The experiments with water as only limiting factor was designed to study the dynamics of size inequality in spring wheat ( Triticum aestivum L.)populations and its theoretical basis.Of the three density (low,medium,high)wheat populations,the skew( G ) of weight distribution of wheat plants increase with time,and the increase rate is the highest in high density population.The author determined and compared the water absorbing power,transpiration rate,photosynthetic rate of different size...
