摘要:

为了筛选出耐涝能力良好的番茄(Solanum)种质,以50份番茄种质作为研究对象,比较其在半淹及全淹处理后的成活率和各项生理指标,筛选出12个在7 d全淹处理后存活率为100%的耐涝型番茄种质,发现耐涝型番茄种质在普通番茄(S. lycopersicum)、樱桃番茄(S. lycopersicum var. cerasiforme)和醋栗番茄(S. pimpinellifolium)中均有分布;进一步对耐涝型番茄TK017和淹水敏感型番茄TK039的分析表明耐涝型番茄TK017在全淹胁迫下能够更有效地控制体内活性氧含量,从而提高番茄的耐涝能力。

Abstract:

To screen out the tomato(Solanum) germplasm with waterlogging tolerance, 50 tomato germplasm were selected as the research object, and the survival rate and physiological indexes were compared after semi-submerged and submerged treatments respectively. The results showed that 12 waterlogging tolerant tomato germplasm with 100% survival rate after seven days submergence treatment were selected, and 12 waterlogging-tolerant germplasm were observed and distributed in S. lycopersicumS. lycopersicum var. cerasiforme and S. pimpinellifolium respectively. Further analysis on waterlogging-tolerant tomato TK017 and waterlogging-sensitive tomato TK039 revealed that tomato TK017 could control the content of reactive oxygen species more effectively under submergence condition, and improved the waterlogging tolerance of tomato.

Key words: tomato, waterlogging tolerance, abiotic stress
