AB  - High variability in somatic embryo (SE)-forming capacity has previously been observed in several spinach cultivars. Such variability frequently accounted for more variation in embryogenic response of the explants than the factor being investigated. Hence, the variability in embryogenic capacity was examined in the present study at both the population and the single-seedling level, using seeds of spinach cultivar Matador obtained from nine European seed companies. Seed population obtained from Slovenia (Sl) was superior to others, with the highest regeneration frequency (100%) and the highest mean SE number (14.4). A total of 82% of these seedlings had 80-100% of regenerating explants, while in populations with intermediate embryogenic capacity approximately 40% of seedlings had 20-60% of regenerating explants. The explants from the majority of seedlings (52-100%) in the least responsive populations were irresponsive. Furthermore, the explants from Sl seedlings regenerated from 10-20 (43.5%) up to>20 (27.6%) SEs on average, while the explants from the majority of seedlings belonging to other populations regenerated 1-10 SEs. The present study strongly indicates that the variability of plant material must not be overlooked, because choosing more responsive individuals for one treatment and less responsive ones for another may lead to misinterpretation of the data.

AB  - As has been previously shown, the genotype at the individual plant level has a strong effect on the regeneration capacity of spinach, and this effect quite often masks the impact of other factors, including the light environment. Therefore, apical sections of the lateral roots of the same seedling (line) were exposed in parallel to both long day (LD, 16-h photoperiod) and short day (SD, 8-h photoperiod) conditions to assess the effect of photoperiod on somatic embryo (SE) regeneration. The root sections in most lines responded with significantly higher frequencies of regeneration and mean SE numbers with LD compared to roots of the same origin with SD. while 7 of 40 lines were only able to regenerate when exposed to LD. Moreover, in all lines cultured with SD, regeneration was delayed by approximately 4 weeks. Obtained SEs were further grown and multiplied, providing material for the evaluation of the effect of light intensity on regeneration capacity. Maximal regeneration capacity was recorded at 100 mu mol m(-2) s(-1) in all lines tested. The present research confirmed the previously observed strong effect of genotype on regeneration capacity and undoubtedly showed a significantly better response in explants exposed to LD than to SD. These results could contribute to better understanding the process of SE induction in spinach and further improve the efficiency of this process.
