Rezime: Cilj rada bio je da se ispita optimalno vreme potapanja semena soje i njegov efekat u uslovima sonog stresa. Testiranje je sprovedeno u Institutu za ratarstvo i povrtarstvo u Novom Sadu na semenu sorte Galina. Optimalno vreme utvrĎeno je potapanjem semena u prajmere: KNO 3 (1%), H 2 O 2 (0,1%) i H 2 O u trajanju od 6 h, 12 h, 18 h i 24 h. Posle sušenja do prvobitne vlage, seme je stavljeno na naklijavanje, a nakon 8 dana utvrĎena je klijavost. U drugom ogledu seme je potapano u prajmere: KNO 3 (1%), H 2 O 2 (0,1%) i H 2 O, a nakon toga ispitivan je njihov efekat na energiju klijanja i klijavost semena u uslovima simulirane zaslanjenosti. Simulirane uslove zaslanjenosti predstavljale su podloge za naklijavanje kojima je dodat rastvor NaCl u različitim koncentracijama (0, 50, 100, 150, 200 mM). Rezultati istraživanja su pokazali da je najbolje šestočasovno potapanje semena kod svih prajmera. Sa povećanjem vremena potapanja linearno se smanjuje procenat klijavosti semena. Istraživanja su pokazala i da potapanje semena predstavlja povoljnu tehniku za smanjenje negativnog uticaja NaCl na energiju klijanja i klijavost semena soje, a najbolji efekat ostvaren je upotrebom KNO 3 .
The paper describes the symptoms of the Fusarium wilt and necrosis of root and lower stem of soybean, which include leaf chlorosis, wilt of the apical portion of the plant, necrosis of the root and lower stem, and wilting of the whole plant. The pods are often poorly developed. The seeds may be smaller and lighter in the weight and infected, as well. Isolated from diseased soybean plants were the species Fusarium avenaceum, F. equiseti, F. oxysporum and F. poae. Pathogenicity tests under artificial infection conditions showed F. oxysporum (isolate S/1) to be the most pathogenic among of the four investigated species. The other species proved much less pathogenic
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
