本文以半夏試管苗為材料，探討了不同濃度的甘露醇、PP333和ABA對半夏延緩生長的保存效應(yīng)，并采用ISSR標(biāo)記對保存材料再生植株的體細胞遺傳變異進行了檢測。結(jié)果表明，三種物質(zhì)均能有效抑制半夏試管苗的生長，保存10M而不繼代，存活率高；與正常繼代試管苗相比，再生植株的形態(tài)、增殖倍數(shù)和生根能力沒有顯著差異，最佳濃度分別為甘露醇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的培養(yǎng)基上，保存植株經(jīng)ISSR分子檢測，未檢測到變異；而保存在添加了2.0-4.0mg?L-1ABA培養(yǎng)基上的植株，出現(xiàn)了1條新增標(biāo)記，1條缺失標(biāo)記，位點變異率為1.6%，個體變異率為30%。因此，ABA不宜用于半夏試管苗的緩慢生長法保存，但有助于新突變體的產(chǎn)生，在半夏種質(zhì)創(chuàng)新上具有特殊意義。2.半夏的緩慢生長法保存及體細胞遺傳變異的ISSR檢測

，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的培養(yǎng)基上，保存植株經(jīng)ISSR分子檢測，未檢測到變異；However/Conversely,anewmarkerandaabsentmarkwereobservedfromthatconservedonmediumsupplementedwith2.0mg.L-1ABA,andthelocusorindividualvariationratewas1.6%or30%,respectively.而保存在添加了2.0-4.0mg?L-1ABA培養(yǎng)基上的植株，共出現(xiàn)了1條新增標(biāo)記，1條缺失標(biāo)記，位點變異率為1.6%，個體變異率為30%。

Therefore,ABAwasnotsuitableforinvitroconservationofPinelliagermplasm.Rather,itmightbeusedtogeneratenewmutant,whichdemonstratedhighlyapromisingroleinthecreationofnewPinelliaternategermplasm.因此，ABA不宜用于半夏試管苗的緩慢生長法保存，但有助于新突變體的產(chǎn)生，在半夏種質(zhì)創(chuàng)新上具有特殊意義。Theenhancementofdroughttoleranceforpigeonpeainoculatedbyarbuscularmycorrhizaefungi
