Summary
1. Experiments are described which are designed to compare diploid and tetraploid tomatoes from the standpoint of growth and total size. The data are treated by analysis of variance.
2. It is shown that tetraploids do not differ consistently from diploids in the total amount of substance produced. Polyploidy interacts in a complex way with the genotype to produce small deviations from a constant growth rate.
3. Tetraploid embryos are about 30 per cent heavier than the diploid, but this advantage is lost during germination.
4. Tetraploids do not differ significantly from diploids in their water content.
5. Heterosis in theF 2 is only due to increased initial weight, and it is of the same magnitude in diploids and tetraploids.
