Feather induction by growth regulators on maiden trees of apple and pear






Acta Horticulturae (34): 117-122

Feather induction by growth regulators on maiden trees of apple and pear

Bioassays of extracts from the upper part of maiden trees of apple Jonathan (which tends to feather naturally) showed that the promoter level decreased during the period of the summer bud break, while the inhibitor level appeared to be small but constant. In R.I. Greening (which does not feather easily) the levels of both promoters and inhibitors were higher and constant during the 5 weeks of the investigation.
