“…Generally, after germination, seedling establishment and growth are characterized by morphological and physiological elongation of coleoptile followed by elongation of the first leaf and radicle which culminates into growth of the embryonic axis. Coleoptile and first leaf form the plumule which is the growing point of the shoot, while coleorhiza and radicle form the growing point of the root (Arteca, 1995). Reduction in the root length and coleoptile from aged hybrid seeds by approximately half signifies that the damaged hybrid seeds when planted will have uneven emergence and poor seedling establishment.…”

Hybrids and open pollinated varieties (OPVs) are two commercial maize seed types cultivated in Nigeria. Information on their response to mechanical damage during processing is limited. This study is thus aimed at assessing the response of hybrids and OPVs of maize seeds to mechanical damage which would facilitate fabrication of processing facilities suitable for either of the maize types. Six maize varieties: three hybids (‘New Kaduna’, ‘SDM-1’, and ‘JO-195’) and three OPVs (‘Sammaz 15’, ‘Sammaz 27’ and ‘Suwan-1-stry’) were used for the study. The seed samples were subjected to standard germination, seedling vigour analysis, accelerated ageing, conductivity and fast green tests. The result showed that all the hybrid seed varieties had more damaged seeds than their OPVs counterpart. Shoot length and root length were more affected than other parts of the seedling. There were differences in the magnitude of electrolyte leakage as well as in what time each seed type (hybrid or OPVs) passed through the phases with ‘JO-195’ having the highest rate of electrolyte leakage. Hybrid seeds had lower resistance to mechanical damage and poorer storability when compared with the OPVs. In the overall, for all the traits, ‘Sammaz 15’, the best among OPVs was more promising when compared with ‘SDM-1’ which was the best among hybrid varieties. Processing machine equipment and accessories that are suitable for hybrid seeds might be inappropriate for conditioning OPVs.

We propose an in-liquid plasma technique-Solution Plasma (SP)-to help enhance seed germination. Tomato and rice seeds are selected as representatives for dicot and monocot plant seeds, respectively. The effect of SP treatment time on the seed surface's chemical morphology and wettability is investigated. Compared to the untreated seeds, surface erosion of both seeds is observed. The surface wettability is also enhanced. The SP helps improve the seed germination rate and seedling growth of both seeds.We present the effect of plasma on seed germination in the aspect that SP can degrade polysaccharides-the main constituent of the seed coat. The formation of reactive oxygen species during treatment is supposed to be another reason for better seed germination.
