Abstract:

Shading cultivation is one of the main methods for the production of high-quality cigar wrapper leaves. Light intensity is one of the most obvious changeable factors under shading cultivation conditions. This review summarizes the research progress of changes and their mechanisms of tobacco leaves under different light intensity due to different shading conditions. In view of the problems and deficiencies in the current research on the shading production of cigar wrapper leaves, it is pointed out that on the basis of improving the quality evaluation system of cigar wrapper leaves, the effects of shading on the quality of the appearance, physics, chemistry, and sensory aspects of cigar wrapper leaves should be studied in depth. And the shading production system suitable for the varieties and the actual production area should be further explored, realizing the effective supply of domestic cigar wrapper leaves gradually.

Key words: shading, light intensity, cigar wrapper leaves, growth characteristics, chemical constituents, sensory quality, photosynthesis
