ＰＰＯＨ（顺式丙烯基膦酸）处理切花月季萨蔓莎品种，降低了乙烯生成量和盛开前的花茎增大率，增大了花朵开放直径；增加了盛开前花枝的鲜重，盛开期间保持了较高的吸水量与失水量比值；瓶插至盛开期和盛开持续期均显著延长。乙烯生物合成抑制剂ＡＯＡ（氨氧基醋酸）处理效果与ＰＰＯＨ相近，但因花朵“蓝变”使盛开持续期有所缩短。乙烯作用抑制剂ＳＴＳ（硫代硫酸银）处理增大了花径，显著延长了盛开持续期和瓶插寿命。ＰＰＯＨ和ＡＯＡ处理红衣主教品种，降低了乙烯生成量，ＳＴＳ处理则使之增加，但是都没有延缓开花和衰老的效果。推测ＰＰＯＨ延缓萨蔓莎开花和衰老是通过降低乙烯生成而起作用的。
PPOH (cis-Propylphosphonic acid) treatment cut rose Satsuma rose varieties, reducing the amount of ethylene production and flowering before the bloom increased, increasing the opening diameter of flowers; increased flowering before the bloom of fresh weight, holding in full bloom A higher water absorption and the ratio of water loss; bottle inserted in full bloom and in full bloom duration were significantly extended. Ethylene biosynthesis inhibitor AOA (aminooxyacetic acid) treatment effect and PPOH similar, but because of the flower “blue” so that the duration of bloom is shortened. Ethylene action inhibitor STS (silver thiosulfate) increased flower diameter, significantly prolonging bloom duration and vase life. PPOH and AOA deal with Cardinal varieties, reducing the ethylene production, STS treatment to make it increase, but did not delay the flowering and senescence effect. It is hypothesized that PPOH slows the flowering and senescence of Samantha by acting to reduce ethylene production.
