A short while back I explained how some recent rain and winds had knocked down some sweet corn. That's not a good thing when the corn is about to tassel. If the pollen doesn't fall on the silk, you'll have "blank heads." I made a redneck sweet corn propper-upper with t-posts and baling twine and the effort was met with success. The corn is standing tall once again in our two-row corn plot.
Let's look at a couple of zoomed in photos of the sweet corn tassel. Although you'd never know it, the tassel is the male reproductive organ. It produces pollen.
If I had zoomed in on the following two photos, you'd be able to see the yellow pollen.
As the wind blows, the pollen drifts in the air, falling (hopefully) on the silk sticking out of the ears. Each one of those silk threads shown below, goes into the corn cob and where it's attached to the cob, a kernel of corn will come to be. Pollination done by the wind uses gravity too, and that's why it was critical that I stood the corn upright before corn tasseled. If you ever shucked an ear of corn and the ear had a bunch of gaps in it, you didn't get good pollination. It's another reason it is a good idea to plant your corn in blocks and planted close together. We're not going to count our chickens before they hatch, but it looks pretty good so far.
