| Abstract: | Variation in falling number, amylase activities, protein concentration and composition were investigated in two wheat cultivars
grown in Sweden over two seasons, in four locations, with four N fertilizer rates, with and without fungicide treatment. The
results showed that;
| •
|
Tarso had higher falling number, amylase activities, protein concentration and amount of most protein components compared
to Kosack.
|
| •
|
The environment (year, location, N rate and fungicide treatment) influenced falling number, alpha amylase activities, and
protein concentration and composition.
|
| •
|
Two processes were related to low falling numbers; late maturity leading to poor starch and protein quality and excessive
rains leading to break-down of starch and proteins.
|
| •
|
Poor starch and protein properties influenced the bread-making quality to a higher extent than break-down of starch and proteins.
