dc.description.abstractThe study includes research on the effect of ultrasound on the ability of seed germination and coleoptile development of cereal landraces (fam. Poaceae): oat (Avena sativa L.) brodski, rye (Secale cereale L.) rakotinska, Triticale svetinikolsko and soft wheat (Triticum aestivum L.) govrlevska. The experiment with ultrasound was carried out at frequency of 30-40 kHz on the thermostatic ultrasonic bath. Seeds were sonicated at a constant temperature (25ºC) for 15 min. Ultrasound effect is reflected in the length of the coleoptyl and mesocotyl, although in a good deal is genetically predetermined. Coleoptile length was the longest in Triticale (3.3-5.5 cm) and approximately the same lengths are evident in rye (3.0-6.1 cm). Concerning the mesocotyl the longest one (5.525 cm ± 0.697) is recorded at rye, even significantly longer than control of oat and Triticale. Longer coleoptile of sonicated seeds indicates faster seedling development, good water supply and rapid development and emergence of first leaves. Correlation coefficient showed very high (0.821) and high R2 (67,472%) dependence among variables both, in length of coleoptiles (as dependent variable) and mesocotyl (as independent) with low standard error (0.225). With the simple use of ultrasound the germination period could be shorten, water supply more efficient, the sowing periods will be shorten and good yields even under conditions of climate change with increased temperatures could be achieved.en
dc.description.abstractStudija istražuje efekat ultrazvuka na dužinu koleoptila i mezokotila kod klijanaca starih autohtonih sorata iz fam. Poaceae: ovas (Avena sativa L.) brodski, raž (Secale cereale L.) rakotinska, Triticale svetinikolsko i pšenica (Triticum aestivum L.) govrlevska. Tretmani su izvedeni sa frekvencijom od 30-40 kHz u termostatskom ultrazvučnom kupatilu na konstantnoj temperaturi od 25ºC u trajanju od 15 min. Ultrazvučni efekat se reflektuje na dužinu koleoptila i mezokotila, i pored toga što je njihov rast genetski predodređen. Najduži koleoptil je izmeren kod Triticale-a (3.3-5.5 cm) i približne dužine kod raži (3.0-6.1 cm). Najduži mezokotil razvija raž (5.525 cm ± 0.697). Veća dužina koleoptila u semena tretiranom ultrazvukom ukazuje na brži razvoj klijanaca, bolji vodni režim i brži razvoj i pojavu prvih listova. Korelacioni koeficijent je vrlo visok (0.821) kao i R2 (67,472%) što ukazuje na zavisnost varijabli dužina koleoptila (zavisna) i dužina mezokotila (nezavisna). Upotrebom ultrazvuka može se skratiti period klijanja, poboljšati vodni režim, a ranijim setvom dobiti zadovoljavajući prinosi i u uslovima globalnih klimatskih promena.sr
