摘要:
本试验探究稀土微肥对盐(Na2CO3)胁迫下番茄种子发芽率、发芽势、子叶展开率和体内丙二醛(MDA)含量、过氧化物酶(POD)活性及相对电导率的影响.结果表明:经稀土微肥处理后,受盐胁迫番茄种子的发芽率、发芽势和子叶展开率均有所升高,而MDA含量、POD活性和相对电导率则呈现相对降低趋势.这个规律说明了外源稀土微肥可以缓解碱性盐对番茄种子的胁迫,降低盐胁迫下番茄幼苗体内抗氧化酶活性的活性,降低膜脂过氧化水平,减缓碱性盐胁迫对植株的伤害.且在不同Na2<
Abstract:
The experiment explored on the condition that rare-earth elements treated salt(Na2CO3)the germination rate, germination potential, cotyledon expansion rate of tomato seeds, and the effects of MDA content and POD activity to relative conductivity. The results showed that the rare-earth element treatments resulted in increased seed germination rate, germination potential, cotyledon expansion rate, while the content of MDA, POD activity, relative conductivity emerged equivalent lower trend. It also showed that applying rare-earth elements can relieve the stress effect of alkaline salt on tomato seeds, decrease the activity of antioxidase in tomato seedlings under salt stress, reduce the level of membrane lipid peroxidation, and alleviate the damage of salt stress to plants. At different concentration of Na2CO3 in the current experiment,application of 150 mg/L rare earth elements achieved a better alleviation of adverse effects of salt stressed tomato seeds and seedlings.
