【摘要】 在环境释放条件下,比较了转基因青蒿及其野生型受体的基本农艺性状、抗逆性及耐常用除草剂等特性。在旱、盐胁迫下,通过测定3种转基因品系和其野生型受体的叶片相对含水量、过氧化物酶及脯氨酸等生理指标,比较了转基因青蒿和野生型的耐受性。结果显示,转基因青蒿品系ANF176、GFH13的株高、茎粗显著低于其野生型受体,转基因青蒿品系SQS159的冠幅和千粒重显著高于其野生型受体。其他指标的比较试验研究显示转基因青蒿品系与其野生型受体没有显著差异性。在本试验条件下,这3种转基因青蒿品系具有与野生型类似的抗逆能力(耐盐性、耐旱性),转基因青蒿与野生型对2种除草剂克无踪和金都尔不具有耐受性。更多还原

【Abstract】 The basic agronomic characteristics of transgenic A.annua lines and the wild-type were evaluated,and the physiological responses to the drought and salt stress of three transgenic A.annua varieties and wild-type were compared by determining the relative water content of leaves,POD,proline and so on.The results indicated that there were significant differences in plant height and stem diameter between transgenic A.annua varieties ANF176,GFH13 and wild-type,in crown width and 1000-seeds weight between transgenic A.annua variety SQS159 and wild-type.The difference between three transgenic A.annua varieties and wild-type in other agronomic characteristics was not significant.Moreover,under the experiment condition transgenic A.annua varieties and the wild-type had similar stress tolerances to salt and drought.Three transgenic A.annua lines and the wild-type were not tolerant to the two herbicides,paraquat and s-metolachlor.更多还原
