Pollination Corn Silks Explore the timeline for corn pollination and how to determine successful ovule fertilization. Silk detachment confirms successful fertilization of the corn embryo and occurs on the second day after pollination of exposed silks. it takes quite a bit of time to harvest an ear, carefully peel back the husks, and gently shake the ear to estimate the number of detached silks.
Pollination Corn Silks Normally, pollination is a continuous process with fertilization occurring gradually along the ear as silks emerge. a mass of long, green silks is an indication that pollination has not occurred (figure 5). Each silk connects to an individual ovule (potential kernel). a given silk must be pollinated in order for the ovule to be fertilized and develop into a kernel. up to 1000 ovules typically form per ear, even though typically only 400 to 600 actual kernels per ear survive until harvest. What are corn silks, and what do they do? each strand connects to a single kernel and plays a key role in how corn is pollinated and grown. Each potential kernel on an ear is connected to a single strand called a silk. these silks emerge from the tip of the ear and are fine, sticky hairs. the physical separation of the tassel and the ear, along with the distinct roles of these structures, are fundamental to corn’s pollination strategy.

Specialized strands known as silks emerge from the tip of the ear shoot. each silk strand is directly connected to a single ovule, which is the potential kernel. for an ovule to develop into a mature kernel, its corresponding silk must be successfully pollinated. The first silks will emerge about 3 days after pollen shed begins. silking is delayed more than tasseling when the corn plant is under moisture stress. under extreme drought conditions, the silks grow slowly and may not emerge from the husks before the pollen is shed. If dark, curled up silks fall out, it's a good indication that corn pollination has taken place. when corn has been pollinated, the silks dry up, turn brownish in color and can fall off.
