摘要：Cilj ove studije je bio da se utvrdi klijanje semena Cuscuta campestris pri različitim koncentracijama soli,što bi moglo ukazati na mogućnost predviđanja njenog širenje na područja sa zaslanjenim zemljištem.Semena viline kosice su stavljena u Petri posude sa po 5 mL rastvora sa različitim koncentracijama NaCl (5,10,20,40,80,160,320 µM).Voda je služila kao kontrolna varijanta.Broj klijalih semena beležen je svakodnevno (stopa klijanja),a konačni procenat klijavosti i dužine klijanaca su izmereni nakon 18 dana.Svi tretmani su izvedeni u mraku u inkubatoru na 25°C.Povećanjem koncentracije soli,uočena je tendenciju smanjenja klijavosti kao i dužine klijanaca.Procenat klijanja kreće se od 0,0% (u 320 µM NaCl) do 82,1% (u 5 µM NaCl),dok je u kontrolnoj varijanti bio 92,5%.Dužina klijanaca varira od 2,2 cm do 8,5 cm,a stopa klijanja se kreće od 7,7 do 20,1.
其他摘要：The aim of this study was to determine the reaction of Cuscuta campestris Yunck.at different salt concentrations,due to the possibility of predicting its spread to areas with saline soils.Seeds of field dodder were placed in Petri dishes filled with 5 mL of salt solution with different concentrations of NaCl (5,10,20,40,80,160,320 µM).Only water was added to the control treatment.The number of germinated seeds was recorded daily (germination rate),and the final percentage of germination and seedling length were measured after 18 days.All of the experiments were carried out in the dark,in an incubator at 25oC.Germination percentage was negatively affected by salt concentrations in Petri dishes.Increasing salt concentration tended to decrease the germination and seedling length.Final percentage of germination ranged from 0.0% (in 320 µM NaCl) to 82.1% (in 5 µM NaCl),while it was 92.5% in the controltreatment.Seedling length ranged from 2.2 cm to 8.5 cm and germination rate ranged from 7.7 to 20.1.
