Growth analysis of Scots pine (Pinus sylvestris L.) seedlings cultivated in a wide range of experimental conditions

Abstract

The work of this laboratory for many years with Scots pine seedlings has allowed to collect quite unique information as to the accumulation and distribution of dry matter and the reaction of plants to various environmental influences. It seems worthwhile to publish the main experimental data almost in extenso because they may be used in future work for building mathematical models of plant growth. The presented experimental data enabled to discuss controversial points of quantitative analysis of plant growth such as: the time instant and the initial value of growth to be taken as the starting points (t0 W0); exponential approximation of the growth curve; inadequacy of allometric approach in modelling vegetative growth of plants, etc. The discussion aims at defining more closely the essential notions of growth analysis.
