Germination and seedling growth of soybean (Glycine maxL.) cv. Williams were examined on paper towels pre-moistened with a range of saline solutions (germination: 0–500 mMolal NaCl; seedling growth: 0–330 mMolal NaCl). The Na+, K+and Ca2+concentrations in the embryonic axis immediately before germination and in the seedling 3.5 d after germination were measured. Germination decreased at NaCl concentrations of 330 mMolal (81% germination) and above. At 420 mMolal NaCl, only 40% of seeds germinated, and at 500 mMolal NaCl there was no germination. Seedling growth rate decreased drastically with increasing salinity. At 220 mMolal NaCl, seedling growth rate had declined to 5% of the control, whereas at 330 mMolal NaCl seedling growth was almost zero 3–4 d after germination. Thus, soybean seeds were more tolerant of salinity in the germination than in the seedling phase. The results suggest that the greater tolerance of salinity during the germination phase might, in part, be the result of a lower sensitivity to high tissue Na+concentrations. Germination (40%) was possible at a tissue Na+concentration in the embryonic axis of 9.3 mg g FW-1, whereas seedling growth was completely inhibited at a tissue Na+concentration of 6.1 mg g FW-1. Germination at higher tissue Na+concentrations was associated with higher K+and Ca2+concentrations in the embryo axis, compared with growing seedlings, suggesting that these ions may protect the seeds in the pre-germination phase against salinity.

Early seedling growth rate can be used to estimate seed vigor for small-seeded vegetable and flower seeds. However, hand measurement of small seedlings is tedious and difficult to reproduce among analysts. Computer-aided analysis digital images of seedlings should improve accuracy and reproducibility. A flat-bed scanner fitted with base and top lighting provided high resolution images of even small-seeded species like petunia [Petunia ×hybrida `Blue Picotee' (Hort) Vilm.] and lisianthus [Eustoma grandiflorum `Mariachi Pure White' (Raf.) Shinn]. Uniform lighting was provided and images were captured and analyzed in less than 2 minutes. A clear, cellulose film was used as the germination substrate in petri dish germination assays to facilitate capturing images with a flat-bed scanner. The transparent medium permitted seedlings to be imaged without removal from the petri dish and also allowed for repeated measures of the same seedlings in order to calculate growth rate. Six species evaluated in this study included cauliflower (Brassica oleracea L., var. Botrytis), tomato (Lycopersicon esculentum Mill. `New Yorker'), pepper (Capsicum annuum L. `North Star'), impatiens [Impatiens walleriana Hook. f. `Impact Lavender'], vinca [Catharanthus roseus (L.) G. Don. `Little Bright Eye'], and marigold (Tagetes patula L. `Little Devil Flame'). For germination and early seedling growth, the cellulose film compared favorably with other standard germination media (blue blotter and germination paper) for five of the six species tested. Computer analysis of seedling length was possible for all six species and was statistically similar to hand measurements averaged for three analysts.

This study was carried out to determine the effect of different NaCl concentrations on germination and early seedling growth of some sugar maize (Zea mays L. sacharata sturt.) Varieties. NaCl was applied to the seeds of Vega F1 (sh2), Merit F1 (su) and Tanem F1 (su) varieties at 0 (control), 2, 4, 6, 8 and 10 dSm -1 concentrations. 5 days after seed sowing germination rate, 12 days after the root length, stem length, stem stem ratio, root dry matter ratio, stem dry matter ratio, seedling power index and salt tolerance were measured. Significant differences were found between the characters examined in the study. As a result; It was determined that germination rate and seedling growth characteristics decreased as cultivars salt ratio increased to different salt concentrations. It has been determined that while the total F1 cultivars have the highest values in terms of germination rate and salt stress tolerance, it has the lowest values in terms of root and stem length and root stem ratio. In terms of seedling power index, Vega F1, Tanem F1 and Merit F1, respectively. According to the correlation results, statistically significant positive differences were found between the parameters examined. It was determined that seed germination and early seedling growth parameters were not affected from the germination environment up to 2 dSm-1 salinity level, while it was found to be negatively affected at 2 dSm-1 high levels. It has been determined that water up to 2 dSm-1 salinity level can be used in sugar corn germination and early seedling development periods in aquaculture areas.
