Abstract
The importance of temperature experienced during seed maturation (maternal environment) and during germination and seedling growth (progeny environment) on seed and seedling characters was examined in 4 maternal half-sib families of P. lanceolata. High maternal temperatures decreased seed weight and increased the percentage germination and an index germination rate. Families of P. lanceolata responded to the maternal and progeny environments in different ways. The effects of the maternal treatments on seed wt, percentage germination, and an index of germination rate were detectable in a 2nd generation.
