EFFECT OF BENZYLADINE AND BRASSINOLID AND INDOL BUTRIC ACID ON MICROPROPAGATION OF KIWIFRUIT Actinidia deliciosa

Abstract

This study was conducted at the laboratory of Plant Tissue and Cell Culture/ Department of Horticulture/ College of Agriculture/ Diyala University. The objective of this study was to show the effects of some growth regulators on THE propagation of kiwifruit and seedling growth in tissue culture. The results showed that medium free gibberellin exceed in seed germination, experiment showed highest shoot number 4.50 and 4.90 shoot plant-1 and the length of average reached at 3.76 and 3.25 cm on medium supplemented 1, 2 mg l-1 BA. The overlap of IBA with BA in the multiplication nodes in the field with concentration 0.5 mg l-1 IBA with 2 mg l-1 BA increase the number of branches (4.80 branch per plant), while the results of overlap between 2 mg l-1 BA with 0.15, 0.25 mg l-1 BL gave the highest shoot number reached 12.50 and 12.00 shoot per plant and means length reached 4.82 cm in concentration 2 mg l-1 BA. The result of rooting show IBA application at 0.5 mgl-1 gave the highest percentage of rooting to 80%, while the concentration of 1 mgl-1 IBA displayed the largest number, length of the roots reached 6.10 root plant-1, 2.45 cm respectively.
