Re: [Aroid-l] Blanching Query


Dear All,
 
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.
 
Bye,
 
Jani
