Abstract

Macroexplants consisting of two nodes with leaves were prepared by the tip of sprigs of 20 autochthonous cvs in the olive collection of Valias. In addition to Control treatments with IBA 2g/l-1, 5g/l-1, and 8g/l-1 were applied at the beginning of spring. Morphological and physiological exchanges were controlled for the temperature of substrate and environment 24C and 18C and for air humidity 95%, throungh mist propagation method..The results exposed the genetic origin and endogenous predisposition as the beginner of rhizogenesis which fluctuated from 4.6% to 27%. Whereas the auxin increased rhizogenesis 28.7 – 48.9% as per concentrations compared to Control. The cultivars had good callogenesis of 43.6/ 95.4% (5>8>2>0 g/l-1 IBA), whereas rhizogenic capacity was average 14.7/63.6%, conditioned by hormones. Correlation between callogenesis and rhizogenesis was considerably good for cv. Kushan, Kaninjot, Freng (r²=0.93) and average for cv Kotruvsi, u Kuq, Mixan etc (r²=0.55). Maximum per rooting was 95.2% whereas the number of adventives roots was 8.8 At this phenophase of meristematic development use of dosage 5g/l-1 is more justifiable than with the two other concentrations ofIBA and Control (r²=0.94).
