A Study on Endogenous Inhibitors of Nitraria roborowskii Kom. Seeds
Nitraria roborowskii Kom. seeds have deep dormancy characteristics. Under natural conditions, the germination rate of the seeds is low, and the germination time is long. Therefore, exploring the reasons for seed dormancy is highly important. The results showed that the extracts of the methanol phase, ethyl acetate phase, petroleum ether phase and water phase of N. roborowskii seeds all had a significant inhibitory effect on the germination rate and germination index of Brassica rapa seeds, among which the extract of the methanol phase had the strongest inhibitory effect, and the inhibitory effect decreased in the following order from the strongest to the weakest: methanol phase > ethyl acetate phase > petroleum ether phase > water phase. The components of the methanol phase, ethyl acetate phase and petroleum ether phase ether extracts of N. roborowskii seeds were identified by gas chromatography–mass spectrometry (GC–MS). The experimental results showed that the organic phase extracts of N. roborowskii seeds contained a variety of inhibitory compounds, which included 4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl-dibutyl phthalate; 4-((1E)-3-hydroxy-1-propenyl)-2-methoxyphenol; 13-docosenamide, (Z)-; 3-hydroxy-4-methoxybenzoic acid; vanillin; 2,4-di-tert-butylphenol; and cyclohexane, ethyl-. The seeds of N. roborowskii contain a variety of endogenous inhibitors, which are the main reason for its seed dormancy.
