Corn Insufficiently Pollenated 



Each individual ovule must be Jertilized with the 



nucleus of a pollen grain. The so-called silk oj the corn 



consists oj thread-like pistils, each of which leads to an ovule. The 



pollen, produced in the tassel, sijts through the air in great 



quantities, but sometimes it Jails to reach all the threads 



of the corn silk. In that case a defective ear is 



produced as shown in this picture.
