Variation in graft compatibility of wild Ficus species as rootstock for common fig trees [Ficus carica)

摘要

Several wild Ficus species were evaluated as rootstock for the fig trees. Graft compatibilities of the fig 'Masui Dauphine' (syn. of'San Piero'J were first compared on 21 species of Ficus genus planted in 700 mL pots. Scion growth at one year after grafting was "smooth" on some species (F. palmata, F. septica, F. pumila, and F. stipulatd), but was "very weak" on all 12 species of subgenus Urostigma. Some grafted trees, which had grown smoothly in 700 mL pots, transplanted into 25 L pots. The growth was "smooth" on F. palmata stock, "weak" on F. septica, and "very weak" on the other species. Fruit production of the trees on F, palmata and F. septica stock during two years after transplanting was similar to trees on control stocks (= 'Masui Dauphine'). The fig trees grafted on F. palmata were also planted in an open field, and grew smoothly for three years but rather more weakly than own rooted trees.
