Rooting of "Ayvalik" olive cuttings in different media

Abstract

The "Ayvalik" olive cultivar, the most grown for high quality olive oil in Turkey, is generally regarded as showing very good rooting ability. However, cuttings sometimes show moderate or even poor rooting performances, a problem likely related to the use of inappropriate rooting media. The aim of this work was to determine the most successful media among those traditionally used and to identify promising alternatives. October cuttings were planted in 25 different media in two consecutive years under mist propagation conditions. Substrates such as peat, perlite, bark, pumice, sand, polystyrene beads, phenolic foam, rockwool and vermiculite were used pure or in mixtures. In the first year the highest rooting percentage (100%) and visual rating scores (5) were obtained with phenolformaldehyde foam. Perlite-vermiculite (1:1 v/v) was associated with a 95% rooting percentage in both years. The highest mean number of roots (10.8), root length (47 mm), root dry (382 mg) and fresh weights (48.3 mg), and number of secondary roots (13) were recorded in the same medium in the second year. Rockwool, peat-polystyrene (2:1 v/v) and sand-perlite (1:2 v/v) also led to more than 90% of cuttings taking root, while pure sand, peat and peat-sand mixtures gave very low (5-28%) rooting percentages. Perlite-vermiculite 1:1 (v/v) and pre-sized rockwool cubes may be appropriate alternatives to traditional sand-perlite mixtures for rooting "Ayvalik" olive cuttings.

Effect of different growing media on the rooting of pomegranate (Punica granatum L.) cv. 'Phulearakta' cuttings

“…The means of root dry weight per plant showed that maximum dry root weight (0.61 g) was obtained in perlite + vermiculite followed by 0.60 g in vermiculite + cocopeat while the minimum dry root weight (0.47 g) was observed in control. These results are in accordance with the findings of Isfendiyaroglu et al (2009) who recorded that sand-perlite (1:2) gave the highest fresh weights and dry root weights in olive cuttings which probably due to good water holding capacity and porosity of Means with at least one letter common are not statistically significant (p <0.05) using LSD Test perlite. Khayyat et al (2007) recorded that improved fresh and dry root weights were in pothos by using cocopeat substrate.…”

“…Ansari (2013) reported that vermiculite mixed with sand was the best for higher per cent rooting and root numbers in pomegranate due to more water holding capacity and release of nutrients gradually from vermiculite medium. Isfendiyaroglu et al (2009) recorded that perlite-vermiculite medium induced very high rooting whereas root production is negatively affected when cuttings of olive grown in sand. Sutter (2005) also found that perlite-vermiculite (2:1 or 3:1 ratio) is the most commonly used propagation medium in Californian olive nurseries.…”

“…According to Walston (1996), the medium must be sterile to ensure that rooting is not harmful by the pathogens. The appropriateness of the medium depends on the species, type of cutting, season, propagation system used as well as cost and availability of the medium ingredients (Macdonald, 1986;Hartmann et al, 2002;Isfendiyaroglu et al, 2009). El-Naggar and El-Nasharty (2009) reported that potting media as well as nutritional requirements are the most important factors affecting the rooting and growth of plants.…”

Desempenho de substratos na capacidade de enraizamento de estacas de oliveiras

“…The use of sand as a substrate for growing fruit bearing species has shown positive results because, in addition to having very low ion exchange capacity, it is considered to be an easily managed substrate (ISFENDIYAROGLU et al 2009). The greatest limitation for use of sand as a substrate is the difficulty of handling due to excessive weight, especially when wet (OLIVEIRA et al 2012).…”

Compost as Peat Substitute in Olive Cutting Media

“…Whereas, better results were achieved when media with good aeration and a reduced water retention capacity were used for instance; root regeneration was strongly suppressed in pure peat, but the values for all rooting variables were significantly increased by mixing this with polystyrene and vermiculite in both years. The negative effects of peat are likely related to its high water retaining capacity (Isfendiyaroglu et al, 2009). In addition, organic by-products and composts tend to have porosity and aeration properties comparable to those bark and peat and as such are ideal substitutes in propagating media (Chong, 2005).…”
