本文以半夏试管苗为材料,探讨了不同浓度的甘露醇、PP333和ABA对半夏延缓生长的保存效应,并采用ISSR标记对保存材料再生植株的体细胞遗传变异进行了检测。结果表明,三种物质均能有效抑制半夏试管苗的生长,保存10M而不继代,存活率高;与正常继代试管苗相比,再生植株的形态、增殖倍数和生根能力没有显著差异,最佳浓度分别为甘露醇2%-4%,PP3332.0mg·L-1,ABA2.0-4.0mg·L-1。在添加了2%-4%甘露醇或2.0mg•L-1PP333的培养基上,保存植株经ISSR分子检测,未检测到变异;而保存在添加了2.0-4.0mg•L-1ABA培养基上的植株,出现了1条新增标记,1条缺失标记,位点变异率为1.6%,个体变异率为30%。因此,ABA不宜用于半夏试管苗的缓慢生长法保存,但有助于新突变体的产生,在半夏种质创新上具有特殊意义。2.半夏的缓慢生长法保存及体细胞遗传变异的ISSR检测

,2.0-4.0mg·L-1ABA。AsdetectedbyISSRmolecular,nopolymorphic/aberrantmarkerwasscored/observed/investigated/obtainedfromtheregeneratedplantletsconservedonmediumwiththeadditionof2%mannitoland2.0mg.L-1PP333.在添加了2%-4%甘露醇或2.0mg•L-1PP333的培养基上,保存植株经ISSR分子检测,未检测到变异;However/Conversely,anewmarkerandaabsentmarkwereobservedfromthatconservedonmediumsupplementedwith2.0mg.L-1ABA,andthelocusorindividualvariationratewas1.6%or30%,respectively.而保存在添加了2.0-4.0mg•L-1ABA培养基上的植株,共出现了1条新增标记,1条缺失标记,位点变异率为1.6%,个体变异率为30%。

Therefore,ABAwasnotsuitableforinvitroconservationofPinelliagermplasm.Rather,itmightbeusedtogeneratenewmutant,whichdemonstratedhighlyapromisingroleinthecreationofnewPinelliaternategermplasm.因此,ABA不宜用于半夏试管苗的缓慢生长法保存,但有助于新突变体的产生,在半夏种质创新上具有特殊意义。Theenhancementofdroughttoleranceforpigeonpeainoculatedbyarbuscularmycorrhizaefungi
