Abstract:

This experiment chooses seeds of wheat and corn as material, which were treated by 200 g· 24 h,200 g · 36 h,700 g · 12 h,700 g ·24 h,1 500 g · 4 h and 1 500 g ·12 h. Their seed＇s viability and morphological ind/ces （ plant height,root length） ,contents of chlorophyll and root＇s viability werre observed. Through comparing with CK, affect of gravity to plant was analyzed. The result showed that hypergravity treatment might influence the growth of young plant. Time and speed of hypergravity treatment are important factors. The best treatment in this trial is 1 500 g · 4 h,which was favorable to young plants, while the treatments of 700 g · 24 h could even lead the young plants to death. Comparison between wheat and corn has proofed that same treatment of hypergravity would have different effects on different plants.
