بررسی جوانه‌زنی و رشد گیاهچهminor L. Sanguisorba تحت تأثیر سطوح مختلف کادمیوم

Sanguisorba minor belong’s to rosaceae’s family, and is one of the most valuable and most palatable pasture plant that in addition to value of feed, has conservation value for soil. Presence of heavy metals is considered as one of the major environmental stress. Accordingly , the effect of different concentration of heavy metal cadmium on growth and pullulation of sanguisorba minor was conducted in a completely randomized design with 3 replications. Expriment treatment include cadmium(10, 20, 30), was in milligram per litre. Aquapura was considered as the control treatment. In this research seeds with high viability were selected and after disinfection were cultured. After 10 days and completion of pullulation, then length of stipes and rootlet were measured. Results show of analysis of variance and mean comparison of data showed that there was no significant difference between different levels of cadmium on germination percentage and rate. But there was significant difference in other features( rootlet’s length, stipes’s length, plant’s length, seed’s length ).
