Abstract
To understand the effects of low oxygen stress on rapeseed seedlings,Brassica napus L.inbred line GAC and cultivar Zhongshuang 10 were used to investigate adventitious rooting in liquid medium with 1mg/L oxygen.Results indicated that 6d of low oxygen stress significantly decreased seedling dry weight by 45.3% in GAC and 22.3% in Zhongshuang 10 respectively.Adventitious root growth was significantly induced.The 6d low oxygen treatment increased the adventitious roots by 88.6% in GAC and 137.3% in Zhongshuang 10.Excision of adventitious roots led to decrease of seedling dry weight by 24.9% of GAC and 35% of Zhongshuang 10 respectively.Pretreatment of low oxygen(6d-low oxygen treatment in liquid medium with 0.5% agar) and aeration exercise increased the dry weight and the number of adventitious roots of Zhongshuang 10,but had no obvious effect on GAC.Results indicated that correlation between adventitious roots and dry weight was larger under low oxygen stress than normal condition.It indicated that adventitious root formation is one of the important physiological mechanisms for rape seedlings to adapt to low oxygen stress.
