| Abstract:
Successive harvests were performed in a large number of propagating experiments with tomato seedlings. Various characteristics of the harvested plant material were determined to describe the growth performance of the plants and to describe the change in relative importance of different plant parts during growth. Fresh and dry weight of the total shoot and of leaves separately were determined over a wide range of growing procedures and of greenhouse conditions. Dry matter production can be satisfactorily determined by fresh weight measurement, both for shoot and leaves. Also the amount of leaf material can be determined from its relation with total shoot fresh weight. It seems that the relation between characters can only be properly described by the slope of the functions and not by relative percentages, unless one is sure that the curve passes through the origin. | |
