摘 要 ：对10属种十字花科植物与油菜萝卜胞质不育系杂交时花粉在柱头上粘合、萌发、花粉管伸长等情况进行观察。结果表明：（1）海甘蓝花粉粒粘合较难；（2）48 h内无瓣焊菜〖WTBX〗(Rorippa dubia)〖WTBX〗、毛果诸葛菜(Orychophragmus violaceus)、桂竹香(Cheiranthus cheiri)、海甘蓝(Crambe abyssinica)花粉管的伸长受阻于花粉萌发启动之时，花粉壁内形成胼胝质塞；播娘蒿、紫罗兰、荠菜花粉管伸长但未进入乳突细胞；芝麻菜花粉管进入乳突细胞而未进入柱头，‘浠水白’(Brassica campestris)、蓝花子有花粉管进入柱头及花柱而未进入胚囊。

Abstract:Pollen grain adhesion, germination and pollen tube growth were observed in intergeneric crosses between ten taxa and Ogu CMS.The pol len grains of Crambe abyssinica hardly adhered to the stigma of Og u CMS. Observations made within 48 h showed that the pollen tubes of Rorippa dubia(Pers.) Hara, Orychophragmus violaceus var. lasiocarpus Migo, Cheriranthus cheiri L.and Crambe abyssisca were obstructed and callose plugs formed in sporoderm at the start of pollen germination. The pollen tubes of Descurainia sophia(L.) Webb. ex Prantl, Matthiola incana(L.) R. Br.and Capsella bursa_pastoris(L.) Medic grew but failed to penetrate the papilla cells. The pollen tubes of Eruca sativa Mill. var. sativa penetrated the papilla cells, but did not penetrate the stigma. The pollen tubes of Brassica campestris huibai’ and Raphanus sativus L.var raphanistroides(Makino) Makino entered the stigmata and styles but did not penetrate the embryo sacs.
