Klijavost semena pasulja i boranije
Germination of beans and snap beans seed
MetadataShow full item record
Laboratorijskim ispitivanjem klijavosti obuhvaćeno je seme pasulja i boranije u sledećim varijantama: seme pasulja dobrog izgleda, seme pasulja lošeg izgleda, seme pasulja i boranija sa jasno vidljivim tragovima oštećenja pasuljevim žižkom i seme visoke linije boranije. Ogled, je postavljen kao dvofaktorijalni-blok sistem, u kojem je drugi faktor, pored genotipa, bilo tretiranje semena zamrzavanjem. Dobijeni rezultati ukazuju daje seme pasulja loše frakcije bilo najslabije klijavosti, ali da je ona prisutna. Iako je seme dobrog izgleda pažljivo odabrano, klijavost je nešto ispod standarda zakonom dozvoljene klijavosti. Seme sa izraženim prisustvom pasuljevog žižka, je u laboratorijskim ustavima zadržalo klijavost u značajnom stepenu. Između pasulja i boranija nema razlika u pogledu klijavosti. U poređenju semena ne tretiranog i tretiranog zamrzavanjem ne postoje razlike između pasulja i boranija.
The aim of this study was to investigate germination of good bean seed of the variety Galeb and the bad bean seed of the same variety. We were also interested in germination of bean and snap bean seed damaged by grain weevil, and in germination of the seed treated by freezing which was aimed at controlling grain weevil by cold. We also recorded the differences between bean and snap bean seed, which was or was not treated by freezing in laboratory conditions. This investigation was carried out by applying the two factorial block system. The obtained results were evaluated by the variance analysis and x2 test These results suggest that the bean seed of a bad fraction had low levels of germination, but still it was present. Although the seed of good appearance was carefully selected, germination was slightly lower than it should have been. The seed with the large amount of grain weevils performed a high level germination in laboratory conditions. There were no differences in germination b...etween the seed injured by grain weevil either in beans or in snap beans. As for the seed treated or untreated by freezing, there also were no differences between beans and snap beans.
