Abstract

Abstract (2-Chloroethyl)phosphonic acid (ethephon) applied as a dip at 10000 ppm accelerated the ripening of unripe harvested processing tomatoes for juice. Overall processing yield was increased without adversely affecting juice quality.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
