Abstract:The anatomical structure of leaf of Oriental Tobacco was investiga-ted by tissue sectionary;the result was as follows:Glandular hair of matureleaf secreted largely and the head was biggest.During mature process,theplasma of mesophyll cell concentrated gradually near the cell wall and at lastthe cell centre got empty;the cell nucleus got smaller and almost disapperedin time of leaf overripe;the granular sugar content of cell was also gettingsmaller.As the stalk position rose,all the thickness of leaf,palisade paren-chyma and sponge parenchyma appeared in a form of concave curve.Duringmature process,the mesophyll cell's structure change got slower,the densityof epidermis stoma and the granular sugar content of cell increased.The tab-acco grew weakly,plasma of mesophyll dell became less and the leaf appearedoverripe easily in big cultivated density(11000 plant/mu);cultured in smalldensity(5400 plant/mu),the tabacco grew luxuriantly,plasma of mesophyllcell was thick,the leaf was not easy to mature;in proper cultivated density(6600 plant/mu),the tabacco grew normally,the leaf could mature ontime.
Keywords:oriental tabacco  maturity  stalk position  glandular hair  mesophyll cell leaf thickness  cultivated density
