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.

The effects of 19 rootstocks on growth, cropping and mean fruit mass of the 'Rubin' apple trees in fertile soil were investigated in the years 2001-2006. Six years after planting, the trunk cross-sectional area (TCSA) was the largest on P 62, M.9 EMLA and Arm 18, and the smallest on PJ 629 (No. 629), J-TE-G, PB-4, P 59 and No. 280. The highest cumulative yields per tree were obtained on the most vigor­ous rootstocks as well as on B 491, P 16, P 63 and P 65. Trees on the latter four root- stocks gave the highest yields per hectare. Trees on P 66 could also be very produc­tive if they were planted at the right density, adequate to their tree size. Trees on P 59, No. 280, P 22, PB-4 and J-TE-G showed a high yield efficiency (expressed as a ratio of cumulative yield to the final TCSA); however, due to the small tree size their yield per area unit was lower. Mean fruit mass for the 5 -year period was not significantly influenced by the rootstocks. The exception was PJ 629 which produced the smallest fruits.

Mycorrhizal fungi are gaining interest in the floriculture sector due to the beneficial effects on a crop performance and ornamental quality. The aim of the current study was to assess the effect of inoculation with the arbuscular mycorrhizal (AM) fungi Rhizophagus irregularis on ornamental quality of Begonia × semperflorens-cultorum grown in two different protected cultivation systems: a shadehouse or glasshouse. The inoculated plants incurred a significant increase of plant height by 34.6%, lateral shoot length by 27.9%, number of lateral shoots by 41.2%, number of flowers per plant by 102.9%, flower diameter by 27.5%, and stems dry weight by 263.6%. High temperatures in the glasshouse negatively affected the AM root colonization. On the contrary, shading induced higher mycorrhizal colonization (48.6%) and increased plant height, number of lateral shoots, number of flowers per plant and flower diameter compared to the glasshouse environment. Taking all together, our results clearly demonstrated that mycorrhizal inoculation at transplanting and shading may be beneficial to floriculture growers wishing to produce high quality B. semperflorens-cultorum plants during the spring-summer season.

The effect of the subclones of M.9 (M.9 T 337, Pajam 1, RN 29) and the sub­clones of P 22 (P 22/K, P 22/A, P 22/J), and some of the new Polish rootstocks (P 59, P 60, P 61 and P 62) on the growth and yield of 'Jonagold', 'Ligol' and 'Gala' apple trees was studied in a field experiment over a period of 10 years. The growth vigour of these cultivars on the M.9 subclones was similar to that observed on the standard rootstock M.9 EMLA and among the subclones of P 22, and was similar to those for the standard P 22. Trees of 'Jonagold' grafted on the new Polish rootstock P 62 were significantly less vigorous than those on M.9 EMLA. Trees grafted on P 61 were significantly smaller than the standard trees on P 22. The smallest trees of the tested cultivars were obtained on P 59. In the group of semi-dwarfing rootstocks, the small­est trees were on P 60 and the largest on P 14. The cumulative yields of tested culti­vars on the subclones of M.9 were similar to that on standard rootstocks of M.9 EMLA. The cumulative yields of tested cultivars on subclones of P 22 were similar to standard P 22. In the semi-dwarfing group, the highest yields for 'Jonagold' and 'Gala' trees were on P 60 and for 'Ligol' trees on P 14. The values of the yield effi­ciency index for the subclones of M.9 and new rootstock P 62 were similar to those for M.9 EMLA. Among the subclones of P 22 and new rootstock P 61, the values of this index were similar to those for the standard P 22 rootstocks. The highest yield efficiency index among the semi-dwarfing rootstocks was obtained for P 60. The tested subclones of M.9 and P 22 and new rootstocks P 61 and P 62 produced no significant effect on the size, weight and colouring of apples, with the exception of 'Jonagold' and 'Gala' trees growing on P 59. In 2004, the apples on this rootstock were significantly smaller.
