The research aimed at investigating the biological value of pepino (Solanum muricatum Aiton) fruit at different stages of its ripeness, depending on the growth cycle. Plants from 6 different pepino clones were cultivated on rockwool in a greenhouse in the spring-summer and autumn cycles in the years 1998-2000. Fruit at two stages of ripeness (mature-green and ripe) was collected for analyses. The biological value of pepino fruit depended on the growth cycle, stage of ripeness, and clone. Higher value was observed in the fruit from the spring-summer cycle than from the autumn cycle, mainly in respect to their content of vitamin C. Plants cultivated in the spring-summer cycle fruit containing much more vitamin C - mean for clones 61.3 mg% than plants cultivated in the autumn cycle, the fruit of which, on the average, contained 24.8 mg%. Mature-green fruit contained less dry matter, soluble solids content (SSC), and nearly a half less vitamin C as compared with ripe fruit. However, the content of mineral components in mature-green fruit was relatively high, with the exception of potassium.
