Abstract:

In order to explore the use of artificial methods to reshape landscape type Taxus chinensis var. mairei. The morphologyical characters and ornamental traits of landscape type Taxus chinensis var. mairei. under different artificial light environment were studied in Mingxi, Fujia. The author analyzed and compared plant height, ground diameter, CFR, the foliage dense degree, lateral branch germination. The results showed that: morphologyical characters and ornamental traits were modified plastically in response to different artificial light conditions. The full sunlight condition than the long-term shade condition significantly increased CFR, the foliage dense degree, the number and the average length of the 2,3-order lateral branches, the overall branching rate; the long-term shade condition than the full sunlight condition significantly increased plant height, ground diameter, the first-order lateral branch germination, leaves significantly more dark green, but significantly reduced first-order lateral branch length. These indicated that: Taxus chinensis var. mairei. made some necessary changes in morphological aspects in order to accommodate it to the change of light environment. Anthropogenic changes plant growth light environment could change plant morphology, was an important measure of artificial reshaping landscape type Taxus chinensis var. mairei.
