article_snippet: The low intensity amber light was shown to prevent flowering in a wild relative of peas and beans called greater bird's foot trefoil, which is a key source of food for the pea aphid in grasslands and road verges, especially in mid-summer.
article_snippet: The study showed that low intensity amber light caused by street lighting in cities (a stock image of London at dusk is shown) prevented flowering in a wild relative of peas and beans called greater bird's foot trefoil, which is a key source of food for the pea aphid in grasslands and road verges, especially in mid summer .
