CORRELATED CHANGES IN PLANT SIZE AND NUMBER IN PLANT POPULATIONS.

The article presents a study on thinning in plant populations. It mentions that plants in natural environments survive through phenotypic plasticity and are prone to dying before reproduction. It discusses studies on the density-related mortality and the finding that the survival of plants is related to their weight. The study involves the growing of radish and rape cultivars in pure populations and in soils of varying fertility. Harvests were taken at different periods in seventeen weeks. An overview of the results is provided.
