There is inadequate information in the case of rootstock application in pomegra­nate. In this study, propagation of pomegranate was investigated using bench grafting. The experiment was conducted as factorial in the framework of CRD design with three replications. The rootstocks were Rb R2 and R3 and the scions included 'Gorj-e- Dadashi' (Si) and 'Gorj-e-Shahvar' (S2). At the end of experiment, successful callus formation at graft union, bud take percentage (BT), bud take stem length, internodes length and shoot fresh and dry weight were measured. The results indicated that roots- tock influenced all measured characters including bud take and consequently the highest and lowest BT were obtained in Ri and R3, respectively. The interaction be­tween rootstock/scion indicated the highest BT in R3Si and R2S2.
There is inadequate information on the application of rootstocks in the propaga­tion of pomegranate. The aim of this research was to study propagation of pomegran­ate using the stenting method. The experiment was conducted on the basis of a com­pletely randomised design (CRD) with two factors: rootstock (Rj, R2 and R3) and the concentration of indole-3-butyric acid (IBA) (0 and 500 mg/l), in three replications. The rootstocks were 'Gorj-e-Dadashi' (R1), 'Gorj-e-Shahvar' (R2) and 'Gool Safid-e- Ashk-e-Zar' (R3), and the scions were of the cultivarMalas-e-Yazdi. The results indi­cated that rootstock type and IBA treatment influenced bud-take and root formation. The highest bud-take percentage was obtained with R1 in combination with 500 mg/l IBA.
This experimental study was conducted at the Fruit Research Institute, Cacak, Serbia, to determine bud break and callus formation dates, the degree of callus forma­tion, grafting success on day 20 after grafting and overall grafting success on day 28 after grafting in walnut (Juglans regia L.) under different treatments and bench graft­ing conditions in cultivar Seinovo (control) and the selections 'Ovcar', 'G-286', 'Elit' and 'G-139'. Three treatments were applied: Treatment 1 - covering the graft with sawdust up to the top of the scion without dipping the scion and graft union in paraf­fin; Treatment 2 - covering the graft with sawdust up to the top of the scion and dip­ping the scion and graft union in paraffin; and Treatment 3 - covering the graft with both sawdust, up to the top of the scion, and polyethylene foil, and dipping the scion and graft union in paraffin. The best results of the parameters tested were obtained in the treatment involving dipping the graft in paraffin and covering it with both saw­dust, up to the scion, and polyethylene foil. The treatment without the use of paraffin, involving only the covering with conifer sawdust up to the top of the scion yielded the poorest results.
In 1999–2001 years on rootstocks of I, II, III quality of Rosa multiflora Thunb., thornless, the buds of two cultivars (Friesia and Nina Weibull) from the floribundas group were budded from different thickness scions. The dominant influence of quality of the rootstock on budding results of studied rose cultivars from the floribundas group was ascertained, however the quality of the scions didn’t matter. The planted rootstocks of I quality rooted very well every three vegetations seasons. In years 2000 and 2001, when the amount of rainfall during the first three months after planting was small, the rootstocks of II quality and particularly the ones of III quality, rooted in lower percentage than the rootstocks of I quality. During budding time the III quality rootstocks had thinner neck root in comparison to rootstocks I and II quality. Yet the rooted III quality rootstocks were budded in nearly 100%. The buds of roses of both cultivars on the III quality rootstocks overwintered in lower percentage than the ones budded on the I and II quality rootstocks. There was no significant influence ascertained in kind of quality of rootstock and of scion on number of I order shoots that grew in springtime from buds and on number broken off shrubs.
Two cultivars of Rosa thea hybrida were budded on the thornless Rosa multiflora Thunb. rootstock. The buds were cut down from scions in different ripeness phase of shoots (the flower buds closed; outside petals slightly opened; the opened flower; right after falling petals, two weeks after falling petals) and from different places on the shoot (upper, middle, lower part). Ripeness phase of shoots does not distinct influence on number of obtained shrubs and their quality. Good quality of shrubs were obtained when all buds from scions with outside petals slightly opened, with opened flower or right after petals fell were used. By budding the buds from upper part of the shoots the least number of shrubs was obtained, but with higher percentage of the first quality ones. Tested factors do not have any influence on the roots system.

Shrubs developed on buds from scions of different ripeness of shoots characterize similar vigorour of growth in respect of height, weight and number of basal shoots. Shrubs developed on buds from upper part of scions were higher, had bigger weight and number of basal shoots.
