Boron in Plants (part 1)

Share | 2016-05-30 18:22:38 From:topfert Comment:0 Look:2451 [ L M S ]
Boron uptake by plants

Boron uptake by plants is controlled by the boron level in soil solution rather than the total boron content in soil. Boron uptake is a passive (non-metabolic) process. It moves with water in plant's tissues and accumulates in the leaves; therefore, Boron uptake and accumulation are directly dependent on the rate of transpiration.

Boron mobility in the phloem is now known to be plant-specie dependent.
