Abstract

Abstract: The normal plants and embellished plants of four species of succulent plants in Crassulaceae, Yachiyo, Swift, Splendid and Te Yulian, were used as experimental materials to study the content differences and related physiological indicators of five endogenous hormones IAA, GA₃, ABA, ZR and MeJA of normal and embellished plants of succulents. The results showed that the five endogenous hormones were significantly different between normal plants and embellished plants. The content of five endogenous hormones in normal plants and conjugated plants was basically IAA>ABA>ZR>MeJA>GA₃. After embellished, the changes of five endogenous hormones showed that GA₃ content increased, and the other four endogenous hormones decreased. The changes of ABA and ZR content were consistent. The results of physiological indicators showed that after embellishment, the chlorophyll content of succulent plants in Crassulaceae increased, and the soluble sugar content and protein content increased or decreased depending on the plant species.

Key words: succulent plants in Crassulaceae, embellishment, endogenous hormones, physiological indicators
