RELATIONSHIP BETWEEN TRANSLOCATION OF 1,2-14C-(2-CHLOROETHYL) PHOSPHONIC ACID AND PETIOLE ABSCISSION IN COLEUS PLANTS |
| Author: | H. Veen |
| Abstract:
Ethephon moves down the petiole into the direction of the abscission zone. Using peticle segments it was shown that movement is partly due to the presence of a waterfilm layer around the petiole. Translocation of 14C-ethylene could not be observed. The ethephon-induced petiole abscission appeared to be highly age-dependent. | |
