The influence of copper on seeds germination of some coastal and sea halohpytic plants (Chenopodiaceae)

The results of researches of heavy metals con-centration in sea water of littoral area and soil of supralittoral area of the north-eastern part of Uglovoi Gulf of the Japanese sea are given in the study. It was shown that the concentration of plumbum and cadmium significantly decreased and the concentration of cooper increased in sea water in the period from 2010 to 2015. It was established that at the same time there was similar process of cooper accumulation in the soil of a supralitoral zone. The accumulation of heavy metals in vital organs of plants leads to the inhibition of the plant growth and development processes and also to their death. It is known that an excess concentra-tion of cooper has toxic influence on the plants. The influence of high cooper concentration on the main characteristics of seeds germination of coastal hal-ophytic plants Salicornia perennans and Suaeda heteroptera (Chenopodiaceae) was studied. Spe-cies of specific inhibition of germination, especially of Salicornia perennans seeds were shown. The percentage of germination of the Salicornia perennans seeds decreased, moreover its energy and speed decreased too. And Suaeda heteroptera had only slightly decreased the number of viable seeds. While in Suaeda heteroptera the quantity of viable seeds decreased insignificantly
