根瘤菌毒素类似物L-2-氨基-4-（2-氨基乙氧基）-反式-3-丁烯酸和苯甲酸钠抑制香石竹（Dianthuscaryophyllus，L. CV.白色西姆），并延长了几天的花瓶寿命。将根瘤菌毒素类似物（Ro）和苯甲酸钠加入到2%蔗糖、0.02%8-羟基喹啉柠檬酸盐和0.02M柠檬酸钾缓冲液（pH 4.7）的基础保持溶液中。结果表明，0.068 mM的Ro使切花康乃馨的瓶插寿命增加了95%或更多。1.0或2.0 mM的苯甲酸钠也增加了瓶插寿命。这些化合物可能通过抑制乙烯的产生而增加了花的瓶插寿命。这些化合物的作用超过蔗糖、8-羟基喹啉柠檬酸盐和保持溶液的酸性pH值的作用。
The rhizobitoxine analog, L-2-amino-4-(2-aminoethoxy)-trans-3-butenoic acid, and sodium benzoate inhibited ethylene production in cut flowers of carnation (Dianthus caryophyllus, L. cv. White Sim) and extended the vase life by several days. The rhizobitoxine analog (Ro) and sodium benzoate were added to a basal holding solution of 2% sucrose, 0.02% 8-hydroxyquinoline citrate, and 0.02 M potassium citrate buffer (pH 4.7). The results indicate that Ro at 0.068 mM increased the vase life of cut carnations by 95% or more. Sodium benzoate at 1.0 or 2.0 mM also increased the vase life. The compounds may have increased vase life of the flowers by inhibiting ethylene production. The effects of these compounds were over and above the effects of sucrose, 8-hydroxyquinoline citrate, and acid pH of the holding solution.
