Subject: Re: does drought stress make corn purple pics


Certainly some of the pioneer parent plants have this trait, but this year has been a little odd with brace roots trying to grow into hot dry soil and not getting it done. I have to think deep rooting is occurring in places where there is tile running (moisture is available), but it seems until the roots nearer to the surface straighten out, the plant may have problem with nutrient uptake. I see purple at the base of lots of plants (both P and D) and my hope is that the 3/4" rain and a little cool weather straightens things out a little.
