研究了茉莉酸甲酯（JA-Me）对郁金香（TulipagesnerianaL.）栽培变种Gudoshnik和阿佩尔多恩）在乙烯存在下进行了研究。茎和叶基部的胶形成由JA-Me（羊毛脂中的1%w/w）诱导，并通过同时应用1或5 mm 1-氨基环丙烷-1-羧酸（ACC）强烈刺激。0.1%浓度的JA-Me不诱导出胶，而与1或5 mmol/L的ACC共同诱导出胶。虽然JA-Me刺激乙烯生产基本上在茎完整的郁金香，乙烯利（1% w/w）或ACC（1或5毫米）没有诱导胶形成郁金香芽。JA-Me诱导郁金香芽中形成树胶，即使在存在的氨氧乙酸或钴离子。此外，在以浓度为0.23 mmol以上的JA-Me溶液施用的切枝中也观察到胶形成。这些结果强烈地表明JA-Me是郁金香芽中胶质形成所必需的，乙烯可能使芽组织对JA-Me敏感。
The promotive effect of methyl jasmonate (JA-Me) on the induction of gum in tulip shoots (Tulipa gesnerianaL. cvs. Gudoshnik and Apeldoorn) was studied in the presence of ethylene. Gum formation in the stem and the basal part of the leaves was induced by JA-Me (1% w/w in lanolin) and stimulated strongly by the simultaneous application of 1 or 5 mm1-aminocyclopropane-1-carboxylic acid (ACC). JA-Me at a concentration of 0.1% did not induce gum, but that together with ACC at a concentration of 1 or 5 mminduced it substantially. Although JA-Me stimulated ethylene production substantially in the stem of intact tulips, ethephon (1% w/w) or ACC (1 or 5 mm) did not induce gum formation in tulip shoots. JA-Me induced gum formation in tulip shoots even in the presence of aminooxyacetic acid or cobalt ions. Moreover, gum formation was also observed in the cut shoot applied with JA-Me as a solution at concentrations of 0.23 mmor more. These results strongly suggest that JA-Me is required for gum formation in tulip shoots, and ethylene probably makes the tissues of shoots sensitive to JA-Me.
