Mango is a kind of native fruit which can grow well as natural vegetation throughout the entire country under the various climatic conditions. We aimed to point out overuse of insecticide application in agricultural sector of Myanmar and further criteria of effective fruit fly control techniques were also proposed for worldwide ecosystem. Traditional fruit fly control is primarily focused on the uncoordinated use of insecticide applications which is orchard-by-orchard strategy. However, in view of flying distance, this localized strategy is not successful and harms the ecosystem. Occasionally, fruit bagging technique was applied by some farmers. In Myanmar’s agricultural sector, numerous varieties of cheap insecticides which mostly imported from China were plentiful. While conventional insecticide application controls were implemented annually, the population of fruit flies increased year after year, particularly in tropical region. The requirement of technical-scientific research reduced the worldwide fruit fly records. Furthermore, traditional insecticide application approach inhibits the yield and quality of mangoes that have adversely affected international trade. Importantly, in long term period of the entire previous decade, the conventional insecticide application controls make more fruit fly infestation.</span>展开更多

Fruits consumption frequencies were obtained from analysis of chimpanzee faecal samples picked over a period of two years. Fruit content was analyzed using freeze dried fresh samples using standard techniques. Musanga leo-errerae (76.14%), Ficus spp (66.05%) and (18.68%) were the most commonly eaten fruits of all faecal samples (N = 2683). Generally, fruit consumption increased for fruits with total phenols and tannins below 1% per gram except for Musanga leo-errerae, Uvariopsis congoensis and Aframomum angustifolium. Multiple regression revealed that of the 15 nutrient parameters investigated, only calcium, tannins, crude fat, protein and energy content of the fruits that constitute the major food components for basic animal body needs and functioning of energy, body building and a healthy skeleton significantly predicted 76.86% of consumption (R2 = 76.86%;P = 0.019). However, the fact that some of the most eaten fruits like Aframomum angustifolium and Musanga leo-errerae were recorded to have the highest amounts in tannins shows that there must be additional factors into play. Other than fruit availability, consideration of effect of fruit size and handling within the existing models of chimpanzees’ diet could hence enhance further the understanding of fruit consumption.展开更多

The objective of this study was to determine the standards applicable to the types of juice for domestic consumption in Lubumbashi. A descriptive cross-sectional study on quality control (QC) of ten brands of juice selected from around thirty listed on the Lubumbashi markets focused on the determination of different physico-chemical and microbiological parameters. Physical analysis of the juices was carried out in the laboratory of the Congolese Office of Control (OCC) in February 2019. It appears that five samples, or 25%, have a density lower than the ISO 9001 standard. All the samples have a Brix Degree in accordance with French standards applicable by the Congolese control office. The chemical analysis shows that 4 samples, or 20%, have a pH 4, therefore higher than the prescribed standards. As for the titratable acidity and the formaldehyde index, all the samples have values within normal limits. On the other hand, the glucose level of all the samples is abnormally high (≥40 g/L). The sucrose level of 50% of the samples is normal (≥80 g/L). Microbiological analysis revealed that certain juices were without preservatives and harbored aerobic mesophilic germs (10%), lactic bacteria (20%) yeasts and molds (10%). It is urgent that the public authorities bring all the producers to respect the standards in order to protect the health of the populations.展开更多

Growth in height was measured with the same birth cohorts, not by comparing mean height of ascending ages in the same year. Starting from a lower economic base and mean height in the 1960s, high school males aged 17 in South Korea became 3 cm taller in mean height than their Japanese peers in the mid-2000s versus 2 - 3 cm shorter in the 1960s through 1970s. Children in Japan ceased to grow taller by the end of the 1980s, not because they quit taking more animal-sourced foods, meat and milk, but because they had drastically steered away from fruit and vegetables in their diets since the end of the 1970s. Having largely converged economically with Japan, South Korean children ceased to grow any taller in the mid-2000s. More importantly, it was discovered in this study that successive cohorts in South Korea started to fall gradually but steadily in height growth velocity from 1<sup><span style="font-family:Verdana;font-size:12px;">st</span></sup><span style="font-family:Verdana;font-size:12px;"> graders in middle school, aged 12 years to 3</span><sup><span style="font-family:Verdana;font-size:12px;">rd</span></sup><span style="font-family:Verdana;font-size:12px;"> graders in high school, </span><span style="font-family:Verdana;">and </span><span style="font-family:Verdana;">aged 17 years, to be once again 3 cm below their Japanese peers in the early-2010s. Analysis of Korea Household Expenditure Surveys classified by age groups of household head, decomposed by the author, revealed that children under 20 years of age in South Korea began to steer away from fruit and, particularly, vegetables in their at-home consumption in the mid-1990s, to average only 15% of the level of older adults in their 50s in the mid-2010s. These results lend supports to the importance of fruit and vegetables as determinants in height and its growth velocities in two genetically similar nations over time and stages of ec展开更多

This study aimed at evaluating the influence of N, P and K on some physico-chemical and organoleptic characteristics of pineapple (Ananas comosus L. Merr) for fresh consumption and juice processing. A complete NPK factorial design was installed in the south Benin. The treatments NPK in g plant-1 were randomized into four blocks: T1;T2;T3;T4;T5;T6;T7;T8;T9. Brix juice was determined using a refractometer and pH with a pH meter. An evaluation of sensory characteristics such as sweetness, acid taste and aroma of fresh pineapple pulp and processed juice was made by a panel of tasters selected and trained. A principal components analysis, followed by a numerical classification was performed on fruits’ sensory and physicochemical characteristics. Results showed that juice pH was significantly influenced by the phosphorus and potassium. Potassium influenced significantly juice yield. Some physico-chemical characteristics and sensory attributes were correlated between them and groups of treatments are formed for both the juice and the fresh fruit.展开更多

Although the cultivation of the tung tree produces great economic value, some important genetic and physiological traits in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;"> have not been fully recognized. As one of them, the effect of pollen on the maternal plant (xenia) is unknown in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;">, which is an important part of the efficient cultivation system of many crops. This study performed hybridization with three important tung cultivars (Dami, Xiaomi and Putao) to evaluate the influence of pollen source on fruit and seed development. The results revealed that xenia is present in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;">, which influences fruit setting, fruit size, seed weight and oil content. Among the cultivars investigated, the hybridization combination with Putao as a female parent and Dami as male parent showed significant improvement of seed yield and oil content than self-pollination, which could be considered to apply in practice.展开更多

文摘The paper compares the height growth velocities of male schoolchildren in South Korea and Japan over the period 1961-2018. Growth in height was measured with the same birth cohorts, not by comparing mean height of ascending ages in the same year. Starting from a lower economic base and mean height in the 1960s, high school males aged 17 in South Korea became 3 cm taller in mean height than their Japanese peers in the mid-2000s versus 2 - 3 cm shorter in the 1960s through 1970s. Children in Japan ceased to grow taller by the end of the 1980s, not because they quit taking more animal-sourced foods, meat and milk, but because they had drastically steered away from fruit and vegetables in their diets since the end of the 1970s. Having largely converged economically with Japan, South Korean children ceased to grow any taller in the mid-2000s. More importantly, it was discovered in this study that successive cohorts in South Korea started to fall gradually but steadily in height growth velocity from 1<sup><span style="font-family:Verdana;font-size:12px;">st</span></sup><span style="font-family:Verdana;font-size:12px;"> graders in middle school, aged 12 years to 3</span><sup><span style="font-family:Verdana;font-size:12px;">rd</span></sup><span style="font-family:Verdana;font-size:12px;"> graders in high school, </span><span style="font-family:Verdana;">and </span><span style="font-family:Verdana;">aged 17 years, to be once again 3 cm below their Japanese peers in the early-2010s. Analysis of Korea Household Expenditure Surveys classified by age groups of household head, decomposed by the author, revealed that children under 20 years of age in South Korea began to steer away from fruit and, particularly, vegetables in their at-home consumption in the mid-1990s, to average only 15% of the level of older adults in their 50s in the mid-2010s. These results lend supports to the importance of fruit and vegetables as determinants in height and its growth velocities in two genetically similar nations over time and stages of ec

文摘Fertilization practices can influence the quality of pineapple fruit and consequently its acceptability by consumers who are increasingly oriented towards high quality agri-food products. This study aimed at evaluating the influence of N, P and K on some physico-chemical and organoleptic characteristics of pineapple (Ananas comosus L. Merr) for fresh consumption and juice processing. A complete NPK factorial design was installed in the south Benin. The treatments NPK in g plant-1 were randomized into four blocks: T1;T2;T3;T4;T5;T6;T7;T8;T9. Brix juice was determined using a refractometer and pH with a pH meter. An evaluation of sensory characteristics such as sweetness, acid taste and aroma of fresh pineapple pulp and processed juice was made by a panel of tasters selected and trained. A principal components analysis, followed by a numerical classification was performed on fruits’ sensory and physicochemical characteristics. Results showed that juice pH was significantly influenced by the phosphorus and potassium. Potassium influenced significantly juice yield. Some physico-chemical characteristics and sensory attributes were correlated between them and groups of treatments are formed for both the juice and the fresh fruit.

文摘To gain insight into the molecular and genetic basis of fruit size and shape in cucumber,we conducted Quantitative Trait Locus(QTL)mapping with F2 and BC1F1 populations derived froma cross between the Northern-China type inbred line CNS21 and the Southern-China type inbred line RNS7.Populations were evaluated during two developmental stages,ovary at anthesis and commercial fruit(immature fruit).A total of 13 major-effect QTLs(R2>10%)were detected for six traits,and one of them,fruit shape index 2.1,explained more than 50%of phenotypic variation.All QTLs distributed on chromosome(chr)1 and 2.We constructed a physical map containing almost all of the QTLs with their physical location from previous studies.For fruit size and shape,the highest number of QTLs were mapped on chr1 and chr6,and the fewest number were mapped on chr2 and chr7.At least one consensus region was presented on each chromosome.In addition,three candidate genes were predicted between the long-fruited and round-fruited inbred lines by comparing the sequences of the consensus region of chr3,where many QTLs for marketable fruit length had been detected.Our results provide a base for additional QTLs and molecular markers for fruit size and shape in cucumber breeding.
文摘Tung tree, </span><i><span style="font-family:Verdana;">Vernicia fordii</span></i><span style="font-family:Verdana;">, is a plant species producing industrial oil (tung oil). Although the cultivation of the tung tree produces great economic value, some important genetic and physiological traits in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;"> have not been fully recognized. As one of them, the effect of pollen on the maternal plant (xenia) is unknown in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;">, which is an important part of the efficient cultivation system of many crops. This study performed hybridization with three important tung cultivars (Dami, Xiaomi and Putao) to evaluate the influence of pollen source on fruit and seed development. The results revealed that xenia is present in </span><i><span style="font-family:Verdana;">V. fordii</span></i><span style="font-family:Verdana;">, which influences fruit setting, fruit size, seed weight and oil content. Among the cultivars investigated, the hybridization combination with Putao as a female parent and Dami as male parent showed significant improvement of seed yield and oil content than self-pollination, which could be considered to apply in practice.
