    摘要:

    为研究野生黄花型扁蓿豆分类归属问题,提供扁蓿豆物种鉴定和分属依据。对野生黄花型扁蓿豆(Medicago ruthenica L.)、扁蓿豆和黄花苜蓿(Medicago falcata L.)的花粉形态特征进行了观察和测量,比较三者之间的差异。结果表明,两种扁蓿豆和黄花苜蓿的花粉均属N3P4C5型单粒花粉,两种扁蓿豆花粉大小相近,均小于黄花苜蓿。但三者花粉外壁纹饰存在较大差异。黄花型扁蓿豆和扁蓿豆花粉表面具蜡质,黄花苜蓿花粉表面蜡质极少;黄花型扁蓿豆花粉外壁纹饰以穴状纹饰为主、伴有少量脑状纹饰,扁蓿豆花粉外壁纹饰整体为穴状纹饰,黄花苜蓿花粉外壁纹饰则整体为脑状纹饰。研究结果显示:黄花型扁蓿豆花粉外壁纹饰与扁蓿豆相近,与黄花苜蓿差异较明显,可作为扁蓿豆物种及不同种质的区分依据。

    Abstract:

    In order to distinguish different species of wild yellow type Medicago ruthenica, the pollen morphology of wild yellow type M. ruthenicaM. ruthenica and M.falcata were characterized and compared via microscopic observations. It showed that the pollens in wild yellow type M. ruthenic, M. ruthenica and M. falcata were all N3P4C5 type single granules. The pollen size of the two species of M. ruthenica were similar, which were smaller than M. falcate. There are significant differences on the pollen exine pattern among these three forage species. There are waxes covered on the pollen surface of yellow-flowered M. ruthenica and M. ruthenica, while it lacks of wax on the pollen surface of M. falcate. The pollen exine of yellow type M. ruthenica is mainly foveolate with slightly cerebroid-like pattern. The pollen exine of M. ruthenica is generally foveolate patterned, while that of M.falcata is generally cerebroid-like patterned. These results showed that the pollen exine pattern of yellow type M. ruthenica was most similar to M. ruthenica, but significantly different with M. falcata. Thus, the pollen exine pattern could be used as a morphological index for taxonomy of the germplams belonging to different species of M. ruthenica.
