THE RESPIRATORY AND RIPENING BEHAVIOUR OF THE TOMATO FRUIT ON THE PLANT

KENNETH A. CLENDENNING

Open publisher page 12 citations

Abstract

The respiratory behaviour of tomato fruits during their growth and ripening on the plant has been studied in relation to the season and light intensity during growth. Growth was found to be associated with an absolute increase in respiration rate. Fruits of all populations showed a marked rise and fall in respiration rate during ripening. This senescent drift was confirmed in detail by following the respiration of individual fruits ripening while still attached to the plant. Although exhibiting the usual senescent drift as they changed colour, fruits grown in summer cloth house plots showed a consistently lower rate of respiration than that observed in all other populations. It also has been shown that the chief path of gaseous exchange of the mature attached fruit is localized at the stem end.
