A SEMIAUTOMATIC METHOD FOR MEASUREMENT OF SEEDLING LENGTH

A method for the measurement of seedling length is presented here. Han d-drawn images of seedlings are converted into numerical files and pro cessed further by the computer to obtain length approximations based o n intercept measurements. Error assessment is performed based on measu rement replications. The numerical results obtained on examples show t hat the errors are rather small compared to the biological length vari ation of seedlings. The high speed of measurement, the simple construc tion of this system and its fidelity make it very attractive for the a cquisition of this type of data.
