Update on the Sonora Wheat we planted

A lot is going on, just below the surface.  Digging up a vigorous clump of Sonora revealed some impressive growth, with stems of 9-10 inches and roots up to 6 inches long.

                                                       CLUMP                                                             AFTER WASHING

This was on December 28th marking 29 days since we planted the seed, a period of both light and heavy rains, plus a number of nights when the temperature went below freezing.  
Almost all individual plants showed a first and a second fully emerged leaf.   Wheat plants typically produce 7 to 9 true leaves before the final flag leaf unfolds, revealing the developing seed head.

Many plants had a secondary stem emerging from the seed.

In all these instances, the remains of the coleoptile sheath that protected the first shoot can be seen, like a shedded snakeskin.
And quite a few plants had an additional growth emerging from beneath the sheath of the 1st leaf.  It is guessed that either of these growths could be tillers, although guides suggest that tillers begin to appear about when the 4th leaf emerges on the stem.      

Root structures are complex and subtle.  It is not clear whether we are seeing both the initial radicle and subsequent coronal roots.  But it is guessed that both are present 29 days after planting, with such vigorous growth.

      A lot is going on, with all of our wheat.  Some of the action is just out of sight.


  1. Paul, Thank you so much for your photos and analysis. Would you say that, on the whole, our grain is growing well? Is there anything in particular of which should be aware at this point? Mark

  2. Paul--I'll repeat what Mark said--THANK YOU! Nice job with the blog.
