【 摘 要 】

Problem statement: To determine the effect of MgCl₂ on radish (Raphanus sativus), plants weregrown in controlled environmental growth chambers and given one of three watering treatments; 0.01, 0.1and 0 M (control) MgCl₂. Approach: At high concentrations (0.1 M), MgCl₂ was toxic resulting in verylow (44%) germination rates and the subsequent death of all but three undersized plants over the 28 daygrowth period. Results: At lower concentrations (0.01 M), MgCl₂ resulted in enhanced germination rates(5.55%) and a mass increase (39.54%) over the control. Conclusion/Recommendations: While lowconcentrations of MgCl₂ resulted in an increase in total biomass, biomass allocation was shifted largely fromroots to shoots (55.88% higher root/shoot ratio in the control).
