Webb11 apr. 2024 · Movement of Ca 2+ toward leaves and fruits can be performed in both apoplastic and symplastic pathways (White and Broadley 2003 ). Ca 2+ moves in xylem vessel in chelate form and its movement is considerably dependent on the transpiration rate. In fact, low Ca 2+ content in plant tissues is a consequence of low transpiration rate … biofroxx公司是哪个国家的Webb30 apr. 2001 · The relative contributions of these two pathways to the delivery of Ca2+ to the xylem are unknown.
