| Popis: | Emerging primocanes of red raspberry, Rubus ideaus L. ‘Boyne’, were sprayed with naphthaleneacetic acid (NAA) at concentrations of 0.5, 1.0, and 1.5% when shoots were 7–13-cm-tall or at 1.0 and 2.0% when they were 13–20-cm-tall. Treated primocanes exhibited leaf cupping and epinasty followed by withering and death. Untreated floricanes and primocanes emerging after treatment were normal. Treatment with NAA at all rates restricted the height of primocanes emerging after treatment. Fruit yield the year following was reduced by NAA applied to shoots 13-20-cm-tall. |
