Propionic acid (10(-3)m) increases ethylene production by about 30 to 60% in tissue from green and half-ripe tomatoes (Lycopersicon esculentum Mill. var. Homestead) but does not increase ethylene production in tissue from ripe fruit. Stimulation is not due to the conversion of propionic acid to ethylene but appears to be secondary in nature and to operate on the endogenous ethylene-forming system. Thus conversion of methionine to ethylene in green and half-ripe tomato tissue is increased in the presence of propionic acid. Inhibitors which affect the normal endogenous ethylene-forming system similarly affect the propionic acid-stimulated system. Endogenous propionic acid may play a role in the regulation of ethylene production in tomato tissues.
丙酸（10(-3)m）使绿熟和半熟番茄（Lycopersicon esculentum Mill. var. Homestead）组织中乙烯的产量增加约 30%至 60%，但不增加成熟果实组织中乙烯的产量。这种刺激不是由于丙酸转化为乙烯，而是自然的次级作用，并作用于内源性乙烯形成系统。因此，在丙酸存在的情况下，绿熟和半熟番茄组织中天冬氨酸向乙烯的转化增加。影响正常内源性乙烯形成系统的抑制剂也同样影响丙酸刺激系统。内源性丙酸可能在番茄组织中乙烯产生的调节中发挥作用。
