Urban pollinators get the job done

12 febrero 2015

Native bees in San Francisco provide adequate pollination to crop plants such as tomato plants, new research shows. Plants left open to the air produced more and larger tomatoes than those that self-pollinated only, and even matched the production of artificially pollinated plants. The research also found that the density of flowers in a garden — and not the garden’s size — is the key factor in attracting more pollinators.
