Hello Jhony, I think it is obvious. The larger the plant, the more the number of roots required to support it. Not just the number, but also the size increases and permeability increases. This is one of the factors on which plant-metal uptake and subsequent transport depend. See the document attached. I consider it a masterpiece.

Thanks Dr. Maurice Ekpenyong.

I feel , its strongly related .But uotake would e linked to the growth stage where root flush is maximum since it will generate consequently higher density of nutrient transporters embedded in plasmalema of root cells..

Thanks Dr. Anoop Kumar Srivastava.

Thanks Dr. Frances Bekele.

There is a transition from juvenile to mature growth which also influences growth rate ( need for nutrients) and partition. Worthy of investigation. We have done pot based update experiments on cadmium by cacao. Contact Paul Hadley or Jim Dunwell at University of Reading.

Dear Dr. Nicholas Cryer, thanks for your response.
