Effects of Suni Bug (Eurygaster spp.) Damage on Milling Properties and Semolina Quality of Durum Wheats (Triticum durum L.)

Hamit Koksel; Tulin Ozderen; Burcu Olanca; et al. Cereal Chemistry 2009. doi:10.1094/cchem-86-2-0181

Other claims from this paper (7)

Intervention effect Semolina yield of durum wheat cultivars decreased significantly as suni-bug damage level increased.
Intervention effect The loss of semolina yield was greater than the decrease in total yield of semolina plus flour under suni-bug damage.
Intervention effect Ash content of semolina increased significantly in all cultivars with increasing suni-bug damage.
Association Falling number values were not correlated with suni-bug damage level.
Observation Amylase activities of durum wheat semolina samples were quite low.
Intervention effect Pasting properties of durum wheat semolina did not differ to a great extent depending on suni-bug damage level.
Intervention effect Gluten quality of durum wheat semolina deteriorated substantially as suni-bug damage level increased.

Other claims from this paper (12)

Intervention effect Caustis showed P toxicity symptoms at P application rates above 11 g P per m3 medium as MCP.
Observation Caustis did not show deficiency symptoms at no added P.
Observation The critical P concentration in the plant tops associated with a 10% decrease in yield from the maximum was 0.33% for Caustis 'B84'.
Intervention effect The two Caustis cultivars did not develop P toxicity symptoms or show any decline in tops dry weight when fertilised with RP.
Association For Caustis 'M63' fertilised with MCP, the severity of P toxicity increased as the P adsorption capacity of the growth substrate decreased (Palmwoods soil > Mt Cotton soil > potting medium).
Intervention effect Waxflower grown under non-leaching conditions showed reduced tops weight at no added P or when fertilised with RP.
Observation The external P requirement for 90% of the maximum tops dry weight of waxflower was estimated at 110 g P per m3 medium when P was applied as MCP.
Intervention effect Waxflower did not develop P toxicity symptoms even at 352 g P per m3 medium.
Intervention effect Sticherus did not respond significantly to P applied as MCP or RP.
Intervention effect Sticherus grew much better under leaching conditions than under non-leaching conditions.
Intervention effect Leaching reduced P toxicity in Caustis.
Intervention effect Leaching caused a considerable loss of P and other nutrients.
