dc.description.abstractThe aims of this study were: to assess the effects of drought stress on germination percentage, germination energy and number of days to complete germination in fifteen tomato populations; to distinguish the treatment that is the most suitable for classifying the tomatoes for their response to early-imposed drought; as well as to distinguish populations which could be used for breeding tolerant varieties. The experiment included control germination assay (distilled water) and the increasing (4, 8, and 12%, w/v) polyethylene glycol (PEG) treatments. Both germination percentage and energy considerably decreased with the increasing PEG treatments, while the observed average increase in the number of days required to complete germination remained statistically insignificant. The differences in germination among the populations were most pronounced in 12% PEG treatment, which is therefore recommended for further research. Several populations are indicated as tolerant; however, tomato drought tolerance exhibited as early as at the germination stage does not necessarily indicate the tolerance in later phases of plant development. The population 105 is recommended for breeding drought tolerant varieties.en
dc.description.abstractCilj ovog istraživanja je bila procena efekata sušnog stresa na klijavost, energiju klijanja i broj dana do završetka klijanja kod petnaest populacija paradajza; utvrđivanje tretmana koji je najpogodniji za klasifikaciju paradajza na osnovu tolerantnosti na sušu u ranim fazama životnog ciklusa; kao i identifikacija populacija koje bi mogle biti iskorišćene za oplemenjivanje. Ogled je podrazumevao kontrolu (klijanje u prisustvu destilovane vode) i rastuće (4, 8 i 12%, w/v) tretmane polietilen-glikolom (PEG). Klijavost i energija klijanja su bili značajno niži u prisustvu PEG-a. Razlike u klijanju među populacijama paradajza su bile najizraženije kod tretmana 12% PEG, stoga se ovaj tretman preporučuje za dalji rad. Međutim, tolerantnost paradajza na sušu u fazi klijanja nije obavezno indikator tolerantnosti na ograničenu obezbeđenost vodom u kasnijim fazama razvoja biljke. Populacija 105 bi se mogla iskoristiti za oplemenjivanje paradajza tolerantnog na sušu.sr
