Weíve had some warm days this past week. Temperatures were in the 90s twice and that has caused our wheat to turn colors. It is still green, but you can certainly tell that our variety, Jagger, has a bronze hue. Do you remember how green our wheat was in early May? Click here to compare May 9th with May 26th. We are losing flag leaves, but some are still holding on. However, they will not tolerate too many more hot days.
Hereís a closeup of a Jagger head. Note the streaks of bronze on the chaff. There are some interesting things happening in the spikelets, so if you want to see another closeup of this head click here.
|Hereís a closeup of a kernel developing in a floret (at the tip of the pointer). In this same spikelet you can see an aborted floret in the upper left. Do you see it? It is brown, but it isnít very big. Also, you can see the bronze streaks on the chaff. The chaff will get darker as the head matures.|
|What did you think the kernels would look like now? They are plump and theyíve lost that silverish-green color. Now they look more lime green to me. The lemma and palea stick to the kernel when you open the floret to look at it. These kernels are about 20 days old. (If you donít remember how these kernels have grown click here to see their development.) Okay, letís see whatís inside them now.|
|Well, they still have a milky substance, but it is thicker (almost like Elmerís glue without being sticky) and thereís more solid material inside the kernel. They are in the late milk stage.|
