不同盐浓度对棉花胚性愈伤组织增殖、胚胎发生及发育均具有一定的抑制作用；但不同盐浓度对棉花胚性愈伤组织增殖、胚胎发生和发育的影响不同，低浓度时抑制作用软弱，高浓度时抑制作用较强，甚至低浓度的盐对棉花胚胎发生还具有某些促进作用，不同基因型对盐胁迫的反应不同，泗棉３号对盐胁迫的忍耐力较强，其它３个品种较弱。 Different salt concentrations inhibited the proliferation, embryogenesis and development of embryogenic callus of cotton. However, the effects of different salt concentrations on the proliferation, embryogenesis and development of cotton embryogenic callus were different, while the inhibition was weak at low concentration , High inhibitory effect at high concentrations, even low concentrations of salt on cotton embryos also have some role in promoting the different genotypes respond differently to salt stress, Simian 3 on the salt tolerance endurance, the other 3 A weaker species.
