compounds with antioxidant capacity in the human diet. The content of health-promoting antioxidants in these fruits may be important information to take into account when a fruit producer has to choose which cultivar to grow. It is important to know how antioxidant capacity and antioxidant compounds as total phenolics an...

Effect of fertilization, tiller cutting and environment on plant growth and yield of European blueberry (Vaccinium myrtillus L.) in Norwegian forest fields
submitted by venad3116 2 hours ago - Topic: Agriculture
European blueberry (E. blueberry; Vaccinium myrtillus L.) is a natural resource demanded by the processing industry with potential of domestication. Therefore an investigation of the possibilities of partial cultivation of native stands was started. To increase knowledge of how E. blueberry react to soil types, climate, mineral nutrition, organic amendments and cutting of tillers. METHODE: Five...

Improved color and anthocyanin retention in strawberry puree by oxygen exclusion
submitted by venad3116 2 hours ago - Topic: Agriculture
Strawberry puree color is unstable during processing and storage due to oxidative reactions. To determine if strawberry puree prepared under nitrogen or carbon dioxide would result in greater retention of color and anthocyanins than samples prepared under air. Purees prepared under carbon dioxide, nitrogen or air were pasteurized and stored at 25°C. Samples were evaluated one day, and at two w...

New insights on the bacterial canker of kiwifruit (Pseudomonas syringae pv. actinidiae)
submitted by venad3116 2 hours ago - Topic: Agriculture
Since 2008, Pseudomonas syringae pv. actinidiae, the causal agent of bacterial canker of kiwifruit has become the main pathogen of yellow and green fleshed kiwifruit. All major kiwifruit producing countries in the world have been affected by this bacterial pathogen, leading to substantial economic losses. This review presents the current knowledge on various aspects about the origin, epidemiolo...



Echinococcus granulosus and other intestinal helminths: current status of prevalence and management in rural dogs of eastern Australia
submitted by ono 2 hours ago - Topic: Agriculture
Ascertain the prevalence of intestinal helminths in rural dogs from eastern Australia and Tasmania. Identify farm management practices contributing to the perpetuation and transmission of Echinococcus granulosus. Helminth infection in dogs was determined microscopically through faecal flotation. Infection with E. granulosus was determined via faecal antigen-capture ELISA and coproPCR. Taeniid e...

Characterization and mapping of a spotted-leaf genotype, splY181 that confers blast susceptibility in rice
submitted by rozon44 3 hours ago - Topic: Agriculture
A spotted-leaf mutant Y181, produced by 60Coγ-radiation treatment of Zixuan1, was identified in rice. The result of TEM demonstrated the number of starch grains decreased significantly, the distribution and volumes of osmiophilic granules and lipid balls were larger in the leaf cells around the lesion mimics, the chloroplasts in mesophyll cells disappeared and just leaving a few rupture thylak...


Gene expression analysis of peach fruit at different growth stages and with different susceptibility to Monilinia laxa
submitted by rozon44 3 hours ago - Topic: Agriculture
Monilinia brown rot is one of the most important diseases of peach (Prunus persica L. Batsch). In this study, the susceptibility to Monilinia rot of peach fruit during ripening was analysed weekly by assessing infected fruits upon artificial inoculation. Fruit drastically reduced their susceptibility to Monilinia rot along with ripening, becoming resistant in correspondence to pit hardening (a ...

Effects of mating patterns on reproductive performance and offspring fitness in Cryptolaemus montrouzieri
submitted by pallykario 3 hours ago - Topic: Agriculture
We examined the female mating choice of Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) when exposed to a male with which she had mated before vs. a novel male which she never encountered. After first mating, most females chose to remate with the same male and showed a shorter mating latency period to copulation with the familiar male as compared to a new male. Then, we allowed a ...


Biology of Lysiphlebus fabarum following cold storage of larvae and pupae
submitted by pallykario 3 hours ago - Topic: Agriculture
Cold storage is one means of preserving parasitoids prior to release in augmentation biological control programs. This study examined the feasibility of storing larval and pupal stages of a sexual population of Lysiphlebus fabarum Marshall (Hymenoptera: Braconidae: Aphidiinae) at 6 ± 1 and 8 ± 1 °C, 50–60% r.h., and L14:D10 photoperiod. These life stages were stored for periods of 1, ...

Impacts of elevated CO2 on Bemisia tabaci infesting Bt cotton and its parasitoid Encarsia formosa
submitted by pallykario 3 hours ago - Topic: Agriculture
Atmospheric carbon dioxide concentration is expected to rise in the coming decades. Rising atmospheric CO2 levels may alter plant-insect-parasitoid associations due to the indirect effects of CO2 enrichment on phytochemicals important for herbivore and parasitoid nutrition. Tritrophic effects of elevated CO2 on Bt cotton (GK-12) and non-transgenic (Simian-3, or S3) cotton [Gossypium hirsutum L....


Population structure of Spodoptera frugiperda maize and rice host forms in South America: are they host strains?
submitted by pallykario 3 hours ago - Topic: Agriculture
Determining which factors contribute to the formation and maintenance of genetic divergence to evaluate their relative importance as a cause of biological differentiation is among the major challenges in evolutionary biology. In Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) two host strains have been recognized in the 1980s: the corn-strain prefers maize, sorghum, and cotton, whereas t...
