Abstract:

次生休眠是指原来无休眠的种子由于不适宜环境条件的影响而诱发的休眠,是导致油菜产区地下种子库长期存在和油菜自生苗繁衍并造成危害的根本原因.本研究用4种埋藏法和PEG处理评价油菜49个品种种子次生休眠特性的遗传多样性.结果表明,不同品种甘蓝型油菜种子的休眠存在显著性差异,4种埋藏检测方法检测油菜次生休眠特性的变异范围为0~44%,广义遗传率为40%~53%.49个品种中次生休眠率低于2%的品种占45%,次生休眠率2%~20%的品种占38.8%,次生休眠率20%~40%的品种占16.3%(如早丰4号、中双9号、红油2号、中双5号和Tower等).PEG法检测的次生休眠性广义遗传率达到82.1%.相关性分析表明,甘蓝型油菜种子在不同埋藏时间和深度得到的休眠性呈极显著相关,而PEG诱导甘蓝型油菜种子数据只与部分条件下的埋藏处理之间存在相关性.埋藏实验显示,部分品种的种子可进入深层次的休眠,需要破眠处理才能发芽,这些品种的种子可能会在土壤中存活更长时间.
