摘 要：
采用盆栽试验,在正常水分管理和干旱胁迫条件下研究了转DREB基因抗旱大豆对土壤脲酶、纤维素酶、磷酸酶和过氧化氢酶活性的影响。结果表明,转基因抗旱大豆和非转基因大豆在正常土壤水分管理下,根际土壤中脲酶、纤维素酶、磷酸酶和过氧化氢酶活性在大豆VE、R1、R4期无显著差异。在干旱胁迫下,转基因抗旱大豆和非转基因大豆在VE和R1期土壤脲酶活性显著降低,R1和R4期土壤纤维素酶活性显著降低,R1期土壤磷酸酶活性分别呈显著增高和显著降低趋势,VE和R4期磷酸酶活性分别表现显著降低和无影响的作用,对土壤过氧化氢酶活性无显著影响。

摘 要：
Pot culture method was used to study the effect of the transgenic drought resistant soybean(TDRS) and none transgenic soybean(NTS) on soil urease,cellulose,phosphatase and hydrogen peroxidase activity.The results showed that TDRS and NTS had no effects on soil urease,cellulose,phosphatase and hydrogen peroxidase activity in rhizosphere at VE,R1 and R4 growth stage under the normal soil water condition.Under water stress condition urease activity was significantly decreased at VE and R1 growth stage,and cellulose activity was also significantly decreased at R1 and R4 growth stages in both TDRS and NTS rhizosphere soil.At R1 growth stage phosphatase activity was significantly increased in TDRS rhizosphere and decreased in NTS rhizosphere.Phosphatase activity was significantly decreased in TDRS rhizosphere and no effects in NTS rhizosphere at VE and R4 growth stage.TDRS and NTS have no effects on soil hydrogen peroxidase activity.
