“…Thirdly, maternal N addition increased offspring biomass, which indicated that survival seedlings were more vitality. It confirmed previous studies2240 that bigger seed increased seedling performance. Impact of maternal N addition resulted notable intraspecific variation of seed size29.…”

Plants adapt to environment by plastic growth which will be transferred to offspring through transgenerational effect. Performance and response of maternal and offspring plant will affect population dynamics and community composition. However, it is scarcely understood how maternal nutrient environment affect the performance and response of offspring through transgenerational effect. Here we studied the impacts of nitrogen (N) and phosphorus (P) enrichment on maternal and offspring performances and responses of Stipa krylovii and Artemisia frigida. Seeds were collected from maternal plant experiencing N or/and P addition for three years in Inner Mongolia grassland. We found that maternal nutrient addition significantly affected seed traits, offspring biomass, and offspring responses of A. frigida. Maternal N addition significantly affected maternal reproductive biomass, seed traits of S. kryloii. Maternal P addition of S. kryloii significantly affected seed qualities, seedling biomass and seeding response to N addition. Our results suggested that transgenerational effects of N and P enrichment to the two dominant plant species existed in this ecosystem. Furthermore, the two species exhibited different adaptive strategies to future nutrient addition. These findings indicate that maternal environmental effect should be considered into the model projection of vegetation dynamics in response to ongoing environmental change.

“…A better understanding of how plant invaders colonize and establish in new areas is therefore critical to prevent further invasion. However, to date, just a few studies have examined the influence of seed variation and its consequences for plant invaders (Sõber and Ramula, 2013;Susko and Lovett-Doust, 2000).…”

a b s t r a c tSeedling performance can determine the survival of a juvenile plant and impact adult plant performance. Understanding the factors that may impact seedling performance is thus critical, especially for annuals, opportunists or invasive plant species. Seedling performance can vary among mothers or populations in response to environmental conditions or under the influence of seed traits. However, very few studies have investigated seed traits variations and their consequences on seedling performance. Specifically, the following questions have been addressed by this work: 1) How the seed traits of the invasive Ambrosia artemisiifolia L. vary among mothers and populations, as well as along the latitude; 2) How do seed traits influence seedling performance; 3) Is the influence on seedlings temperature dependent. With seeds from nine Western Europe ruderal populations, seed traits that can influence seedling development were measured. The seeds were sown into growth chambers with warmer or colder temperature treatments. During seedling growth, performance-related traits were measured. A high variability in seed traits was highlighted. Variation was determined by the mother identity and population, but not latitude. Together, the temperature, population and the identity of the mother had an effect on seedling performance. Seed traits had a relative impact on seedling performance, but this did not appear to be temperature dependent. Seedling performance exhibited a strong plastic response to the temperature, was shaped by the identity of the mother and the population, and was influenced by a number of seed traits.

“…The overall negligible effect of competition on the establishment of L. polyphyllus in the present study could be partly due to the favourable conditions in the greenhouse, which enabled seedlings to establish even under conditions of strong interspecific competition. On the other hand, the seedling establishment and population growth rates of L. polyphyllus are robust to habitat type and soil pH (Sõber and Ramula, 2013;Ramula, 2014) and therefore, it is possible that interspecific competition has a minor effect on the invasion success of this species also in the field. However, it should be noted that our greenhouse experiment focused on seedling competition, which is restricted to the situation where plants (regardless of their invasiveness status) are colonising open microsites from seed and does not necessarily apply to other types of interspecific competition.…”
