AB  - In order to determine the effect of the number of grains infested with sunn pest (Eurygaster austriaca Schrk. and Emygaster maura L.) on the quality of wheat (Triticum aestivum L.), we analyzed five commercial varieties of bread wheat grown in field conditions in 2003/2004 on ten localities in Vojvodina, Republic of Serbia. A range from 0.8% to 8.26% of infested grains was registered on the analyzed sites. Reduction of quality traits (protein content - PC, sedimentation value - SV1, modified sedimentation value - SV2, wet gluten content - WG and energy test - E) was observed in accordance to the number of infested grains (damaged grain - DG). Statistically significant differences were determined in the number of damaged grains and analyzed quality traits between localities, varieties and their interaction (locality x variety). Although there was significant variation for the PC, WG and SV1 between localities, it was not as high as for SV2 and E. Obtained by modified Zeleny test, SV2 is considered to be an objective parameter for determining the infested grains. Results of this study indicated a different intensity of bug attack in researched localities. In addition, there was a different reaction of varieties to the wheat bugs bite, which may be used in plant breeding programs for the improvement of bread wheat resistance against attack of bugs.

AB  - This paper analyses chemical, rheological and physical changes on grains, flour, dough and baked bread made of wheat variety Prima, caused by delayed harvest due to large quantity of precipitation. Possible grain defects were evident in lighter washed-out colour of grain coat, decreased test weight from 82.3 kg hl-1 to 78.9 kg hl-1 and decreased falling number (FN) from 232 sec to 145 sec. Changes in dough were observed in lower viscosity on amylograph, from optimal 740 AJ to 285 AJ as a consequence of possible presence of α-amylase and increased amylolitic activity in endosperm. Physical changes on the grains of unharvested wheat in fields did not influence rheological properties of dough nor the quality of baked product. Quality of bread made from wheat grain from delayed harvest was better than quality of bread made from wheat harvested are the beginning of harvest season.
AB  - Analizirane su hemijske, reološke i fizičke promene na zrnu, brašnu, testu i gotovom hlebu od sorte pšenice Prima, izazvane odlaganjem žetve zbog velikih količina padavina. Eventualna oštećenja zrna su registrovana svetlijom izbeljenom bojom omotača zrna, smanjenom hektolitarskom masom sa 82,3 na 78,9 kg hl-1 i smanjenim brojem padanja (FN) sa 232 na 145 sec. Promene na testu registrovane su smanjenjem viskoziteta na amilografu, sa optimalnog 740 na 285 AJ kao posledica eventualno prisutne α-amilaze i povećanja amilolitičke aktivnosti u endospermu. Fizičke promene na zrnu nepožnjevene pšenice u polju nisu uticale na reološka svojstva testa i kvalitet gotovog proizvoda. Kvalitet hleba napravljen od zrna pšenice iz produžene žetve bio je bolji nego od zrna požnjevenog na početku žetve.

AB  - Amylolytic activity in 15 winter wheat cultivars has been followed by a comparative analysis of the values of peak viscosity on Brabender Amylograph (BU) and the values of falling number (FN) according to Hagberg (sec). Only one cultivar, Renesansa, had the peak viscosity below 500 BU and the FN below 250 sec. Four cultivars had the peak viscosity between 500 and 800 BU, seven cultivars between 800 and 1500 BU and three cultivars above 1500 BU. Twelve cultivars had the FN between 250 and 300 sec and only two above 300sec. The obtained values were compared against the values of bread made from the flour of these varieties. Bread quality was assessed as baking score (BS) via crumb quality, the parameter that represents the numerical expression of crumb elasticity and pore structure fineness.
