| 摘 要： | 比较研究了大穗型和多穗型小麦品种的分薛发育特征及其代谢基础。结果表明，与多穗型品种相比，单株分蘖较少的大穗型品种分蘖期具有较低的IAA氧化酶（IAAO）活性、较高的IAA含量和较强的碳代谢活性。在分蘖的两极分化期，大穗型品种在碳、氮代谢和同化物分配方面存在较强的主茎优势，因此，其分蘖较难继续发育成穗。

| Abstract: | The metabolic bases of tiller growth of large-spike and multi-spike wheat cultivar were comparatively studied.The results indicated that,compared with multiple-spike cultivar,large-spike cultivar with fewer tillers per plant had lower activity of indole acetic acid oxidase (IAAO),higher IAA content and stronger carbon metabolism during tillering stage.At tiller polarizing stage,the main shoot of large-spike cultivar had obvious dominance in carbon and nitrogen metabolism and distribution percentage of 14C-assimilate.Therefore,it was more difficult for tillers of large-spike cultivar to develop to bear an ear. |
