NURSERY RUNNER PLANT PRODUCTION, FRUITING AND BEHAVIOUR OF MICROPROPAGATED STRAWBERRY PLANTS

In all the cultivars both the number of stolon filaments and the number of plants, produced by micropropagated mother plants, have always been significantly higher than those of never micropropagated plants. The division into classes, based upon crown diameter, evidentiates that both first quality and second quality plants have a higher number of runner plants in the micropropagated ones.

The cultivar Gorella, using micropropagated mother plants for the production of fruits, had a poor crop. For all the cultivars a certain tendency to late ripening has noted. The daughter plants, derived through successive reproduction from micropropagated mother plants, have had a tendency to produce more fruits than standard plants (i.e. never micropropagated). This fact has been confirmed also using plants of two successive propagations with different planting dates in the cultivar Gorella. Other characters like the average fruit weight, the number of crowns per plant have been checked.
