Abstract

The biosynthesis titanium dioxide nanoparticles (TiO2 NPs) on seedling growth, yield, biochemical traits, and their transmission effect over two generations were assessed in bitter gourd cv. Megna 2. Six distinct nanoscale TiO2 concentrations (0, 10, 20, 50, 80, and 100 mg L-1) were applied to bitter gourd seeds, along with a control. Various characterization methods, including dynamic light scattering (DLS), UV–visible spectroscopy, fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM), were utilized to verify the dimensions, absorption spectra, functional molecules and surface structure of biosynthesis TiO2 NPs. The initial study observed that the nanoparticle-treated seeds produced better germination and seedling growth (p < 0.05) than the control. Treatments with TiO2 NPs at the seedling stage had a substantial effect on catalase and peroxidase activities. Parental TiO2 NPs treated seeds ‘N1’ (first generation) and their progeny ‘N2’ (second generation) showed substantial changes in plant growth, fruit yield characteristics, and phytomedicine properties in bitter gourd. Concentration with 80 mg L-1 over the two generations proved to be the best treatment, which significantly increased total chlorophyll content, ascorbic acid content, TSS content, beta carotene content, charantin contents, and cucurbitacin content, respectively, compared to the control. After two generations of verification of TiO2 NP uptake in roots and shoots, it was discovered that the quantity of particle accumulation in the next generation had decreased but significant results achieved for growth and phytomedicinal properties in bitter gourd. These findings suggested that biosynthesized TiO2 NPs can induce stable transgenerational enhancement offering promising applications in sustainable agricultural by improving both productivity and nutritional quality in edible crop plants.
生物合成二氧化钛纳米颗粒对苦瓜生长和植物化学的代际效应
研究了生物合成二氧化钛纳米颗粒(TiO2 NPs)对苦瓜幼苗生长、产量、生化性状的影响及其两代传代效应。Megna 2。将6种不同纳米级TiO2浓度(0、10、20、50、80和100 mg L-1)施用于苦瓜种子,并作为对照。利用动态光散射(DLS)、紫外-可见光谱、傅里叶变换红外光谱(FTIR)和扫描电镜(SEM)等表征方法,对生物合成TiO2纳米粒子的尺寸、吸收光谱、功能分子和表面结构进行了验证。初步研究发现,纳米颗粒处理的种子萌发和幼苗生长较好(p <;0.05)。苗期TiO2 NPs处理对过氧化氢酶和过氧化物酶活性有显著影响。亲本TiO2 NPs处理过的种子N1(第一代)及其后代N2(第二代)在苦瓜植株生长、果实产量特征和植物药物特性方面发生了实质性变化。两代处理中,以80 mg L-1处理效果最好,与对照相比,总叶绿素含量、抗坏血酸含量、TSS含量、β -胡萝卜素含量、charantin含量和葫芦素含量均显著增加。通过对两代苦瓜根和芽对TiO2 NP吸收的验证,发现下一代的颗粒积累量有所减少,但对苦瓜的生长和植物药用性能均有显著影响。这些发现表明,生物合成的TiO2 NPs可以诱导稳定的跨代增强,通过提高可食用作物的生产力和营养质量,在可持续农业中具有广阔的应用前景。

期刊介绍: The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
