摘 要 ：以网纹甜瓜(Cucumis melo L.var. reticulatus Naud.)品种’西域1号’为试验材料，于幼苗3叶1心期喷施浓度为150 mg·L^-1的乙烯利溶液进行处理，诱导主蔓形成两性花，以清水为对照，分别对处理和对照植株不同时期的主蔓和侧蔓花芽分化过程进行形态和解剖学观察。结果表明：经乙烯利处理后，幼苗植株主蔓花原基持续向两性花分化，最终发育形成两性花。未经处理植株的主蔓花原基在分化早期与两性花发育过程相同，但在雌蕊出现后，不再继续发育，最终发育形成雄花。处理植株主蔓两性花发育过程与侧蔓两性花发育过程相同。

Abstract:The muskmelon (Cucumis melo L.var. reticulatus Naud.) varity ‘Xi Yu No.1’ was treated with 150 mg·L^-1 ethephon at appearance of the fourth euphylis，in this study in order to induce the formation of bisexual flowers in main vine，materials treated with fresh water was used as control. The flower buds were extracted from main and lateral vine of control and treated seedlings at different stages，then their differentiation processes were observed from morphological and anatomical viewpoints. The results showed that the flower primordium in main vine of seedlings，which were treated with ethephon differentiated into bisexual flower sustainably and formed bisexual flower at last. The flower primordium in main vine of untreated seedlings had the same differentiation process with bisexual flowers at early stage. After the appearance of pistill development was stopped and male flowes were finally formed. The development process of bisexual flowers in main vine of treated seedlings was the same as the bisexual flowers in lateral vine.
