研究了不同转基因水稻品系（T-99、T-112、T-115 和 T-121）在不同盐度水平（0、50、100 和 150 mM NaCl）下的发芽和早期幼苗生长的反应。评估最终发芽率、发芽率（1/t50，其中t50是发芽50%的时间）和早期幼苗生长。最终发芽率随着盐浓度的增加而受到抑制。发芽所需的时间也随着盐度水平的增加而增加。盐浓度（尤其是 150 mM）也会降低幼苗的生长。根、冠长度、根冠比、根、冠鲜重也随着盐胁迫的增加而降低。与其他转基因品系相比，T-99 和 T-112 在发芽和早期幼苗生长方面表现出更好的性能。
The response of germination and early seedling growth of different transgenic rice lines (T-99, T-112, T-115 and T-121) were examined in different levels of salinity (0, 50, 100 and 150 mM NaCl). Final germination, germination rate (1/t50, where t50 is the time to 50% of germination) and early seedling growth were assessed. Final germination percentage was inhibited with increasing salt concentrations. The required time for germination also increased with increasing salinity levels. The seedling growth was also reduced by salt concentrations, particularly at 150 mM. Root and shoot lengths, root/shoot ratio, fresh weights of root and shoot were also decreased with increasing salt stress. T-99 and T-112 had shown greater performance at germination and early seedling growth as compared to other transgenic lines.
