摘要
为了筛选蓝靛果忍冬抗寒品种,以9个蓝靛果忍冬品种(蓝鸟、伊利亚特、炭火、谢丽娜、加洛奇卡、落火炭、别列里、蓝纺锤及阿索里)1年生枝条为材料,研究低温胁迫(-15、-20、-25、-30、-35、-40℃)对蓝靛果忍冬电导率及忍冬抗氧化酶活性的影响。结果表明:各试验品种的抗寒性随着温度的变化而变化,在-15^-25℃之间的电导率较小,SOD活性较高,POD活性在-25^-40℃时较高,所有品种的SOD、POD、CAT活性的变化趋势基本一致。在-15^-20℃期间,蓝纺锤抗寒性表现最好;在-30^-40℃期间,加洛奇卡,别列里以及落火炭的抗寒性优于其它品种。
In order to screen out some cold-resistant cultivars in Lonicera caeruleae, using one-year-old branches from nine eultivars in L. caeruleae （Blue jays, Iliad, Coals, Li-na xie, Faoqxa, Charcoal, Bepezb, Blue spindle and Azauri） as materials, influences of low temperature stress （ -- 15, -- 20, -- 25, -- 30, -- 35 and -- 40℃ ） on conductivity and antioxidant enzyme activity in L. caeruleae were studied. The results showed that： cold resistance of the tested varieties changed with temperature changing, electrical conductivity was less and SOD activity was higher from -- 15 ℃ to -- 25 ℃ , POD activity was higher from -- 25℃ to -- 40 ℃, and change tendencies of SOD, POD and CAT activities in all the cultivars were basically the same. During the period of -- 15℃ to -- 20 ℃, Blue spindle had the best cold-resistant expresssion. During the period of -- 30℃ to -- 40 ℃, cold resistances of Fa.~oqKa, Bepenl, and Charcoal were superior to the other cultivars.
