摘要: 以八千代、雨燕座、灿烂、特玉莲4种景天科多肉植物的正常植株与缀化植株为试验材料,研究了多肉植物的正常植株与缀化植株5种内源激素IAA、GA3、ABA、ZR、MeJA的含量差异及相关生理指标。研究结果表明,5种内源激素在正常植株与缀化植株中均有极显著差异,5种内源激素在正常植株与缀化植株中的含量基本表现为IAA>ABA>ZR>MeJA>GA3。多肉植物缀化后,5种内源激素含量变化基本表现为GA3含量上升,其他4种内源激素含量下降,其中ABA和ZR的含量变化情况具有一致性。生理指标测定结果表明,缀化后,景天科多肉植物的叶绿素含量均上升,可溶性糖含量及蛋白质含量因植物种类不同而表现为上升或下降。

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
