[1] In fruit trees, bees are an essential part of the pollination process for the formation of fruit. [2] Pollination of fruit trees around the world has been highly studied for hundreds of years. [1] Much ...
The Callery pear, or Bradford pear, is one of those vampires. Over the years, Callery pear (Pyrus calleryana) has become one of the most widely planted ornamental trees in the US. But over that ...
