Abstract A laboratory experiment was carried out to evaluate the impact of the nanoparticles of water treatment residuals (nWTRs) and salt stress on germination and growth parameters of cucumber seedling. The interaction between three nWTRs treatments (0, 500, and 1000 mgL−1) nWTRs and five saline solution (fresh water: sea water) treatments had 0.70, 2, 3, 6, and 11 dSm−1 were studied. The results revealed that increasing salinity levels significantly reduced the percentage of germination (GP) for the primed seeds treated in fresh water and nWTRs. The GP reduction was higher in seeds primed in fresh water compared to which primed in nWTRs. Salt stress negatively affected radicle length of cucumber seedling for both priming treatments. However, this impact was more pronounced for the primed seeds treated in fresh water than which treated in nWTRs at high salinity stress. Priming in nWTRs significantly decreased the root radius of cucumber seedlings, and the1000 mgL−1 priming treatment obtained a lowest value of radicle radius. Increasing salt concentration in culture medium reduced total biomass of cucumber seedling, however for the primed seeds treated in nWTRs, the total biomass was increased in comparison with which treated in fresh water. Salt tolerance and vigor indices were significantly (p < 0.01) affected by salinity levels, nWTRs treatments and their interaction. It can be concluded that nWTRs are ameliorating materials for plant growth under salt stress conditions.

水处理残留物纳米颗粒中的种子引发可促进盐胁迫下黄瓜幼苗的发芽和生长

摘要 通过室内实验，研究了纳米颗粒水处理残留物（nWTRs）和盐胁迫对黄瓜幼苗萌发和生长参数的影响。研究了三种 nWTRs 处理（0、500 和 1000 mgL-1）nWTRs 和五种盐水溶液（淡水：海水）处理之间的相互作用，分别为 0.70、2、3、6 和 11 dSm-1。结果表明，增加盐度水平显着降低了在淡水和 nWTR 中处理过的种子的发芽率 (GP)。与在 nWTR 中引发的种子相比，在淡水中引发的种子的 GP 减少更高。盐胁迫对两种引发处理的黄瓜幼苗胚根长度都有负面影响。然而，这种影响对于在淡水中处理过的种子比在高盐度胁迫下在 nWTR 中处理的种子更为明显。nWTRs的引发显着降低了黄瓜幼苗的根半径，1000 mgL-1引发处理获得了最低的根半径值。培养基中盐浓度的增加降低了黄瓜幼苗的总生物量，但是对于在 nWTR 中处理的种子，与在淡水中处理的相比，总生物量增加了。耐盐性和活力指数受盐度水平、nWTRs 处理及其相互作用的显着影响（p < 0.01）。可以得出结论，nWTRs 是盐胁迫条件下植物生长的改善材料。1000 mgL-1引发处理获得了胚根半径的最低值。培养基中盐浓度的增加降低了黄瓜幼苗的总生物量，但是对于在 nWTR 中处理的种子，与在淡水中处理的相比，总生物量增加了。耐盐性和活力指数显着（p < 0.01）受盐度水平、nWTRs 处理及其相互作用的影响。可以得出结论，nWTRs 是盐胁迫条件下植物生长的改善材料。1000 mgL-1引发处理获得了胚根半径的最低值。培养基中盐浓度的增加降低了黄瓜幼苗的总生物量，但是对于在 nWTR 中处理的种子，与在淡水中处理的相比，总生物量增加了。耐盐性和活力指数受盐度水平、nWTRs 处理及其相互作用的显着影响（p < 0.01）。可以得出结论，nWTRs 是盐胁迫条件下植物生长的改善材料。耐盐性和活力指数受盐度水平、nWTRs 处理及其相互作用的显着影响（p < 0.01）。可以得出结论，nWTRs 是盐胁迫条件下植物生长的改善材料。耐盐性和活力指数受盐度水平、nWTRs 处理及其相互作用的显着影响（p < 0.01）。可以得出结论，nWTRs 是盐胁迫条件下植物生长的改善材料。
