用高粱水提取物（SWE）进行种子引发可增强作物对盐胁迫的耐受性；然而，到目前为止，SWE 在盐度下对亚麻荠作物的应用尚未有记录。本研究评估了 SWE 种子引发在提高亚麻荠盐胁迫耐受性方面的潜在作用。底漆（用 5% SWE 和蒸馏水水底漆）和未底漆种子在对照（无盐）和盐胁迫（10 dS m−1）条件下播种。盐度降低了亚麻荠的出苗和生长，而用 SWE 进行种子引发则改善了对照和胁迫条件下的生长。在盐胁迫下，与未处理的植物相比，用SWE引发的种子提高了出苗率（96.98%）、根长（82%）、芽长（32%）、根干重（75%）、芽干重（33%）、α-淀粉酶活性（66.43%）、叶绿素含量（60-92%）、抗氧化酶活性（38-171%）和芽K+离子（60%）。类似地，在胁迫条件下，通过用 SWE 进行种子引发，与未引发的种子相比，过氧化氢、丙二醛 (MDA) 含量和芽 Na+ 离子分别减少了 60%、31 和 40%。因此，SWE种子引发可用于增强亚麻荠对盐胁迫的耐受性。
Seed priming with sorghum water extract (SWE) enhances crop tolerance to salinity stress; however, the application of SWE under salinity for camelina crop has not been documented so far. This study evaluated the potential role of seed priming with SWE in improving salt stress tolerance in camelina. Primed (with 5% SWE and distilled water-hydropriming) and nonprimed seeds were sown under control (no salt) and salt stress (10 dS m−1) conditions. Salinity reduced camelina’s emergence and growth, while seed priming with SWE improved growth under control and stress conditions. Under salt stress, seed priming with SWE enhanced emergence percentage (96.98%), increased root length (82%), shoot length (32%), root dry weight (75%), shoot dry weight (33%), α-amylase activity (66.43%), chlorophyll content (60–92%), antioxidant enzymes activity (38–171%) and shoot K+ ion (60%) compared with nontreated plants. Similarly, under stress conditions, hydrogen peroxide, malondialdehyde (MDA) content, and shoot Na+ ion were reduced by 60, 31, and 40% by seed priming with SWE, respectively, over the nonprimed seeds. Therefore, seed priming with SWE may be used to enhance the tolerance against salt stress in camelina.
