Abstract:

The problems of bent stem caused by insufficient stem strength affect ornamental value and commodity price of ornamental plants to a certain extent. In this paper, the formation mechanism of ornamental plant stem was described based on their morphological characteristics, anatomical structure, physicochemical properties and molecular level. The regulation measures were summarized, which laid the foundation for the improvement of ornamental stem.

Key words: ornamental plants; stem strength; regulation
