Anatomical characteristics of dwarf Cunninghamia lanceolata

    Corresponding author: TONG Zai-kang

Abstract: To reveal how dwarfing occurs with Cunninghamia lanceolata(Chinese fir),and clarify the internal structure of both branch and leaf,the anatomical characteristics of a dwarf and a control(a normal tree) were compared with the method of manufacture slice in 2007 and using t-test. Results revealed that the average growth of the trunk (25.54 cm) and branches (24.59 cm) of the dwarf were significantly(P<0.01) lower than the control (trunk:89.61 cm and branches:57.52 cm). Furthermore,for the bark,the dwarf average was 76.50%,and the control was 37.70%(P<0.01). The average mean area of a tracheid cell for the dwarf (241.901 6 μm2) was significantly(P<0.01) lower than the control (308.894 6 μm2),however,the average dwarf tracheid density was 3 375 cells·mm -2,whereas the control was significantly(P<0.01) lower at 2 456 cells·mm -2. For leaf unit length,the dwarf average (trunk:14 leaves·cm -1 and branches:10 leaves·cm -1) were significantly(P<0.01) greater than the control (trunk or branches:7 leaves·cm -1);however,there were no difference in the proportion of palisade tissue and spongy tissue.
