Résumé :
|
[Populations of Lolium perenne were sown at a wide range of densities and allowed to develop without defoliation under full daylight and under reduced light intensities. The multiplication of tillers, the growth in their mean weight and the death of genetic individuals (genets) acted together to regulate the character of the population and to determine that the density of tillers per unit area became independent of sowing density. The rate of elimination of genets from the population was related to the rate of growth of the survivors according to the 3/2 thinning law, but under low light intensities the thinning process was radically altered in a way that suggests that the density stress within the grass populations was caused by mutual self-shading.]
