Abstract
Abstract Broomed branches produced about twice as many twigs as healthy branches and the twigs averaged about 50 percent longer in infected branches. The increased biomass of infected branches was about 2.5 times that of healthy branches. Individual twigs taken from large, broomed branches were about 75 percent longer than twigs from healthy branches, but they had less mass (not including the needles) per unit length than twigs from healthy branches. Even so, there was an apparent tendency for the infected twigs to produce a greater mass per growing season than the healthy twigs. There were more needles on the infected twigs but there was no significant difference in the total needle mass per annual segment. Thus, the mass of the individual needles averaged about 25 percent less than that of the needles from healthy twigs. There was also less needle mass per unit length on infected twigs. Considering the mass of both the twigs and needles together, there was no significant difference between the infected twigs and the healthy twigs per annual growth segment but the infected twigs had less mass per unit length than the healthy twigs.
