摘要: 通过形态解剖研究了杏黄兜兰花的发育过程, 发现杏黄兜兰5 月份发育出花序原基, 6~7 月份发育出花序鞘, 7~8 月份发育出苞片, 8 月底至9 月完成花器官形态分化过程。形态分化完成后杏黄兜兰的花器官继续快速增长。退化雄蕊、能育雄蕊、花柱在花形成后早期不融合, 在后期才融合形成合蕊柱, 且因为相对生长速率的不同, 三者的相对位置、形态也发生改变。此外, 在7~9 月份引种至昆明栽培的不同批次杏黄兜兰中, 产生花芽比率显著不同, 进一步证实8 月底至9 月初是杏黄兜兰进行花器官形态分化的关键时期。

Abstract: The development process of the flower of Paphiopedilum armeniacum was observed . It is found that P. armeniacum developed inflorescence primordium in May , then sheath in June and July, and bracts in July and August . All
organs of the flower were formed in late August and September. After the formation of the flower , the flower organs kept on growing and developing quickly . One sterile stamen ( staminode ), two fertile stamens and the style were not integrated at the early stages of the flower development , but fused to form the gynostemium in the late phase . Because of the different relative growth rate, the relative position and morphology of these three organs were different in the late phase. In addition, several batches of P. armeniacum were introduced to Kunming and cultivated in a greenhouse from July to September, the rate of plants with flower bud had significant difference in different batches, which further verified it is a key period for P. armeniacum to form the flower organs from the late August to the early September .
