The Endogenous Plant Hormone Profiles of the Flower Parts of Melon

抄録

We explained the phytohormone profiles associated with the various stages of the parts of melon reproductive organ growth. This study was achieved using melon flowers that were obtained 0 to 7 days before flowering (DBF), after which their parts were divided into the sepals, petals, stamen and pistil. Then, we quantified simultaneously indole-3-acetic acid (IAA), abscisic acid (ABA), trans-zeatin (tZ), isopentenyladenine (iP), jasmonic acid (JA), methyl jasmonate (MeJA), gibberellin₁ (GA₁) and gibberellin₄ (GA₄). The IAA concentration increased rapidly at 0 DBF in the stamen. Likewise, the tZ, iP, GA₁, GA₄ and MeJA in the stamen had the highest concentration among the four parts. In contrast, ABA, JA, and MeJA concentrations in the petal decreased from 0 to 7 DBF.
