摘要
为了明晰几种主要的植物激素在马铃薯块茎形成中的作用,本研究采用LC-MS/MS法测定了马铃品种‘PB06’及品种‘会-2’块茎发育不同时期叶片、匍匐茎/块茎组织中植物激素ABA、GA3、JA和IAA含量的动态变化。结果显示,随着块茎的发育,匍匐茎/块茎中ABA及JA含量增加;叶片中ABA含量逐渐增加,JA含量先上升后下降,两个品种变化趋势相同。GA3的积累随着匍匐茎的膨大而下降;IAA含量峰值出现在匍匐茎膨大时,并且在之后匍匐茎的膨大中仍然维持高含量水平。表明,IAA及GA3对匍匐茎的伸长是必要的,ABA、JA是诱导块茎形成的正调控因子,GA3为负调控因子。该研究结果对开展植物激素调控块茎形成机理的研究具有重要的支撑作用。
To clarify the roles of key plant hormones in the formation of potato tubers, we followed the dynamic changes of ABA, GA3, JA and IAA content during the tuber four consecutive developmental stages of Solanum tuberosum L. 'Hui 2' and 'PB06' by LC-MS/MS. The results showed that the contents of ABA and JA in leaves and stolon/tuber and accumulation of JA in stolon/tuber increased throughout the whole tuber development, while JA amounts increased from tuberization induction to tuber initiation and decreased from tuber grow to ripe stage. The accumulation of GA3 decreased with the swelling of stolons. IAA amounts showed an increase-decrease tendency with a peak at tuber initiation stage. The results showed IAA and GA3 are essential for elongation of stolon. In addition, ABA and JA are positive regulatory factors for tuberization, while GA is a dominant negative regulator that inhibits tuber formation. The results play a supporting role in the research on mechanism of phytohormones involved tuberization.
