| Research Abstract |
Basic growth function was combined with its first and second derivatives to form a new equation, which was then investigated to derive its 4-dimensional properties based on analogies with Newton' s law of motion and special relativity. In its application to the growth analysis of an individual forage plant, the squared value of net growth acceleration for plant weight(NGA : growth acceleration for plant weight per unit of leaf area) was calculated for the growth along time axis(t), that along height axis(x), that along width axis(y), and that along depth axis(z). The ratio of NGA squared in 3-dimensional space(the sum of x, y and z) to that in time(t) was considered useful to analyze the process of space structure formation with the growth of an individual forage plant.
