自从1964年罗士韦首次报道田野兔丝子试管开花以来,迄今有关试管开花植物的报道越来越多,植物离体培养被认为是研究植物分化发育行之有效的手段(陈永宁,19881990、1991)。但从已有的报道来看,试管开花的植物种类多为一年生草本植物,多年生木本植物上的报道较少,外植体种类多为花芽、芽、茎、叶片、花瓣,薄层组织,原生质体等,种子作外植体少见报道。我们在工作中,首次发现了九里香试管播种实生苗能在播种后的一个月内开花现将有关现象作一初步报道。

Since the first report on the flowering of field rabbit silk tube in 1964, there have been more and more reports about flowering plants in vitro. In vitro plant culture is considered to be an effective method to study plant differentiation and development (Chen Yongning, 19881990, 1991). However, from the existing reports, most of the species of plants blooming in vitro are annual herbs and few on perennial woody plants. The explants are mostly flower buds, buds, stems, leaves, petals, thin layers, Protoplasts, seeds rarely reported as explants. At work, we first discovered that the nine seedlings of nine-seed-in-vitro test-tube planting can bloom within a month after sowing. This is a preliminary report on the phenomenon.
