The effect of selenium micronutrient fertilizers on fotometricheskie signs of winter rye seedlings

In order to identify and assess the effect of selenium on the phytometric characteristics of winter rye seedlings, a laboratory experiment on the germination of seeds of 25 population varieties by the method of roll culture was laid. The experimental scheme included 2 variants of germination conditions: in 0.03% solution of selenium microfertilizer "Non-settled" (experimental variant) and in water (control variant). It is established that in conditions of germination with 0.03% sodium content of the micronutrient selenium (in the form of village-Nita sodium) significantly increased the average biomass of shoots (25%), length of sprouts (24%), root length (18%), the biomass of roots (13%), the number of KOR-it (12%), germination (8%). It is noted that in the conditions with selenium the values of signs varied less: on average, the coefficient of variation was 5-16% compared with 13-29% in the control conditions. The force of influence on the studied signs of the factors "variety", "conditions" and their interaction is determined. The factor "grade" had the strongest impact on the phytomass of roots, the factor "conditions" to the length of the roots, the interaction "variety x conditions" on the number of roots. In the presence of selenium in the germination medium, the varieties develop stronger signs of germs (phytomass and length), as well as the length of the root. In 60% of the sample in conditions with selenium there was a significant increase in comparison with the control on at least one basis. Most often, the varieties exceeded the control on the grounds of roots (number, length, phytomass). Grade Snezhana C30/07 was characterized by higher rates on all grounds. Significantly high values (relative to overall average) in root length was observed in the varieties of Rumba, (13,4 cm), pitomac lo-roots – varieties of Quail and Falenskoe 4 (1.25 g).
