Randomized trial evaluates carbon nanotube and hydro-priming effects in pea seeds, suggesting advanced non-destructive analysis methods.

The aim is to assess how carbon nanotube and hydro-priming affect pea seed germination using advanced imaging techniques.
Utilized 4D swept-source optical coherence tomography (OCT) for volumetric imaging of seeds.
Performed biospeckle analysis to quantify internal seed activity and structural changes.
Conducted chlorophyll fluorescence measurements for comparative assessment of biological activity.
Carbon nanotube primed seeds exhibited higher temporal speckle activity compared to unprimed controls.
OCT effectively distinguished between treated and untreated seeds through enface and axial scans.
Chlorophyll fluorescence provided insights but was less effective than OCT in discerning treatment effects.

Viqar et al. (2026) studied this question.
