Abstract:
... In this paper, a forward osmosis (FO) process has been proposed to extract clean water from the micro-polluted feed containing heavy metal ions using biogas slurry as the draw solution, and then the diluted biogas slurry was directly utilized as a hydroponic solution to cultivate rice and leek without further treatment. In this process, the Cd2+ and Pb2+ ions, in the feed solution were effectively ...

Abstract:
... Leek, Allium ampeloprasum L., is susceptible to attack by onion thrips, Thrips tabaci Lindeman, that reduce yield and quality. Intercropping has been proposed as a strategy for reducing negative effects of pests on one or all crops in a system. The objective of the study was to assess the effect of intercropping maize, Zea mays L., and leek on abundance of thrips and production and morphology of b ...

Abstract:
... Leek is an economically important vegetable. In model plants, the CONSTANS (CO) and CONSTANS-like (COL) genes play central roles in plant flowering modulation. However, none of leek CO homolog has been identified, because of limited gene resources obtained in this crop. Here, we reported the transcriptome analysis of leek, along with the identification of putative leek CONSTANS-like (COL) (ApCOL) ...

Abstract:
... The sustainability of agriculture can be improved by integrating management of ecosystem services, such as insect pollination, into farming practices. However, large‐scale adoption of ecosystem services‐based practices in agriculture is lacking, possibly because growers undervalue the benefits of ecosystem services compared to those of conventional management practices. Here we show that, under re ...
