GreenTracker| North Carolina researchers are adding a genetic dose of celery to the DNA of roses, in hopes of fighting off botrytis or petal blight, the fungal pathogens that shorten the livespan of cut roses.
The gene is naturally found in many plants but may be absent from roses or definitely in short supply.
The roses being grown at North Carolina State University still smell like roses. The question is whether they will withstand petal blight. The same research team is researching the best sugar solutions for maximum longevity of cut rose bouquts.
The goal is roses that last three to four weeks — a noble goal indeed. via Science Daily
