It will cause diseases for humans and animals when Se is excessive or lack in the environment.The research status of selenium-enriched agricultural crops and selenium-enriched horticultural crops, functional mechanism and application status of selenium, and the latest progress in the study of selenium enrichment were summarized in this paper.展开更多

In Ghana, crops such as pineapples and mangoes appear promising because of their high labour intensity and expanding demand for fruits in Europe. Notwithstanding, there is a possible trade-off between export and food crop production because of the possibility of resource re-allocation. So far the major concern of government has been the growth in export earnings while the micro-level distributional effects remain under-investigated. The study focused on a household survey undertaken in the forest and coastal-savannah transition zones, where the farming system has undergone transition from an established food-crop farming for urban markets to an intensive production of horticultural products for export. Logistic regression and Gini coefficient approaches were used to estimate the determinants of household food availability and income distribution respectively. Though, households engaged in export horticulture appear better-off than those that do not, the sole adoption of either staple or export crop is not sufficient for improving food availability. Consequently, linkages which allow simultaneous and reliably access to equitable distribution of resources and services are critical for household survival in competitive global food markets展开更多

The results of this type of analysis give an opportunity to distinguish the evaluated products from each other from a consumption point of view. In this paper, three Agaricus species （＂white button mushroom＂, ＂cream type＂ and ＂almond portobello＂）, were characterized by sensory profile analysis. The sensory attributes can have an influence on consumer product preference therefore it is essential to describe products, for example mushrooms. This is the first report which focus on describing the full sensory profile of these fresh mushrooms.展开更多

The garden between products and facilities due to capacity and the relative advantage in the production always plays an important role in the non-oil export. The aim of these studies of economic issues, is to analyze the major marketing dried fruit （pistachio, almond rock, walnuts, and walnut） in Fars province. In this study, information and statistics needed were collected through interviews with experts and Agriculture Organization of Fats province. For this purpose the method used in this study is commonly used in economic texts and retail margins and wholesale agents and share marketing costs with the market ratio. The results of this study indicate that factor market costs for pistachio, almonds, walnuts and Mghzgrdv are 30.340, 21.167, 16.794 and 17.061.展开更多

In terms of flower period Truwind M1 is early and 7 days, which is the suitable pollinator for‘Fengyue’;Truwind M2 is intermediate with 15 days,suitable for ‘Kuimi’and‘Lushanxiang’;Truwind M3 and M4 are 14 days and 13 days respectively,suitable for‘Cuiyu’and‘Miliang 1’;Truwind M5 is late and 8 days, suitable for‘Jinkui’,‘Qinxiang’and‘Hayward’.展开更多
