The vegetative and reproductive responses to the removal of all pistillate flowers at or just prior to anthesis in the cucumber were studied with the variety Taisen No. 1, and obtained the following results.
1. The vegetative growth was invigorated remarkably by the removal of pistillate flowers.
2. The removal of pistillate flowers increased both male and femalenodes but latter were increased more than former and reduced the ratio of male to female nodes at least 32 per cent.
3. The influence of removing pistillate flowers upon the production of flowers and sex ratios was not exhibited on the main stem. It was displayed on the laterals.
4. The reversal of the effect of removing pistillate flowers on the sex ratio occurred in the last period of growing season.
