Abstract:

In order to solve the problem of Thalictrum aquilegifolium var. sibiricum is not widely used in landscape because of the plant is very high and easily lodging, this article using different concentrations of CCC on vigorous growth of Thalictrum aquilegifolium var. sibiricum, by determining the height and stem diameter, length and other morphological indices and the content of chlorophyll and other related physiological indexes, studied the effect of CCC on growth of Thalictrum aquilegifolium var. sibiricum. The results showed that with the rising of the CCC concentration, the height displayed the "low-height-low" trend, and at 500 mg/L attain to the minimum. The content of chlorophyll showed upward trends and the activity of POD, SOD, CAT gradually increased. But when the concentration of CCC was larger, the margin of leaves turned yellow, scroll and other phenomena, affected the ornamental value. Comprehensively, the 500 mg/L of CCC concentration was better.
