Abstract

A greenhouse experiment was conducted ‎to study the influence of the application of four concentrations of silica nanoparticles (NSi) in mitigating the negative effect of salinity shock on ‎cucumber (Cucumis sativus L.). Seedlings were sprayed with NSi ‎ (0, 100, 200, and 300 ppm) as the NSi treatment, and the plants were subjected to either no salinity shock (NSCh) or salinity shock (WSCh) 3250 ppm for two days. Yield and vegetative parameters, K+, Na+, K/Na ratio, Si, and proline contents were measured. The NSi treatments prevented the harmful effects of salinity on yield, with a reduction of 9.19% for plants treated with NSi3 under WSCh compared with NSCh. Salinity shock caused an accumulation of proline in the roots and other plant parts as a method of protection. The NSi2 and NSi3 treatments under WSCh prevented the accumulation of Na+, leading to an increase in the K/Na ratio. The Si contents in the roots, leaves, and fruits increased with increased NSi. The results of the interaction treatments showed a significant ‎effect on all ‎traits except for plant length, leaf area, chlorophyll, and ‎root ‎potassium content.

纳米二氧化硅在改善盐胁迫对黄瓜生长的影响中的作用

通过温室试验，研究了不同浓度二氧化硅纳米颗粒(NSi)对黄瓜(Cucumis sativus L.)耐盐性的影响。幼苗喷施NSi(0、100、200和300 ppm)作为NSi处理，幼苗分别受到无盐胁迫(NSCh)或3250 ppm盐胁迫(WSCh)两天。测定了产量和营养参数、K+、Na+、K/Na比、Si和脯氨酸含量。NSi处理防止了盐度对产量的有害影响，与NSi处理相比，NSi3处理在WSCh下的产量降低了9.19%。盐休克引起脯氨酸在根和其他植物部位的积累，作为一种保护方法。WSCh下NSi2和NSi3处理抑制了Na+的积累，导致K/Na比值升高。根、叶和果实中Si含量随NSi的增加而增加。结果表明，除株长、叶面积、叶绿素和根钾含量外，互作处理对其他性状均有显著影响。
