Abstract:
Several variations of budding and cutting propagation methods
were tested for use with filberts. Both summer budding and chip
budding attempts were generally unsuccessful. However, the results
of employing measures to retard desiccation of buds and increase
callusing rates indicate possibilities for future success. Numerous
sheathing, wrapping and sealing materials for prevention of bud drying
were tested. Budding on current season's wood was employed to
obtain more rapid callusing. Tenting of nursery trees was another
method tried for both reducing desiccation and increased callusing
rate by raising temperature.
Of the several root promoting treatments tested with semi-hardwood
filbert cuttings, it was found that a quick-dip application of
2000 ppm indolebutyric acid gave the highest rooting percentage.
When cuttings were rooted in a high humidity environment, bud survival
was better than when they were allowed to root under an open
mist system. Gibberellic acid₃, N6 benzyl adenine and silver
nitrate were used as foliar treatments to cuttings during the rooting
period but they did not consistently improve bud survival.
