摘　　要：本研究结果表明，采用２，４－Ｄ浸穗法结合低浓度激素培养基进行小穗培养，可以明显改善小麦和玉米杂交种颖果、幼胚及胚乳的发育状况，得胚率由２．１％提高到１２．０％；同时表明低浓度激素对杂种发育有着明显的调节作用，但２，４－Ｄ和ＧＡ优于ＫＴ。The developthent of wheat×maize hybrid caryopsis,young embryo and endosperm is improved significantly through spikelet culture in the medium containing low-concentrated promoting substances and dipping spikes in 2,4-D solution.The percentage of embryo obtained is increased from 2.1% to 12.0%;low-concentrated promoting substances have significant regulation effect to the development of young embryo, and the effect of 2,4-D and GA are better than that of KT.
