| Research Abstract |
The apomictic seed of mangosteen fruit is formedat relatively late stages after anthesis and derive from the inner layer of integument as a cell mass not as a nucellar embryo. Furthermore, despite that mangosteen fruit has 4-7 locules, only 1-3 locules develop well without pollination and these well developed-locules are filled with the liquid of endosperm. So, we speculated an important role of plant hormones in the liquid for apomictic seed development and have tried to analyze plant hormones in this liquid by GC-MS. As a result, we identified IAA, ABA and jasmonic acid, and the fluctuation of these hormone contents during fruit development is determined for considering a role for apomictic seed formation. In addition, the external treatments of these plant hormones didn't show a relationship to apomictic seed formation, indicating the improvement for treatment methods.
