S ummary .1 Data are given showing that the process of enriching the atmosphere with carbon dioxide affects the tomato plant slightly in many different ways, the sum of these tending to an increased yield of fruit. 2 These effects include (1) shortening of the period between opening of the flower and picking of the fruit, (2) high percentage of blossom developing into fruit, (3) lower percentage of fruit retarded in ripening,(4) better development of the truss normally most poorly developed,(5) earlier development and ripening of trusses in the later part of the season, (6) better swelling of the fruit at the end of the season. 3 Conclusions are drawn from the data that the results of an increased concentration of carbon dioxide are most beneficial to the plant at periods of low fruit‐production. These periods are discussed as occurring in the life of the commercially grown tomato plant. 4 The greatest percentage increases in weight of fruit of the treated plants over the controls are picked from the trusses which develop at such periods in the life of the plant.In conclusion the writer is indebted to Dr W. F. Bewley, Director of the Cheshunt Experimental Station, and Dr F. G. Gregory, of the Imperial College, for valuable suggestions in connection with the text.
