Effects of seed priming on Lycium barbarum seed germination under salt stress
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 6
Abstract
"Lycium barbarum is a kind of representative perennial shrub with drought and salinity tolerance， and it often grows in desert of China's northwest. Seeds of Ningqi No.1 were primed with 100 mmol/L NaCl. Using petri dish techniques，the primed seeds under H2O（control） were subjected to salt stresse of 6 NaCl concentrations （20，40，60，80，100，120 mmol/L）. The effects of the seed priming and salt stress on seed germination were then investigated. The results showed that with priming or without priming，germination speed of Ningqi No.1seeds slowed down significantly. The germination percentage，germination energy and germination index all declined obviously with increased NaCl concentration，and the germination process showed a significant delay. Under the stress of 120 mmol/L NaCl solution，the germination rate of the unprimed group decreased by 71.3% than the control group， and the germination rate of the primed group decreased by 71.3% compared with the control group. Compared with unprimed seeds under the same NaCl concentration，primed seeds had increased germination speed and shortened the germination process in different extent. The germination energy and germination index of the primed seed were significantly higher than those of unprimed seeds. The germination energy of the primed control group was 15.4% higher than the unprimed group. The results suggested that Lycium barbarum seed priming shortened the germination process under salt stress，improved the uniformity of seed germination，but the impacted on the final germination rate was not significant."
