Abstract:
A laboratory study was conducted to determine the effects of Argel extract on life span and quality of tomatoes in laboratory of plant diseases , Sudan University of science and Technology.
The experiment was arranged in a completely randomized design with three replicates .
Different concentration (100% , 50% , 25% ) were extracted from ginger roots, and then treated to tomato fruits, with an untreated onesas control.
Parameters such as color change, damage , shrinkage (beams ) were measured .
The results showed that the fruits in the control had a complete shrinkage and the fruits were reduced in size after 7 days.On the other hand the treated tomato fruits with the different concentrations of Argelextracts gave different responds. The concentrations (100% and 25%) were completely destroyed after 7 days, while the concentration 50% gavethe best results compared to the other concentrations and the control.The shelf life is extended to reach 10 days. s treated concentration 50% and fruit of witness is higher than the treatment of the concentration of (100% , 25% ) .
