IN VITRO ROOTING OF DIFFERENT PEACH GENOTYPES |
| Authors: | M. Antonelli, A. Chiariotti |
| Abstract:
On explants of two peach genotypes: the nectarine cv May Fair ad the semidwarf peach selection IF 7010200E, phloroglucinol, activated charcoal, light and temperature were tested as factors influencing the rooting ability. The two genotypes showed a different response to the auxins (IAA, IBA and NAA): cv. May Fair reacted to all three, while on the contrary the selection IF 7010200E reacted to IAA only. The best results were obtained with one week of pretreatment at 5°C in the darkness. The use of phloroglucinol and activated charcoal strongly inhibited rooting, even in the presence of the auxins. | |
