Abstract:Iron (Fe) deficiency restricts crop yields in calcareous soil. Thus, a
novel Fe chelator, proline-2′-deoxymugineic acid (PDMA), based on the
natural phytosiderophore 2′-deoxymugineic acid (DMA), was developed to
solve the Fe deficiency problem. However, the effects and mechanisms of
PDMA relevant to the Fe nutrition and yield of dicots grown under field
conditions require further exploration. In this study, pot and field
experiments with calcareous soil were conducted to investigate the
effects of PDMA on the … Show more
