Abstract


In 1969 year the influence of five retardants (CCC, B995 RW78, RW82, RW85 on tomato varieties ('Maria', 'Fireball' and 'Earliest of All') was tested. It was found that CCC and B985 greatly retarded the growth of these three varieties. The retardant B995 delayed and CCC promoted flowering of tomato plants. In the 'Maria' variety CCC increased and B995 decreased early yield. All five agents had no significant influence of the total yield. All the chemicals had a significant influence on the activity of peroxidase and polyphenyloxidase and the content of nitrates in the tomato fruits, but response of the particular varieties differed.
