Description
Lucerne (Medicago sativa) was sown at increasing distances from isolated adult plants along 4 radials 0.5 m long, to evaluate possible influences of the parent plant on seed germination and seedling survival. Time of sowing was also considered with radials 3 & 4 being sown in May and radials 1 & 2 being sown four weeks later. Two cultivars were used in the 1995 experiment; Hunterfield, a winter active cultivar and P545, a winter dormant cultivar. The results indicate that seeds as close as 2.5 cm to established plants could germinate, survive and become established. Observations suggested that the winter activity of the plant had a marked effect on seedling recruitment as did time of sowing.
