1. As the material the Japanese radish was used.
2. Retardation of the growth of the growing point by embedding in gypsum causes flower-initiation to some extent, though the plant is not exposed to cold.
3. Retarding the growth of plumule by application of malefic hydrazide solution to it, causes flower-initiation in some measure, though the plant is not subjected to low temperature.
4. Inhibition of vegetative growth by using hypertonic sugar solution leads to flower-initiation in some degree, in spite of no cold-treatment.
5. The writers advance a speculation that the aging of the protoplasm in the tissue of the growing point is probably favourable to inducing flower-initiation.
