Abstract
This experiment was conducted with two soybean species of BX10 and BL2,to estimate phosphoenolpyruvate phosphatase(PEPP) activities of soybean leaves and roots under abiotic stresses of P deficiency,Al toxicity,salt excess,drought,microelements(Fe,Mn,Cu,Zn) excess as well as deficiency.The results showed that:(1) 14 d period stresses of both P deficiency and Al toxicity resulted in significant and additive increasing in root PEPP activities;(2) both Al toxicity and its combination with P deficiency stresses significantly increased leaves PEPP activities of BL2,the sensitive variety to P deficiency and Al toxicity;(3)salt excess,drought and 14d period stresses of microelement (Fe,Cu,Mn,Zn) excess other than deficiency significantly increased both roots and leaves PEPP activities,however,14d period stress of Mn deficiency significantly decreased roots and leaves PEPP activities.
