Other claims from this paper (11)
- Intervention effect Simazine increased wheat nitrate concentration.
- Intervention effect Simazine decreased wheat glutamine synthetase activity.
- Intervention effect Autumn pesticide treatments did not affect wheat forage yield or protein content.
- Intervention effect Lower simazine rates applied at anthesis decreased wheat grain yields.
- Intervention effect Higher simazine rates at all three spring stages decreased wheat grain yields.
- Intervention effect Simazine treatments that reduced grain yield increased wheat grain protein concentration.
- Intervention effect Guthion applied in autumn increased wheat grain protein concentration.
- Intervention effect Other pesticide treatments had no effect on wheat protein or yield.
- Intervention effect Simazine at anthesis significantly decreased wheat grain test weights.
- Mechanism The authors attribute lower grain yield and higher protein concentration to detrimental photosynthate accumulation effects of simazine and no direct foliar effect on nitrogen assimilation.
- Mechanism The authors attribute decreased wheat grain test weight to floret sterility and undeveloped grains.
