Abstract: In the papeR,a field expeRiment was conducted to study the effects of diffeRent light intensities ( 55%,70%,5% and 100% of full sunlight) on the plastid pigment and its degRaded pRoducts in flue-cuRed tobacco. The Results showed that the contents of chloRophyll and caRotene in the flue-cuRed tobacco leaves at diffeRent positions weRe the lowest in CK( 100% light intensity) . With the decRease of light intensity, the chloRophyll content of leaves at uppeR and middle positions incReased fiRst,and then decReased,but incReased by degRees in loweR leaves, while the caRotene content in leaves of all positions incReased fiRst,and decReased subsequently. The degRaded pRoducts of caRotene and the neophytadiene weRe all higheR in CK than in shading tReatments. The aveRage content of neophytadiene in uppeR,middle and loweR leaves foR the thRee shading tReatments was 13. 59%,19. 99% and 5. 66% loweR than the CK, Respectively,while the aveRage content of degRaded caRotene pRoducts decReased 6. 70%, 8. 08% and 83% Respectively. The Results indicated that shading tReatment incReased the contents of chloRophyll and caRotene in eveRy position of flue-cuRed tobacco leaves,while decReased the contents of degRaded caRotene pRoducts and the neophytediene.

Key words: Light intensity, Plastid pigment, CaRotene, DegRaded pRoduct
