| Abstract: |
Boron is a unique micronutrient with narrow margin between deficiency and toxicity. It is considered to be phloem immobile or to have only limited phloem mobility in many higher plant species, where it is transported along the transpiration stream and accumulates in the margins of leaves. However, one would expect a phloem transport of boron if the back diffusion into the xylem in some way be prevented. The back diffusion into the xylem may only be possible under reduced transpiration. In the present research, the distribution of foliar-applied B in green gram plants (Vigna radiata L.) under varying transpiration rates was evaluated in the Plant Nutrition greenhouse at the University of Bonn, Germany, between July and September 2009. The experiment was laid out in a Complete Randomized Block Design (CRBD) comprising three moisture levels (75, 50 and 25 % WHC), two boron levels (100 and 0 mM B)……………………. |
