Do bees have a sixth sense? New research shows that opposites really do attract: bees are positively charged and flowers are negatively charged. Animal pollination occurs when plants bribe or trick animals into carrying their pollen to other plants of the same species. Here Dr. Mia Park, a pollination ecologist, explains how this this works.
PHOTO: Susan Pelton, UCONN Most milkweed species grow particularly well in disturbed areas, so start by looking in the following places: roadsides, pastures, along railroad tracks, bike paths, highway medians, agricultural field margins, vacant land, cultivated gardens, and parks. If you plan to grow your own milkweeds, or add milkweeds to your current site, you can collect seeds when the milkweed pods are ready to burst (this occurs in the fall in the northern U.S.). Once you have collected seeds, remove them from the pods and store them in an airtight container in a [...]
Cold stratification is the process of subjecting milkweed seeds to both cold and moist conditions as they require these conditions before germination will ensue. In the wild In the wild, seed dormancy is usually overcome by having its hard seed coat softened up by frost and weathering action during winter. This is nature's form of "cold stratification" or pretreatment. This cold moist period triggers the seed's embryo; its growth and expansion can then break through the softened seed coat in its search for sun and nutrients. Process In its most [...]
