With the wheat moving through heading as quickly as it has, I thought I’d better ignore the rain and look at our area today. We’ve had nearly 1 inch of rain since yesterday afternoon and it is still sputtering rain. Here’s a general view of our area. The flags are being covered again. The wheat in our area is very uneven in height. That’s because of the Barley Yellow Dwarf, which stunts the plants’ growth and the fact that this field is for seed production and we used a much lower than normal seeding rate last fall at planting. |
|
As you can see from a closeup of our row, most of the wheat is either headed or almost headed (The head has emerged completely from the boot.) You can still see the yellow leaf tips, a classic symptom of Barley Yellow Dwarf. |
|
These are the two most advanced heads that I could find in our area.
Notice they both have emerged from the boot, but the one on the right is taller. "Why
is that?" you ask. The stem or peduncle is elongating and that raises the head
further away from the flag leaf. If you want to see the early stages of heading, you can
go to the April 26th date to see the boot stage and early head emergence.
(Because it was cloudy and raining when this picture was taken, I took
another picture when it was sunny– click
here to see the new picture) Where are the kernels? Patience, patience. After a head is fully emerged it will begin flowering within 3-5 days, so we should see the flowering stage by the end of the week. And after flowering it will be several days before we can see a kernel. |
