Evaluation of pollen fertility in pepino (Solanum muricatum Ait.)

Kowalczyk K., Kobryń J., Zieliński W.

The influence of the cultivation time (spring-summer and autumn) and the kind of cultivation (on rockwool and peat) on the fertility of pollen coming from three successive trusses were studied for six different pepino clones. The fertility was defined in vitro as the capacity of pollen for germinating. The average capacity of pollen germination ranged in the studied clones from 10 to 15%. These clones displayed the highest pollen fertility in an autumn cultivation, comparing to a spring-summer one. Higher rate of pollen fertility was observed during a springsummer cultivation on first trusses in most of the clones studied. The pollen of all plants grown on rockwool was more fertile, comparing to the cultivation on peat substrate. High differences in pollen fertility of the clones were obtained.

Key words: clone, cultivation time, rockwool, peat
