Re: Re: pollinators

I don't think that pollinators is the sole reason for cord grass to have poor
seed production.  If this were the case, then the grass would send up many
bolts, but the seed would not get fertilized and therefore would be sterile.
 

In my casual observation and others, it seems like cord grass produces more
seed head when slightly stressed.  Cord grass is such a colonial plant that
once it gets established in an area it is content to remain the dominant in
that area and not spread out too much.  It seems as though when the plant is
slightly stressed, it will produce more seed heads.  

We find cord grass in road ditches a lot around here, and the areas that have
the heaviest concentration of seed heads tend to be bordering corn or soybean
fields rather than pastures or vacant land that was not worked up that year.

Germination tests done on cord grass show that it has a fairly low percent of
viable seed out of the seed produced by a plant.  This discrepency could be
accounted for by a lack of pollinators.
