Abstract

In this study, the impact of different sources of carbon, ABSCISIC ACID (ABA) – alone and in combination with POLYETHYLENE GLYCOL (PEG) in different concentrations – on the percent of early embryos responding to the secondary embryo (SE) induction and the average number of SEs in each early embryo within Global, PF704, and Option cultivars was analyzed. Exploring the average interactions between the embryos responding to SE induction indicated that the 0.2 and 0.3 M sorbitols induced the highest SECONDARY EMBRYOGENESIS percentage (SE%). With respect to the average number of the induced SEs on MDE, the 0.3 M (300 mOsml-1) glucose in Option cultivar had the highest number of SEs and the fructose in all concentrations produced the lowest number of SEs per MICROSPORE-derived embryos. An increase in the concentration of the ABSCISIC ACID left a negative impact on the induction of SEs. The 0 mM concentration (control) produced the highest number of SEs. With respect to the maturation trait of the SEs on early embryos, it was observed that the ABSCISIC ACID left a positive impact on the three cultivars. The variance analysis of the impact of PEG and the ABSCISIC ACID on the average number of induced SEs of the Option cultivar demonstrated significant differences between the simple effect of PEG and the interaction effects of PEG and the ABSCISIC ACID at P<0.001 and 0.01, respectively. The simple effect of the ABSCISIC ACID was not significant. In addition, the effect of PEG and the interaction effects of PEG and the ABSCISIC ACID on the maturation of SEs was significant at 0.1 and 0.5% confidence intervals, respectively. Comparing the mean of different levels of PEG with the mean of the number of induced SEs/MDE in Global cultivar indicated that PEG had a negative impact on SE induction and reduced this trait.
