摘要: 用SPAC理论分析大豆、花生、玉米、甘薯4种作物水势分布特点及耐旱性结果表明，植物叶片水势是植物水分状况的较好生理指标，玉米根、叶间水势差为0.293MPa，叶位间水势差为0.067MPa。不同作物叶片水势差异显著，作物叶片水势越高，其耐旱性越强。

Abstract: The distribution characteristics of water potential and drought tolerance of soybean,poanut,corn and sweet potato are analyzed with SPAC theory.The results show that the leaves water potential of crops is a physiological index reflecting the water content of crops,the difference of water potential between roots and leaves of corn is 0.293MPa and that among leaves is 0.067MPa.The leaves water potential is outstanding among different crops,that is more high and crops drought tolerance is more strengthened.
