    The influence of seed size and weight on early seedling growth of tree species has been studied for over 50 years. Righter (1945) found that, in the genus Pinus, the positive correlation between seed weight and seedling height was temporary and disappeared after time in the field. A more recent study with loblolly pine (Pinus taeda L.) has shown a statistically significant positive correlation between seed weight and tree height after 15 year. Khalil reported that seed weight in white spruce (Picea glauca) was positively connected with annual growth of the terminal shoot at 2 and 4 years.
