There are more than 80% embryoids among the induced masses in anther culture; different ammonium salts produced different effects on the formation of embryoids, and the effect of NH4H2PO4 is better than the others, within the range of the concentrations used. When the combinations of KNO3 With NH4H2PO4 act as the nitrogen source the frequencies of formation of embryoids and calli increase with the increase of NO3–/NH4+ ratio, at NO3–/NH4+ = 6:1, the frequency is the highest, but at 8:1, it decreases. In the treatments of lower total nitrogen (22.5–37.5 mN/L), the induction frequency is higher (3%–12%) than those of higher total nitrogen (45–60 mN/L). It has also been discussed that the different materials responded to the same ammonium salt, that the same material responded to different NO3–/NH4+ ratio.
