通过观察比较,研究了火柴头生殖器官的多样性。火柴头有3类生殖枝、5种花、6类种子。气生生殖枝负向地性生长,贴地生殖枝和地下生殖枝是茎基侧芽向地性生长形成的。地表生殖枝和地下生殖枝无叶片,地下生殖枝不具光合色素,3种生殖枝上都能着生花苞。5种花是开花传粉型雄花、开花传粉型两性花、闭花传粉型两性花、贴地生的闭花传粉型两性花与地下闭花传粉型两性花,5种类型花的花部亦呈多样性。6类种子是地上大、中、小种和地下大、中、小种,不同种子的形态特征不同。
By observing and comparing, we studied the diversity of match-head reproductive organs. There are 3 kinds of matchwood head, 5 kinds of flowers, 6 kinds of seeds. Gypsophila gynostemma negatively growth, affixed to reproductive branches and underground reproductive branches are stem-based lateral bud to the formation of growth. Surface reproductive branches and underground reproductive branches without leaves, underground reproductive branches not photosynthetic pigment, 3 kinds of reproductive branches can be born with buds. Five species of flowers are flowering pollen-type male flowers, flowering pollen-type bisexual flowers, flowers closed pollination bisexual flowers, paste the ground-breaking pollination bisexual flowers and underground flowers pollination bisexual flowers, flowers of the five types of flowers are also diverse Sex. Six kinds of seeds are large, medium and small species and underground large, medium and small species, different seeds of different morphological characteristics.
