Sažetak
U cilju procene odnosa između prinosa i nekih relevantnih osobina i procene osobina koje najviše utiču na prinos zrna, sproveden je eksperiment sa podeljenim parcelama zasnovan na potpuno slučajnom blok sistemu sa četiri ponavljanja tokom 2006-2007. godine na istraživačkom polju Islamskog slobodnog univerziteta u Karadžu. Sheme navodjavanja planirane kao glavne parcele su uključivale sledeće tretmane: (T1) 40% smanjenje vlage tokom vegetacione sezone (kontrola); (T2) 60% smanjenje vlage tokom vegetacione sezone; (T3) 80% smanjenje vlage tokom vegetacione sezone; (T4) bez navodnjavanja u fazi intenzivnog porasta stabla i nastavljenje adekvatnog navodnjavanja do kraja sezone; (T5) bez navodnjavanja od faze intenzivnog porasta stabla do kraja vegetacione sezone; (T6) bez navodnjavanja u fazi cvetanja i nastavljanje sa adekvatnim navodnjavanjem do kraja sezone; (T7) bez navodnjavanja od faze cvetanja do kraja vegatacione sezone; i (T8) bez navodnjavanja od faze mlečnog zrenja do kraja sezone; i dve sorte pšenice [Marvdasht (V1), Chamran (V2)] kao potparcele. Prema rezultatima jednostruke korelacije, prinos zrna je bio u pozitivnoj korelaciji sa biomasom (0,877), brojem infertilnih klasića (0,876) i žetvenim indeksom (0,855). Rezultati delimične regresije su pokazali da, u odsustvu stresa izazvanog sušom, biomasa odnosno žetveni indeks imaju najvažnije uticaje na prinos zrna, ali da su oba pokazala različite rezultate u uslovima stresa izazvanog sušom. Rezultati path analize su pokazali da je najvažniji uticaj na prinos zrna kod svih proučavanih tretmana povezan sa biomasom, opravdavajući ukupno 87% varijacija prinosa zrna, od čega 72% predstavlja direktan uticaj ove osobine na prinos zrna.
