Abstract

Abstract It is challenging to plant lavender outside of suitable conditions. This economically important plant requires optimal conditions to germinate and produce a high yield. To increase the quality of this plant, tissue culture is utilized. The most problematic aspect of lavender micropropagation is that cytokinin (CK) causes hyperhydricity (HH) during the shooting process. Consequently, this study was conducted to resolve HH in micropropagated lavender plantlets. Different concentrations of silver nanoparticles (AgNPs) were applied in conjunction with 1.0 mg L-1 6-benzylaminopurine (BA). Then, the performance of HH, growth and development, as well as total phenolic (TPC) and total flavonoid (TFC) content, were evaluated. The application of 20 mg L-1 of AgNPs was found to be the optimal method for halting HH. Although shoot proliferation was lower than in BA-supplemented media-grown plants, adding this concentration of AgNPs improved shoot and root quality. An increase in secondary metabolites and antioxidant activity may have caused the remedy of HH.

银纳米粒子消除了微繁薰衣草的过水现象

摘要:薰衣草在不适宜的条件下种植具有挑战性。这种经济上重要的植物需要最佳的发芽条件和高产。为了提高该植物的品质，采用了组织培养。薰衣草微繁最成问题的方面是细胞分裂素(CK)在开花过程中引起过水(HH)。因此，本研究对薰衣草小苗中的HH进行了测定。不同浓度的银纳米颗粒(AgNPs)与1.0 mg L-1 6-苄基氨基嘌呤(BA)一起应用。然后，对HH、生长发育性能、总酚(TPC)和总黄酮(TFC)含量进行评价。应用20 mg L-1 AgNPs是抑制HH的最佳方法。虽然与添加ba的培养基相比，添加此浓度的AgNPs提高了植株的茎和根质量。次生代谢物和抗氧化活性的增加可能导致HH的治疗。
