Abstract
SUMMARYThe growth of Impatiens parviflora DC. under four temperature regimes (13°C, 16°C, 20°C and 23°C) and a constant 18 h photoperiod was analysed using the traditional methods of growth analysis. Temperature had a very marked effect upon the growth rate, but the net assimilation rate was not markedly temperature‐dependent. The results are discussed in the context of previous work on I. parviflora, notably that by Evans and Hughes in respect of light intensity and also in the light of a simple model presented by Warren Wilson (1972), in which the main growth analysis parameters were related to source and sink activities in the plant.
