| 摘 要： | 以探讨月季切花不同花器官的乙烯生物合成和对乙烯的感受为目的，以切花月季‘Samantha’为试材，进行了乙烯和1-MCP交叉处理，测定花朵各器官乙烯生成量，Rh-ACS3、Rh-ACO1和Rh-ETR3基因的表达。结果表明，1-MCP前处理或后处理均能有效抑制花瓣、雌蕊和花托中由于外源乙烯造成的内源乙烯生成量增加。在基因表达方面，Rh-ACS3、Rh-ACO1和Rh-ETR3在花瓣和雌蕊中对乙烯处理的诱导表达均可被1-MCP前处理或后处理有效抑制，而在花托中，这种抑制主要针对Rh-ETR3。这些结果说明，1-MCP对乙烯的竞争性抑制作用主要发生在花瓣、雌蕊和花托上，其竞争效果在乙烯处理前或乙烯处理后均有效。

| Abstract: | The effects of ethylene and its inhibitor，1-methylcyclopropene（1-MCP）treatments on the flower opening，ethylene production，and the expression of ethylene biosynthesis- and perception-related genes in cut rose‘Samantha’were investigated. The results showed that 1-MCP pre-treatment or post-treatment substantially inhibited ethylene-caused increase of ethylene production in petals，gynoecia，and receptacles. 1-MCP treatments also substantially inhibited the expression of Rh-ACS3，Rh-ACO1 and Rh-ETR3 genes in petals and gynoecia，but of only Rh-ETR3 in receptacles. The results indicated that the effect of competitive inhibition of 1-MCP on ethylene occurred mainly in petals，gynoecia and receptacles，and the effect was substantial，regardless the treatment was performed before or after ethylene treatment. |
