Changes of Lycopene, Beta-carotene, Glucose, GA3 and ABA Contents in Different Parts of Tomato
Journal Title: Biotechnology Journal International - Year 2016, Vol 12, Issue 3
Abstract
Aims: This research studied the dynamic changes of main pigments, glucose, GA3 (Gibberellic acid) and ABA (Abscisic acid) contents in different parts of tomato fruit during the ripening stage, and provided references for the further research for the coloring mechanism of tomato fruits. Study Design: When the second cluster of tomato fruits reached green mature stage, fruits were labeled and sampled. The fruits from each ripening stage were sampled and dissected to individual parts for measuring the contents of lycopene, beta-carotene, glucose, GA3 and ABA. Place and Duration of Study: Horticultural College, between February 2014 and March 2015. Methodology: The contents of lycopene, beta-carotene, glucose, GA3 and ABA were determined by HPLC (High Performance Liquid Chromatography). Results: The contents of lycopene and glucose increased during the ripening of tomato fruits, and the contents of β-carotene increased after slightly decreased. At the redⅡstage, the maximum contents of lycopene and glucose were in the peripheral pericarp, and the maximum content of β-carotene was in pectin. The contents GA3 decreased during ripening stage, and the minimum content of GA3 was in peripheral pericarp at the redⅡstage. The change of ABA contents which stayed in a low level in all parts was like a bimodal curve during the whole ripening stage. Conclusion: Accumulation of lycopene and β-carotene was accompanied by the increasing of glucose and ABA contents, and by the decreasing of GA3 content.
