To determine the most proper bed, time, and wounding factors on the rooting of semi-hard cuttings of olive (Olea europaea), cuttings were selected and research was conducted at the Faculty of Agriculture of the Tehran Univ. in Karaj. The required cuttings were taken from healthy and similar mother trees at the Roodbar Research Station. Then, semi-hard cuttings of 15 cm in length and 3 to 5 mm in diameter with four terminal leaves were prepared. Then those prepared cuttings were treated with IBA at 4000 ppm and Captan fungicide at 3000 ppm before planting. This experiment was designed in a factorial with a randomized complete block, with four media bed factors for rooting in seven levels (peatmoss + perlite, sawdust + sand, peatmoss + sand, and perlite, sand, and perlite + sand), the time factor for cutting preparation in four levels (May, August, September, and March), cultivars at two levels (Roghani and Zard Zeitoun), and wounding treatment at two levels (unwounded and wounded); there were three replications (20 cuttings per replicate per each unit). The results indicate that, among the selected beds, perlite with 53% of rooting average yield has the highest and peatmoss + perlite with a rooting average of 43.8% has the lowest. As far as time is concerned, those cuttings prepared in March show the highest rooting average of 69.3%, while those prepared in August show the lowest average of 12.7%. The comparison between the two cultivars shows that Roghani, with 60.4% rooting yield, is preferred to Zard Zeitoun, with 48.2% rooting average. There were no significant differences between wounded and unwounded cuttings with regard to rooting.

Technical grade prohexadione-calcium (93.2% a.i. P-Ca) applied to `Fuji'/M.9 trees in three applications in deionized water reduced shoot growth by 25%, but the addition of (NH4)2SO4 to P-Ca suppressed shoot growth by 47%. If P-Ca was mixed in well water (high in calcium salts), P-Ca did not suppress shoot growth at all. The commercially formulated prohexadione-calcium [Apogee: 27.5% P-Ca + 56.1% (NH4)2SO4 + 16.4% other proprietary additives] + Regulaid in well water (high calcium) was not as effective (reduced growth by 30%) as when additional (NH4)2SO4 was added (reduced growth by 53%), and if CaCl2 (used to control corking) was tank mixed with Apogee + Regulaid, the Ca++ interfered with the growth suppression of P-Ca. If (NH4)2SO4 was added at the same rate as CaCl2 (w/w), the Apogee growth suppression was completely restored (reduced growth by 50%). Choice (a commercial water conditioner that has (NH4)2SO4 in the formulation, among other ingredients) + Li-700, or (NH4)2SO4 + Silwet L-77, or (NH4)2SO4 + Silwet L-77 + Oil were among the most effective adjuvant combinations with Apogee. The addition of ethephon at 270 mg·L-1 improved the growth suppression of Apogee + (NH4)2SO4 + Regulaid. Solubor compromised the effectiveness of Apogee + Regulaid. Adjusting the pH of the Apogee + (NH4)2SO4+ Regulaid spray to either pH = 4 or pH = 9 did not affect efficacy. The combination of Apogee + (NH4)2SO4 + Regulaid caused increased fruit cracking of `Empire' fruit as compared to the control (7%), presumably due to increased absorption of P-Ca. Chemical names used: Prohexadione-calcium (P-Ca, 3-oxido-4-propionyl-5-oxo-3cyclohexenecarboxylate) formulated as BAS-125 (10% P-Ca); Apogee (27.5% P-Ca), or Technical 93.5% P-Ca); Regulaid (polyoxyethylenepolypropoxy-propanol, alkyl 2-ethoxethanol, and dihydroxy propane); Silwet L-77 (polyalkyleneoxide modified heptametyltrisiloxane, silicon surfactant), LI-700 (80%, phosphatidylcholine, methylacetic acid and alkyl polyoxyethylene ether); Superior Oil (Drexel Damoil 70-second delayed dormant spray oil); ethephon (2-chloroethyl phosphonic acid); Solubor (20.5%, Boron equivalent); captan (N-Trichloromethylthio-4-cyclohenene-1,2-dicarboximide).
