【摘要】 本文以唐菖蒲品种Rose Supreme的籽球为外植体,研究了酯氧合酶(LOX)抑制剂水杨苷异羟肟酸(SHAM)和LOX代谢产物茉莉酸甲酯(MJ)对唐菖蒲试管结球的影响。结果表明:与对照相比,经SHAM处理的组培苗结球时间明显推迟,且随着SHAM浓度的增加,不仅结球时间明显推迟,而且结球率逐渐降低;经MJ处理的组培苗的结球率增加,并且显著高于对照,但是随着MJ浓度的升高,结球率有所降低,0.5mmol/L的MJ为唐菖蒲试管结球的最佳浓度。以上结果说明,SHAM对唐菖蒲试管结球起抑制作用,而MJ有明显的促进作用。更多还原

【Abstract】 The cormels of Gladiolus cultivar‘Rose Supreme’were used as explants to study the effects of SHAM and MJ on corm formation in vitro,which SHAM is the inhibitor of LOX,and MJ is the product of LOX metabolism.The results indicated that compared with CK,the time of corm forma tion was obviously delayed by SHAM,and the percentage of corm formation was also reduced with the increasing of SHAM concentration.The percentage of corm formation was raised by MJ,and the best concentration of MJ to induce the corm formation was 0.5mmol/L.But,the percentage of the corm for- mation was reduced as the increasing of MJ concentration.These results demonstrated that SHAM re- strained the corm formation and MJ accelerated the corm formation obviously.更多还原
