But you can see how much the wheat has grown over the past month by clicking here . Let's look at the tillers. Here's a closeup of the tillers. You can see small and large tillers. We are still trying to find that first node or joint on the stem.
Some tillers are pretty big.
I think we should take a tiller and cut the stem with a knife to see if we can find the growing point. The stem has been cut and you can see the white area on the left is the root system. This stage is called the hollow stem stage . It is important for farmers to recognize this stage because if cattle are grazing the wheat, they should be removed from the wheat if it is going to be harvested for grain. Otherwise, if cattle continue to graze the wheat, the grain yields will be reduced.
