The palisade tissue cells of common type were 2 layers, while those of spur-type and columnar type were 3 or 4 layers. The ratio of palisade tissue and spongy tissue of common type was less than 1, and that of spur type and columnar type was more than 1. Moreover, the number of palisade tissue cell layers and the ratio of P/S were increased with the dwarfing degrees.
