Abstract:
In this paper, height, ground diameter and stem form between tissue-culture plantlets and seedlings of Pinus elliottii were compared. Differences of growth traits among different families and clones were found. The height of seedlings were significantly higher those of plantlets. Seedlings of common family grow fasters than those of disease resistant family. However, little difference found within 8# and 32# disease resistant family. Both seedlings and tissue-culture plantlets severely grow in an oblique way. The generation of the plantlets affects little to the growth of height and ground diameter. Positive correlation occurred between the plantlets age and the plantlets height. Different clones of 8# had significantdifference of height, however little difference was found in ground diameter.
