水涝胁迫对豫楸1号嫁接苗MDA和质膜透性的影响

MDA and Membrane Permeability Response to Submergence Stress of Four Kinds of Stocksgrafted Seedlings of Catalpa bungei cl. ‘Yu-1’

通过对水涝胁迫条件下豫楸1号4种砧木嫁接苗MDA和质膜透性的测定,结果表明:在整个涝渍胁迫期间,豫楸1号4种砧木嫁接苗的质膜透性和MDA含量均呈上升趋势。I号与II号间的MDA差异达到显著水平(p<0.05)

MDA and Membrane permeability of four stocks grafted seedlings of Catalpa bungei cl.‘Yu-1’ were studied on waterlogging.The result showed：in the condition of waterlogging,MDA and Membrane permeability of four kinds of grafted seedlings of Catalpa bungei cl.‘Yu-1’ showed the trend of rising-declining.MDA of which had obvious difference（p0.05） with grafted seedlings between I and II.
