摘要
以甘蓝型油菜籽为材料,研究了含水量(6.8%、8.3%、9.8%)、储藏温度(20℃、25℃、30℃、35℃)、储藏方式(充氮气调、常规密闭)等不同条件下油菜籽电导率、发芽率、发芽势等生理指标的变化,结果表明:在120 d期间,油菜籽电导率呈升高趋势,发芽率、发芽势呈降低趋势,其升高或降低幅度与储藏条件有关.在20℃、充氮条件下,含水量6.8%的油菜籽电导率数值低、升幅小,其发芽率高、降幅小.低水分、准低温(20℃)加充氮气调更能保持油菜籽的生理活性.
In this paper, we studied the effects of different moisture contents （6.8% , 8.3% , 9.8% ）, storage temperatures （20℃ ,25℃ ,30℃,35℃ ） and storage manners （controlled atmosphere storage with N2. conventional airtight storage） on the physiological indexes of Brassica napus seeds,such as conductivity, germination rate and germination potential. The results showed that the conductivity increased,and the germination rate and the germination potential decreased after storage for 120 days,and the increasing or decreasing amplitude was related to the storage condition. Under the condition of controlled atmosphere storage with 98% N2 at 20℃ ,Brassica napus seeds with 6.8% moisture content had low conductivity and small increasing ampli-tude, and high germination rate and low decreasing amplitude. Therefore, the physio-logical indexes of Brassica napus seeds could be well kept under the conditions of low moisture content, quasi-low temperature （20℃） and controlled atmosphere stor-age with 98% N2.
