Intraspecific variability and maternal effects in the response to nutrient addition in Chenopodium album

Intrapopulational variability in the response to nutrient addition was studied in plants, of the widespread annual weed Chenopodium album L. Five seed 'families' (each the progeny of a single individual) were selected at random from a natural population, and the germinated seeds were grown...
