Lilium tsingtauense is an endangered bulb plant in China that has curved leaves and orange flowers. Little is known about the opening of the L. tsingtauense flower. In this paper, the blooming process of L. tsingtauense flowers was sampled in five stages according to characteristic tepal morphology. The center of the tepal has an increasing elongation rate compared with the upper and lower parts. Tepal growth from closed buds at the greenish tepal stage (CBS) to the completely opened buds at the horizontal tepal stage is mainly due to cell division, cell elongation, and obvious longitudinal cellular growth. The fructose and glucose levels increased as the flower opened; however, the sucrose levels remained constant. |
