Fig.7. Root meristematic cells in Triticum aestivum<br />
treated with MnSO4 0.0001% for 6 h. It can be<br />
observed cells without content and cells in prophase<br />
and cytochinesis. The nuclei are hypertrophic with<br />
obviously hetero-chromatinisations and<br />
vacuolisations (150x).<br />
Fig.8. Root meristematic cells in Triticum aestivum<br />
treated with MnSO4 0.005% for 6 h. It can be<br />
observed plasmolytic cells mixed with cells in<br />
prophase and telophase abnormal disposed and<br />
containing hypertrophic nuclei with obvious heterochromatinisations<br />
(150X).<br />

Fig.9. Root meristematic cells in Triticum aestivum<br />
treated with MnSO4 0.01% for 6 h. It can be<br />
observed abnormal disposed cells without content<br />
mixed with plasmolytic cells in witch we can<br />
observed an early chloroplasts formatting (600X).<br />
Fig.10. Root meristematic cells in Triticum<br />
aestivum treated with MnSO4 0.0001% for 24 h. It<br />
can be observed long cells disposed in lines; cells<br />
are plasmolytic, during prophase and in witch we<br />
can observed an early chloroplasts formatting<br />
(600X).
