Genotypic Differences Between Some Clones of Aborescens Willows in Respect to Ability of Adventitious Roots Formation — Important Factor of Early Diagnosis in Selection Summary From the 21 clones, cuttings in the water culture have been investigated in the respect of genotypic differences concerning the time of adventitious roots formation, as well their number, enght and weight performance. It -was also estimated the correlation between the number of adventitious roots and production as well as survival on experimental plots with the aim to establish the possibility of early selection with regards to these properties. The results have shown the following: 1. Genotypic differences were found between the investigated clones concerning the time of adventitious roots formation as well their number, lenght and weight performance. Differences were not only found between the clones belonging to different species and hybrids but also between the clones belonging to different provenances. 2. Positive significant correlation between the number of adventitious roots and productivity, as well the number of adventitious roots and survival was found for the same clones in the experimental plots. 3. Justified statistically significant correlation between the number of adventitious roots and productivity as well survival of the same clones in the field experiments make possible an early diagnosis in selection what significantly reduce the time for valorization the clones in the field experiments. |
