Abstract

The total ascorbic acid contents of four varieties of tomato fruits, Lycopersicum esculentum, Mill were determined.  The ascorbic acid contents of three varieties (Green Shoulder-48--1-2, Uniform Gene-8-1-2-7 and Green Shoulder- 11-3-1) which were growth in the field, increased during the forenoon and decreased in the afternoon.  The ascorbic acid contents of these three varieties were higher during the dry season then in the wet season.

Plants of the College-Strain-48-1 variety grown in the pots.  The fruits from plants grown under the sun had higher ascorbic acid content than the fruits from plants grown in the shade.  A significant drop in ascorbic acid content of the fruits were observed when the plants grown under the sun were transferred to the shade.  On the other hand, a significant increase in ascorbic acid was observed when the tomato plants were transferred from the shade to the sunshine.
