Abstract:The quality of flue-cured tobacco leaves on different soil textures was different. Exploring the difference of aerial parts dynamic growth could help to raise and perfect the basis of flue-cured tobacco cultivation measures under different soil texture conditions. Sandy soil, clay soil and loam soil were selected for the experiment with flue-cured tobacco breed NC89 in 2012. The results showed that the quality of flue-cured tobacco leaves was the best in sandy soil, while poor in clay soil. For sandy soil, the flue-cured tobacco plants were much taller, and its stem girth and dry weight (DW) were smaller. Though its DW and starch accumulation rate were lower, the accumulated time was longer in sandy soil, which contributed to the significantly higher of pigment content and the lower of pigment degradation rate comparing with the other two treatments. For loam soil, the DW and starch content were higher, and the DW accumulation rate was higher, but the starch accumulation rate was higher only in early growth stage. For clay soil, the pigment content in early growth stage was higher, but the degradation rate was also fast. As a result, the pigment content was lower and the starch content significantly higher than the other two treatments in mature stage. Under the premise of flue-cured tobacco plant height within 120 cm, and stem girth within 12 cm, the DW and starch accumulation rate are lower, but they accumulated for a long time. Meanwhile, the little higher content of pigment, the better quality of tobacco leaves.
