Fig. 4From: Acorn size is more important than nursery fertilization for outplanting performance of Quercus variabilis container seedlingsField performance of Quercus variabilis seedlings in relation to acorn size and fertilization regime used to cultivate the plants in the nursery. a Effects on survival during the first and second years (mean ± SE; n = 100). Means with different letters differ statistically according to Duncan’s test (α = 0.05). Lowercase letters refer to survival at the end of year 1; uppercase letters, survival at the end of year 2. b Effects on stem mass at the end of the second growing season (mean ± SE).
