In this research, a cross-interactions of environmental stress such a salinity and the primary metabolism was investigated in a developing fruit of tomato. It was revealed that i) salinity stress enhanced sugar accumulation by promoting carbon influx and starch accumulation in an immature fruit, ii) salinity stress enhanced amino-acid biosynthesis but it was not so effective on metabolism of organic acids. Additionally, the effect of salinity treatment on seed germination was also studied. The salinity stress significantly enhanced seed germination through activation of gibberellin biosynthesis.

本研究以番茄果实为材料，研究了环境胁迫（如盐胁迫）与果实初生代谢的交互作用。结果表明：（1）盐胁迫通过促进未成熟果实的碳流入和淀粉积累来促进糖的积累;（2）盐胁迫促进了氨基酸的合成，但对有机酸的代谢影响不大。此外，还研究了盐处理对种子萌发的影响。盐胁迫通过激活赤霉素的生物合成显著促进种子萌发。
