Object of study: ordinary barley (Hordeum vulgare L.), Sem. grasses (Poaceae) Objective: To study the effect of spermine on the growth processes in barley seedlings ordinary at the effects of various stressors (hypo-, hyperthermia, heavy metals);

Methods: water culture, morphometry, test the growth of coleoptile segments .

Results of: spermine revealed inhibitory effect on the growth of leaves and roots of barley seedlings. It is shown that the effect of inhibiting the growth of barley seedlings characteristic for all the studied concentrations (10 9103 mol/l) of spermine. The greatest reduction in growth of roots observed (approximately 2 fold) for the leaves (about 30%) compared with control plants .

It is shown that spermine concentrations 109103 mol/l inhibited the growth of tension (the dough rise coleoptile segments). Set the maximum growth inhibitory concentration of spermine (103 mol/l). Reduced lengths of the coleoptile growth was 20% .

Showing the influence of temperature effects on the growth of tension under the action of spermine. 4 C temperature leads to a decrease of growth of coleoptiles stretching segments. Elevated temperature (32 C), on the contrary it increases. Contact dose-spermine is conserved in all cases .

In experiments on the effects on the growth of above-ground and root portions of barley seedlings heavy metal ions, for example nickel, while the action of spermine and of histidine has been shown that nickel causes inhibition of the growth process, with the effect of reducing the growth of leaves and roots when compounded in the presence of growth medium spermine and histidine. Test segments coleoptile elongation growth indicates readily achievable response to the presence in the incubation medium of spermine and they appear in the first night of observations .
