| Greenshoulder (GS) and Internal Greening (IG) are physiological disorders that threaten the processing carrot industry. This study examined the genotypic variations, the trigger, and the relationships between Leaf Area Index (LAI) and GS and IG, and certain agrotechnologies that could reduce the disorders. Genotypes differed in GS and IG. Increasing light intensity increased hypocotyl greening suggesting that light may act as a trigger. Canopy volume, measured as LAI, modulated GS and IG. FusiladeRTM, Linuron RTM and GesagardRTM did not trigger chlorophyll accumulation. Higher seeding rates, through its effects on LAI, reduced GS and IG. Three times hilling at early vegetative stage, initial bulking stage and final bulking stage reduced both GS and IG, possibly through etiolation effects. |
