Environmental stress leading to a decrease in growth may be compensated for later in ontogeny by a growth plastic response. Such response could be also transmitted to the next generation, which is called transgenerational plasticity. In this study, two Plantago species were used to test whether compensation for biomass loss after disturbance is driven by maternal effects (ME) due to nutrients and disturbance, i.e. by the form of transgenerational plasticity. Additionally, we tested whether ME could contribute to a different performance of progeny having different disturbance histories. We also tested whether ME are adaptive and whether they differ between related species. According to our results we conclude that compensation for biomass loss is driven both by maternal effects and by progeny environment. This may lead to the different success of regenerative strategies in environments with contrasting nutrient levels.
