LOW-LEVEL RADIATION AND PHYTOSANITARY MONITORING OF PERENNIAL FODDER GRASS SEEDS

During the periods of high solar activity, the prevalence and damage of perennial grasses by leaf pathogens in the village of Belogorka, Leningrad Region, have nearly always been high. Our xFestulolium hybrids which were heterotic in terms of vegetative weight, showed tolerance to solar radiation. The pathogen combination of net blotch and rust inhibited magnetic field strength in sensitive plants (S) of meadow fescue, sample 1/9 (Tomsk region) - 98,7 ?T in S-plants in comparison with 126,8 ?T in resistant (R) plants.
