Pollutant causes delayed flowering in plants
...itric oxide emitted as air pollutants from burning fossil
fuels could affect the critical process of plant flowering. Since the decision to flower is so critical to reproduction, a delay in flowering could have important impacts on ecosystems, both plant and animal, they said. The researchers, led by Duke U...
