EFFECTOF POTASSIUM IODIDE IN WHEAT (TRITICUMAESTIVUM L.)

摘要

The objective of this study was to determine the effect of irrigation/drought and potassium iodide applications on yield,some yield and quality components in wheat.This study was carried out in the location of Ataturk University Faculty of Agriculture,Erzurum,Turkey in 2004-2005 and 2005-2006 cropping seasons.Four bread wheat genotypes were used (Bezostaja-1,Karasu-90,Dogu-88 and Palandoken-97).Samples for determining minerals were taken at tillering period (Zadoks 20-29),flowering period (Zadoks 60-69),Three treatments (Irrigated,no irrigation and potassium iodide) were used.Seed weight per spike,seed yield,SPAD,test weight and thousand seed weight well responded to water supply,whereas protein and proline contents increased in water stress conditions.Similarly,irrigated treatment allowed increase in yield components that means growth conditions positive.Whereas,there are negative growth conditions in KI and no irrigation treatments.Bezostaja-1 and Karasu-90 were determined as the best genotypes in irrigated and stress conditions.Potassium iodide (KI) is more likely to be used in simulation of effect of water stress conditions on plant growth in irrigated conditions in breeding programs.
