Using fluorescence microscopy, we are able to see individual pollen tubes entering the ovules within the pistils of flowers. To the left is an example of two pollen tubes entering two ovules from a crossing treatment. Pollen from one population was used to pollinate the stigmas of flowers from a second population. The micropyle where the pollen tubes enter the ovule is too small to be seen, but it is located to the right side of the ovule.
While spending the holidays in Philadelphia with family I had the opportunity to visit Longwood Gardens, which is located 30 miles west of Philly near Kennett Square, PA. Longwood Gardens is a leader in public horticulture, defined by the Center of Public Horticulture at the University of Delaware as "...the art and science of cultivating plants in spaces for public use and enrichment." Longwood Gardens consists over 1,000 acres of beautifully maintained grounds, and includes a spectacular, extensive indoor conservatory. One of the highlights this year was a display of 18,000 floating apples!
