S ummary1 The growth curves obtained by plotting successive fresh as well as dry weights are of the usual sigmoid type. The percentage of dry matter is the highest in young fruits and thereafter declines and remains fairly constant during maturity and ripening of fruits. The respiration curve during the growth of the fruits shows two high values separated in time: one is initial and represents a high rate of respiration in young fruits, while the other occurs at the onset of senescence. 2 Irrespective of the stage of ripening at picking, winter‐grown tomatoes show the usual “climacteric” rise during the colour change from orange to red. In certain tomatoes there was no evidence of the occurrence of the climacteric, though the sequence of colour change from green through yellow and orange to red was of the usual type. 3 The storage life of the fruits is longest at 5·7 followed by 9·8 and 14·7°C. At a given temperature the storage life is longest in fruits picked green as compared to those picked in the yellow and orange stages. 4 The respiration curves obtained in fruits after transference from low to high temperatures are divisible into two parts: (i) high R.Q. associated with a rapidly falling respiration intensity, and (ii) a value of R.Q. approximating to unity accompanying either a falling or a steady respiration rate.
