Effect of 2,4,5‐T and picloram on the regeneration of blackberry (Rubus procerus P.J. Muell) from root segments

Abstract

Mixtures of picloram and 2,4,5‐T for the control of blackberry (Rubus fruticosus L. agg.)

“…Some sprayoperators use lower rates but this is clearly less effective and may at times stimulate more canes to be formed ( Table 2). Stimulation of suckering of R. procertis by picloram under field conditions has also been reported by Amor (1974) and increased shoot growth on root segments soaked in 10"'° M solutions of picloram has been demonstrated (Richardson & Amor, 1975).…”

Regeneration of blackberry (Rubus procerus P. J. Muell.) from root segments

“…(Amor & Miles, 1974) to form shoots on lateral roots after spraying with 2,4,5-T and to a lesser extent, with picloram (Amor, 1974), is one of the main reasons for the success of this plant as a weed. Experiments by Richardson & Amor (1975) examined the effect of 2,4,5-T and picloram on the formation of shoots on root segments of R. procerus. The experiments reported here examine the effect of temperature on regeneration and the distribution of roots and shoots along the original root segment in order to further understand the factors that control regeneration.…”
