Abstract
A non-destructive, simple and accurate method of determining the relative growth rate (RGR) of the packed cell volume (PCV) of plant suspension cells in one Erlenmeyer flask at any time during the incubation period is described. The Erlenmeyer flask was tilted and the length of the chord formed by the surface of the packed cells across the bottom of the flask was measured. The chord length and the log PCV were correlated in a calibration line. The method enables the RGR during the exponential growth phase to be calculated by multiplying the slope of the linear part of the curve of the chord length in time with the slope of the calibration line. In order to investigate other growth parameters and to analyse the accuracy of the method statistically, a four-parameter function for the chord length and a computer program were used.
The RGR during the exponential growth phase of cell suspensions of Solanum tuberosum and Haplopappus gracilis appeared to be independent of the PCV of the inoculum. The method appeared to be sufficiently accurate.
