摘要

Purpose

Multi-Walled Carbon Nanotubes (MWCNTs) have been observed to significantly stimulate growth and improve quality in various crops when applied at optimal concentrations. Therefore, this study evaluated the effects of different MWCNT concentrations on the morphological traits, quality attributes, and yield of potato genotypes.

Methods

The experiment was conducted in a Randomized Complete Block Design with two factors, i.e., MWCNTs doses (0 (control), 5, 10, and 15 mg L^-1) and Potato genotypes (21088, 21091, and Actrice), replicated three times. The data on various qualitative and qualitative attributes of Potato genotypes were recorded.

Results

It was observed that MWCNTs significantly enhanced the studied research parameters i.e. enhanced the Plant height, Stems tuber^-1, Stem diameter, leaflets plant^-1, Chlorophyll-a & b contents, Xanthophyll content, Roots plant^-1, Number of tubers plant^-1, Tuber yield plant^-1, Total Soluble Solids (TSS), Vitamin-C, Carbohydrates contents, and reduced days to sprouting and mortality rate, compared to control. In the potato genotypes response to MWCNTs, the maximum mortality rate, plant height, tuber yield plant^-1, TSS, and Vitamin-C were recorded in genotype 21,091. In contrast, maximum Days to sprouting, Stems plant^-1, Stem diameter, Chlorophyll-a, Chlorophyll-b, Xanthophyll, and Carbohydrates contents were observed in genotype Actrice. Moreover, the maximum leaflets plant^-1 and the tubers plant^-1 were recorded in genotype 21,088.

Conclusion

The findings of this study demonstrate that the application of MWCNTs significantly improves growth, quality attributes, and yield in potato plants. Among the tested concentrations, 15 mg L^-1 was identified as the optimum level for enhancing yield across the tested genotypes. Furthermore, the results indicate genotype-specific variability in response to MWCNTs application, highlighting the importance of considering both concentration and varietal differences when optimizing MWCNTs use in potato cultivation.
