| 摘 要： | 利用常规石蜡制片法,对甜菜单体附加系M14(Beta vulgarisL.VV 1C、2n=18 1)雌配子体的发生与发育进行了研究,结果表明:二倍体孢子生殖雌配子体为韭型(Allium odorum-type)和蝶须型(Antennaria-type),有性生殖雌配子体为蓼型(Polygonum-type)。韭型和蝶须型的大孢子母细胞发育成为二倍体雌配子体,蓼型大孢子母细胞形成单倍体的雌配子体。在二倍体孢子生殖雌配子体发育过程中,出现发育迟缓,胚囊败育等情况,正常发育的雌配子体只有25%。讨论了二倍体孢子生殖雌配子体发生与发育特点。 |

| Abstract: | The megasporogenesis and development of female gametophyte were studied by paraffin sections in line M14,a chromosome 9 monosomic addition line of Beta corolliflora Zoss.in sugar beet,in which revealed that the egg cell could been produced through diplospory or sexuality.The results are as follows:sexuality is of Polygonum-type,and diplospory is of two types,Allium odorum-type and Antennatia-type in M14.The megasporocyte of Allium odorum-type and Antennatia-type turn into a mature diplosporous female gametophyte.The Megasporocyte Polygonum-type turns into a mature monoplontic female gametophyte.Compared with the sexual female gametophyte,bradygenesis and abortion can be frequently observed during the development of diplosporous female gametophyte.Only 25% of them are normal.The characteristic of diplosporous reproduction is discussed. |
