Abstract
Plants of three pepino clones, numbers 3, 4 and 6, were grown on rockwool, supplying the nutrient solution as recommended for tomatoes.
Some plants were trained to one main stem, others to two stems.
Plant density was 5 and 2.5 plant per m2, respectively.
During the vegetative period, flowers were treated with Betoxon (NOA) or with 4-CPA. Betoxon was applied in 25 ppm or 50 ppm concentrations and 4-CPA 15 ppm or 30 ppm.
Pepino was cultivated in spring-summer and autumn cycles of the year 2000. At harvest, the total and marketable yields and fruit weight were determined.
The obtained results showed that plants trained to one or two stems in spring-summer cycle gave similar total and marketable yields of fruit.
In autumn growing cycle significantly higher yields in plants trained to one main stem were obtained.
The highest yields were given by clone 6, in both growing cycles.
Hormone treatment of flowers with Betoxon or with 4-CPA significantly increased the total and marketable yields of pepino fruit in spring-summer period, while in autumn cycle that effect was not significant.
However, an early yield of fruit was greater with 4-CPA than with Betoxon.
Both auxins were more efficient in higher concentrations.
