The research was conducted from 1993 to 1997, in the western part of
Poland, at the Experimental Station in Przybroda near Poznań. Three
experiments were carried out under high unheated plastic tunnels and six
strawberry cultivars were studied ‘Elsanta’, ‘Honeoye’,
‘Kent’, ‘Kama’, ‘Real’, and ‘Syriusz’.
In all the experiments each year the mean berry weight was evaluated, this being calculated by
dividing the total yield gathered in the season by the total number of
berries. The studied cultivars differed in the mean berry weight of the
total yield, both among particular cultivars and in particular years.
Depending on the year of the experiment and the cultivar, it ranged from
14 to 4 g. In nearly all experiments, in succeeding years, the average
fruit weight decreased with the age of the examined plants. The largest
fruit usually occurred in the first year and the smallest in the third.
The differences in average berry weight among cultivars exceeded 40% in
one year. In the third year the average berry weight of the total yield
was 30 to 50% lower than in the first year. Every year the fruit of ‘Elsanta’ and
‘Honeoye’ were decidedly the largest, while those of ‘Kama’
and ‘Real’ were the smallest.
