title: Intraspecific variation in the response to CO2enrichment in seeds and seedlings of Plantago lanceolata L.
abstract: Four genotypes of P. lanceolata were grown to maturity at combinations of two levels of atmospheric CO2concentrations and two temperature conditions. Seed weight was determined, and seed germination and seedling growth were measured for the progeny of each genotype under the same environmental conditions. Overall, high CO2levels decreased seed weight, increased germination percentage and rate, and increased seedling size. Families differed in their response to CO2enrichment, and to combinations of CO2and temperature levels for several characters. These results suggest the existence of genetic variability in P. lanceolata in response to CO2enrichment.
