Abstract
Photiniaspp is part of the Rosacea Family, evergreen bushesand shaded red in early growth. The experiment was conducted in the private greenhouse in Laknas, Tirana. On February 2015 pieces of Photinia were taken from the upper part of the mother plants. These pieces were cut at 10-12 cm length and a diameter of 0.2-0.5cm. The pieces are placed on the rooting bank with 100% perlite.The pieces are treated before putting them to the rooting bank with phyto-hormone IBA (Indole Butyric Acid) an industrial powder “Germ” by growing 3 variants; Variant 1-2000 mg/l IBA, Variant 2-3000 mg/l IBA, Variant 3-4000 mg/l IBA. Besides the evaluation of the percentage of rooting, 3 measurements are performed at equal time intervals for: the length of seedlings, seedling diameter, root length, number of leaves, length of leaves, etc. For each variant it is also measured the dry weight of the stems and leaves of seedlings and dry weight of root system that is a very important element to show the preparation of the seedling to be transferred to the vase. At the end of our experimental work it is very important to evaluate what concentration of phyto-hormone has greater impact on the development of the seedling root system.So as a conclusion we can say that treatment with IBA 3000 and 4000 mg/l have a powerful impact on the development of the root system of Photinia x fraseri “Red Robin” than treatment with concentration 2000 mg/l IBA.
