| Abstract/Contents: | "Patterns of seed dispersal and seedling recruitment of Sorghum halepense (L.) Pers. were compared in abandoned and cultivated fields in Argentina. In both the abandoned and cultivated plots, the greatest concentration of seed fell below, or only a short distance, from the parent plants. A maize combine harvester greatly increased the distance of dispersal of a small part of the seed population. The availability of seed for dispersal, the direction and velocity of wind and the combine harvester were important factors determining the temporal and spatial patterns of seed distribution. The ratio of recruited seedlings to seeds shed was only 1% under the parent plant, but increased to about 100% at a distance of 1 25 m. Soil tilling, which is required for seedling recruitment, and seed density were important factors in determining seedling density as the distance from the parent plants increased. The rate of seedling recruitment was higher in areas where most of the seeds were dispersed late in the season than in those where dispersal occurred early." |
