This experiment studied the effect of NaN 3 on leaf regeneration and salt tolerance of induced leaf regeneration plantlets. The survival rate, regeneration rate, and regeneration number of induced leaves increased with the increasing NaN 3 concentration. The different concentration of NaCl affected the germination value and relative biological yield of the induced leaf regeneration plantlets. The results were higher than that of control. The injury ratios and injury index were both lower than that of the ...
