doi:10.11924/j.issn.1000-6850.2012-3139

Abstract

Abstract: The maize seed（Zhengdan 958）were selected to study the relationship between germination and starch conversion in salty stress by germinating experiment under different concentrations of NaCl and Na2SO4. Germination rate, bud dry weight, root dry weight, starch, soluble sugar and sucrose content was determined. The results showed that, with increasing Na+ concentration, corn seed germination rate, radicle growth and plumule growth decreased, which is consistent with the trend of starch conversion, sucrose and soluble sugar content in seed, and maize seed germination rate was a significant positive related to starch conversion (p<0.05). There was higher sucrose content of seed in NaCl treatment than in Na2SO4 treatment. Soluble sugar content of seed in NaCl treatment was higher in in Na2SO4 treatment in low Na + concentration; however, it is controversial in higher Na+ concentration. Thus, increased salty concentration and species decreased the starch conversion rate, changed the distribution of sugar, it can be seen to change supply and demand of energy during germinating period, and result in reduced germination rate.
