abstract
After zinc stress the total micropore volume
decreased remarkably while the average micropore radius increased
remarkably for the rye roots. Pore size distribution functions of
the roots after the additional zinc application showed the decrease
of the small micropore fraction from ca 2 to 10 nm and the increase
of the large micropore from ca 22 to 50 nm. The root surface pores
were fractal. After the stress pore fractal dimension increased. The
changes of the microporosity observed in the roots surface can be
related to the high content of zinc in the cell wall and/or due to the
shortage of Ca+2 the intercellular spaces particularly in the tissues
of seminal cortex of the studied roots might have grown.
