氮离子束辐照对烟草种子发芽率的影响

Effects on Germination Percent of Tobacco Seeds Irradiared by Nitrogen Ion Beam

用不同剂量的氮离子束辐照不同烟草品种的干种子，对种子发芽率进行了测定。结果表明，不同品种间、不同处理剂量间差异均达显著水平；品种与剂量互作效应间差异也达显著水平。

Tobacco dry seeds of diferent cultivars were irradiated with different doses of N ion beams. The resultsshowed that garmination percents were significantly different among cultivars,dreatments and the interaction ofthem.
