“…After 30 days, cutting were planted in plastic boxes filled with a mixture of sand: peatmoss: vermiculite (1:1:1 v/v) treated with fungicide (benlate) (1g/ kg mixture). All pots were placed in a greenhouse and irrigated with water with same pH (5 or 7), to reach 20 % moisture (Tsipouridis and Thomidis, 2004). The pH of irrigation water was adjusted by HCl and NaOH.…”

T HIS experiment was conducted on 2019 & 2020 to study the effect of root hormones within two different water irrigation pH. on five new almond ×peach hybrids that are nematode resistance and salt tolerance. Rootstock trees are nine years old grown in Horticulture Research Institute, A.R.C. and received the same recommended horticultural practices. This experiment consisted of eight treatments using Indole Butyric Acid (IBA) at concentrations of 1000&2000ppm with or without 500ppm Naphthalene Acetic Acid (NAA) under pH5&7 of water irrigation. Results cleared that hybrid genotype No.5 recorded the highest significant values in growth and chemical measurements followed by hybrid genotype No.4 while Hybrid genotype No.3 recorded the lowest significant values. The greatest rooting percentage (56.28&59.76) and root length (4.01&4.23 cm.) recorded with 1000ppmIBA+ 500ppmNAA, as auxins enhanced the formation of callus, promotes root primordia. IBA delays the leaf abscission that increase the partitioning of photo-assimilates towards the leaves to reach great leaf area (32.98&34.34), fresh (2.11& 2.53) and dry (0.89&0.97) weight. Great leaf area and introduce more C/N ratio. Irrigation by pH5 improves nutrient availability and solubility of soil anions than pH7 of irrigation water. The interaction between hybrid No.5 under 1000ppmIBA+500ppmNAA within pH5 of water irrigation recorded the highest significant values of all growth measurements (rooting % 67.2&58.8, root number 5.95&6.03, shoot length 7.30&7.51cm. and leaf area 8.3&38.9 cm 2 .) and chemical measurements fresh (2.59&2.71), dry (1.12&1.28) weight and total indoles (0.471&0.483). Moreover normal water pH reached the good rooting measurements with the high concentration of IBA (2000 ppm).

“…Therefore, longer adventitious roots generated by soaking in the OW can positively affect nutrients uptake and plant growth, increasing quality and yield. Early development of adventitious roots of chrysanthemum cuttings soaked in OW may be explained by active oxygen species including H 2 O 2 from ozone self-decomposition, in the absence of auxin, as many researchers reported (Gaspar et al, , 2002Shelp et al, 1995;Tsipouridis et al, 2004). Optimal combinations of DOC of OW and soaking duration promote early root development of chrysanthemum cuttings.…”

To examine the effect of soaking in ozonated water (OW) on development of adventitious roots, basal ends of chrysanthemum cuttings (Chrysanthemum morifolium Ramat.) were soaked in 1, 3 or 5 mg L À1 OW, in an indol-3-butyric acid (IBA) solution prepared from a commercial root promoting agent or in distilled water (DW). At 20 day after transplanting (DAT), a significant increase in adventitious root number (ARN) was observed in the IBA-treated cuttings but early root elongation was delayed. When soaked in the 5 mg L À1 OW, ARN and total root length (TRL) grown over 40 mm were increased with a decrease in soaking duration (from 50 to 5 min). Lateral root number (LRN) of the cuttings soaked in the 3 mg L À1 OW for 1 h showed four times higher than that of the DW treatment at 19 DAT. Optimal combination of dissolved ozone concentration and soaking duration can promote early root elongation and LRN of chrysanthemum cuttings. From a comprehensive standpoint, a high DOC of OW with a short soaking duration (3 mg L À1 · 1 h and 5 mg L À1 · 5 min) worked as well as IBA for adventitious rooting of chrysanthemum cuttings. These findings indicate that ozonated water can be an alternative to root promotion agents for adventitious rooting of chrysanthemum cuttings.

“…Preparation of rooting substrate: Rooting substrate was prepared from perlite (Tsipouridis et al, 2005), 7.5 L perlite was put in polyethylene bags and 1.5 L of H 2 O 2 3 % (in tap water) was added instead of water with different pH (5, 7 and 9), to reach 20 % moisture (Tsipouridis and Thomidis, 2004). The pH was adjusted by HCl and NaOH.…”
