Abstract

This study aimed to investigate the effect of nanoparticles and non-nanoparticles of titanium dioxide on germination indices of Echinacea under salinity stress. Experimental treatments included nano and bulk particles of titanium dioxide at concentrations of 0, 10, 50, 100 and 150 mg/l and salinity stress from NaCl at levels of 0, -3, -6 and -9 bar. The results showed that Echinacea is sensitive to high salinity stress levels (-6 and -9 bar). The use of nano and non-nano titanium dioxide treatment improved some traits under severe salinity stress. The germination percentage did not occur at salinity levels of -6 and -9 bar, but the addition of nano titanium dioxide with a concentration of 150 mg/l and 50 mg/l non-nano increased germination by 50.6%. Application of nano titanium dioxide increased the seedling weight in control by 1.28 mg to 4.26 mg in the treatment of 150 mg/l nanoparticles. The application of nano and bulk titanium dioxide could significantly reduce the negative effect of high salinity stress levels. This can be a valuable and hopeful solution to solve the problem of salinity stress in Echinacea.

二氧化钛纳米颗粒和大块颗粒对紫锥菊种子和幼苗盐度胁迫的缓解作用

本研究旨在研究纳米二氧化钛和非纳米二氧化钛在盐度胁迫下对紫锥菊发芽指数的影响。实验处理包括浓度为0、10、50、100和150 mg/l的二氧化钛纳米颗粒和大块颗粒，以及来自NaCl的盐度应力水平为0、-3、-6和-9巴。结果表明，紫锥菊对高盐度胁迫水平（-6和-9bar）敏感。纳米和非纳米二氧化钛处理改善了严重盐度胁迫下的一些性状。在-6和-9巴的盐度水平下，发芽率没有发生，但添加浓度为150毫克/升和50毫克/升的纳米二氧化钛使非纳米的发芽率提高了50.6%。在150毫克/l的纳米颗粒处理中，纳米二氧化钛使对照的幼苗重量增加了1.28毫克至4.26毫克。纳米二氧化钛和大块二氧化钛的应用可以显著减少高盐度应力水平的负面影响。这对解决紫锥菊的盐度胁迫问题是一个有价值和希望的解决方案。

期刊介绍： Advances in Horticultural Science aims to provide a forum for original investigations in horticulture, viticulture and oliviculture. The journal publishes fully refereed papers which cover applied and theoretical approaches to the most recent studies of all areas of horticulture - fruit growing, vegetable growing, viticulture, floriculture, medicinal plants, ornamental gardening, garden and landscape architecture, in temperate, subtropical and tropical regions. Papers on horticultural aspects of agronomic, breeding, biotechnology, entomology, irrigation and plant stress physiology, plant nutrition, plant protection, plant pathology, and pre and post harvest physiology, are also welcomed. The journal scope is the promotion of a sustainable increase of the quantity and quality of horticultural products and the transfer of the new knowledge in the field. Papers should report original research, should be methodologically sound and of relevance to the international scientific community. AHS publishes three types of manuscripts: Full-length - short note - review papers. Papers are published in English.
