Evaluation of sowing value and vigor of dressed grain of winter triticale and rye depending on the cultivar and period of storageOcena wartości siewnej i wigoru zaprawionego ziarna pszenżyta ozimego i żyta w zależności od odmiany i okresu jego przechowywania

Abstract

Summary The two, two-factorial laboratory experiments were carried out at the Agronomy Depa rtment of Poznan University of Life Sciences. The first factor of first experiment considered were winter triticale cultivars: Fidelio, Woltario, and in the second experiment winter rye cultivars: Arant, Gradan, Nawid. Cereal grain was dressed with fludioxonil (winter triticale) and karboxin + thiram (winter rye). The second experimental factor was a storage period of grain. The grain was evaluated directly after dressing and 180 days after the treatment. The results of the studies revealed that the cultivar Fidelio was characterized by a higher sowing value of grain and vigor than the cultivar Woltario. Six-month storage period of dressed grain of winter triticale caused a significant reduction in grain germination capacity, a simultaneous increase in the number of dead grains as well as a deterioration of grain vigor parameters. In the experiment with rye the best of sowing value showed the cultivar Nawid and the worst one the cultivar Arant. A half year storage period decreased germination capacity of the dressed grain, but did not significantly influence its vigor.
