Abstract

Abstract: The palisade mesophyll and spongy mesophyll of cutter different riped leaf-position (lower,4th,cutter,10th,upper,16th) of Flue-cured Tobacco(K326 andHongDa) were divided by pectinase, then no-volatility organic acid was detected by gas chromatography, and plastid pigment or glucide or nicotine was analyzed by spectrophotometer. It showed that the content of multiple organic acid and nicotine of spongy mesophyll was higher than that of palisade mesophyll, and other components were on the contrary. No matter the palisade mesophyll or spongy mesophyll,the content of chlorophyllous in upper leaf cells was highest, and the content of no-volatility organic acid in lower leaf cells was highest, and the total content of carotin, glucide,deoxidize sugar in cutter leaf cells was highest, and the content of no-deoxidize sugar in cells hasn’t pertinence among the leaf position. The content of nicotine in cells was positive correlation with leaf position.

Key words: No-volatility organic acid, Plastid pigment, Glucide, Nicotine, Palisade mesophyll, Spongy mesophyll, Leaf position
