菠萝开花诱导及其生理与分子基础

摘要

Pineapple flowering includes "natural flowering" and "induction flowering". In nature, the flowering rate is much influenced by environmental factors with great uncertainty. In practice, the induction of flowering by application of ethylene or CaC2 is widely used in commercial production of pineapple to regulate the time of pineapple to market. And now, annual commercial production of pineapple has been achieved by combining with reasonable arrangement of planting time and use of flowering induction technology. The research progress of pineapple blossom was reviewed in this paper, including natural flowering, induction flowering and their physiological and molecular bases, and the prospects for future research.%菠萝开花分为自然开花和诱导开花两大类.由于菠萝自然开花的时间和开花率受环境因素影响较大,具有较大的不确定性,在实践中常常通过施用乙烯利或CaC2诱导菠萝开花达到调节菠萝上市时间的目的.通过合理安排种植时间与使用开花诱导技术,目前已经实现反季节生产和周年生产菠萝的目标.笔者对近年来菠萝自然开花、诱导开花及其生理、分子基础方面的研究进展进行了综述,并展望了该领域今后的研究方向.
