Florida researchers try to put scent back into flowers

If you are among the millions who receive flowers on Valentine’s Day, you likely will put your nose to a rose, only to find you can’t catch a whiff of your favorite floral aroma. And it isn’t because your sense of smell has diminished. Plant breeding has led to bigger, longer-lasting blooms, but in the process many flowers have lost their scents – a trend University of Florida researchers hope to reverse. The researchers are investigating ways to put scent back in, either through genetic engineering or by developing chemical formulations that might be used through a spray application.
