Re: [Aroid-l] Blanching Query
We laerned, that some of the herbicides are destructing the
pigments or stop their biosinthesis.
Some of them are destructing the chlorophylls (ABC), but some
of them destructing carotionoids as Carotine, Xantophyl. The carotionoids main
profit is that they are collecting the harmful or too much sunlight (foton) so
the chlorophylls can work as they should.
If you spray plants with carotinoid destructing herbicides in
one or two days they seem to be sunburned, and they die in it, becouse the
harmful waves (e.g. UV) destroy the chlorophylls. So if your plant is sunburnt
(and not sprayed with herbicide by one of your "favourite" neighbour) the
carotinoids are not sufficient in the leaves and stems, than the
chlorophyll is destructed too.
