  abstract = {{T}his paper presents some of the effects of cryopreservation of wild {S}olanum lycopersicum {M}ill. seeds on the early stages of germination post liquid nitrogen exposure. {P}ercentage of germination, conversion into plantlets and plant fresh mass were evaluated after cryostorage. {L}evels of chlorophyll pigments (a, b, total), malondialdehyde, other aldehydes, phenolics (cell wall-linked, free, and total) and proteins were determined. {P}eroxidase and superoxide dismutase activities were recorded. {L}iquid nitrogen exposure increased the percentage of seed germination at 5 days but at 7 days, the conversion into plantlets and the plant fresh mass were not statistically different between non-cryopreserved and cryopreserved samples. {S}everal significant effects of cryopreservation were recorded at the biochemical level at 7 days of germination under controlled conditions. {H}ighly significant effects due to liquid nitrogen exposure were observed in leaves: increased levels of peroxidase enzymatic and specific activities and cell wall-linked phenolics. {V}ery remarkable effects were also recorded in roots: decreased contents of chlorophylls and cell wall-linked phenolics.},
