تأثير طول القلم و إندول حامض البيوتريك و بيروكسيد الهيدروجين في تجذير صنفي الزيتون Olea europaea L. بعشيقة و منزينللوا

Abstract EN

This study was carried out at wooden sunblind belongs to the plantation Kirkuk Directorate of Agriculture / Ministry of Agriculture in the period from 1/11/2014 to 01/02/2015 to study the effect of length of cutting and treatment by (IBA) and hydrogen peroxide in the success rate of two variation of olives (Menzinelloa and Ba'shiqah) olive cuttings were taken from the plantation of Ain Kawa-Erbil had immersed in pesticide innate cutting for 5 minutes and then was treated after being dried with different concentrations of (IBA) and hydrogen peroxide and planted in the center of proliferation.

The study factors have included two types of olive Ba’shiqah and encoded with V1 and Menzinelloa encoded V2 .

The second factor is the length of the cuttings and including three lengths (5.10: 15) cm and the symbol of a symbol (L1, L2 and L3) sequentially and the third factor they transactions rooting included the comparison and IBA (1000).

mg .

g -1 and 3000 mg .

g -1 and hydrogen peroxide concentration of 4% and its code (T0, T1, T2 and T3), sequentially.

Carried out the experiment as an experiment global as randomized complete design as it included the experiment three factors with three replicates and eight cuttings per each replication Data were analyzed statistically according to the program Genstat and compared to the averages by testing least significance differences (LSD) at the 5% level and the results could be summarized as follows: The results showed not significance effect of variation olives on all study characters.

Vegetative growth characters increasing when using the cutting length 15 cm wich gave the highest rate of the number and length and diameter of vegetation and the, number of leaves, as was (1.431 vegetative growth , 2.25cm, 1.7311mm and 5.63 leave).

while less than the length of the cutting 5 cm in the highest rate of the number and length and diameter of vegetation and the, number of leaves, as was (1.004 vegetative growth , 1.11cm, 1.055mm and 3.33 leave) respectively.

While given the length of cutting 10 cm higher rate to the percentage of rooting and number of roots, with(36.8%, 4.10 reached the root) respectively.

As for rooting treatment, the results showed the superiority of the treated by IBA (3000) mg.gm-1 on the other in the character of the percentage of rooting cuttings and the number and length and diameter of the roots and which was (56.1%, 7.24 Root, 10.10 cm and 1.26 mm), respectively, either treatment by hydrogen peroxide has significantly exceeded in the highest rate of percentage of cuttings of vegetative growths constituent as it was (72.4%) while control gave less rate of percentage of cuttings of vegetative growths constituent as it was (41.3%) .

Triple interaction showed significant differences where V1L2T1 gave the highest percentage of the rooting cuttings and the number of roots and weight soft roots as the percentage (73.3%, 13.33 root and 3.197 g) , respectively, and treatment V1L3T1 gave highest rate of root length and dry weight of roots was (19.67 cm and 0.893 g) , respectively, while the treatment V2L3T2 gave highest percentage of cuttings vegetative growths constituent and number of leaves, amounting to (88% and 8.67 leave) , respectively.
