The best condition for caretenoids stability are Neutral pH, hence increasing in pH decline the stability of caretenoids

Might be due to defllocultion of soil colloids due to higher concentration of exchangeable Na ions under higher pH condition which might have reduced surface area there by decreased uptake of all the necessary inputs like water and nutrients resulting in lesser production of chlorophyll and carotenoid

Research was conducted to determine effects of glyphosate [ N -(phosphonomethyl)glycine] on the chlorophyll and carotenoid and on the catalase specific activity in purple nutsedge (Cyperus rotundus L.). The isopropylamine salt of glyphosate caused chlorosis to appear on the center leaves of plants maintained under lighted conditions after treatment...
