Effect of cutting time and IBA application on rooting of edible cherry laurel (Prunus laurocerasus cv. 'Kiraz') cuttings

Abstract

Cherry laurel known as "karayemiş", "laz cherry" or "taflan", is a popular evergreen racemes fruit in Turkey and some other Caucasus countries. In this study, cherry laurel variety 'Kiraz' was propagated with hardwood, semi-hardwood and softwood cuttings with half leaf and effect of IBA application on rooting ability was determined. Cuttings with different lignification phase were collected from October, December, February (hardwood cuttings), May (softwood cuttings) and June (semi-hardwood cuttings) between 15th to 20th days and subjected to 0, 50, 100, 500 and 1000 ppm Indolebutryicacid (IBA). Cuttings were planted in bottom heated trays with perlite and over misting under greenhouse conditions. The percentages of rooting (100%), rootling (100%) and mortality (100%) were the highest at July's semi-hardwood cuttings while rooting degree was the highest at December hardwood cuttings (7.72). 100 ppm IBA concentration gave the highest ratios of rooting (96.44%), first grade rootling (90.22%) and mortality rate (84.89%). These results suggest that cherry laurel varieties could be easily propagated easily by July's semi hardwood cuttings subjected to 100 ppm IBA in perlite has bottom heating under greenhouse conditions with misting.Çelik alma zamanı ve IBA uygulamasının karayemiş (Prunus laurocerasus cv. 'Kiraz') çeliklerinin köklenmesi üzerine etkileri Anahtar Sözcükler: Cherry laurel Cutting time IBA Rooting ÖZET "Laz kirazı" veya "taflan" olarak da adlandırılan karayemiş, son yıllarda Türkiye ve bazı Kafkas ülkelerinde popüler olmaya başlayan herdemyeşil bir meyvedir. Bu çalışmada Prunus laurocerasus türüne ait Kiraz karayemiş çeşidinden farklı zamanlarda alınmış olan yeşil, yarı-odunsu ve odunsu yapraklı çeliklerin köklenmesi üzerine farklı dozlardaki IBA uygulamalarının etkisi araştırılmıştır. Ekim, Aralık, Şubat ve Temmuz aylarının ilk yarısında ve farklı odunlaşma aşamalarında alınan çelikler 5 farklı dozda (0, 50, 100, 500 ve 100 ppm) IBA uygulanmıştır. Çelikler sera şartlarında alttan ısıtmalı tavalardaki perlit içerisinde ve mistleme altında köklendirilmiştir. Temmuz ayında alınan yarı odunsu çelikler köklenme, fidan randımanı ve yaşama oranı bakımından %100'lük başarı göstermiştir. Köklenme derecesi ise Aralık ayında alınan çeliklerde 7.72 ile en yüksek olmuştur. 100 ppm IBA dozu gerek köklenme (%96.44), gerek fidan randımanı (%90.22) gerekse yaşama oranı bakımından en yüksek değerleri vermiştir. Bu çalışmanın sonuçlarına göre karayemişler, Temmuz ayında alınan yapraklı yarı odunsu çeliklere 100 ppm gibi düşük IBA dozu uygulanarak seradaki perlit ortamında ve mistleme altında kolaylıkla çoğaltılabilir.

Effect of Cutting Time and IBA Application on the Rooting of Goji Berry Cuttings

“…On the other hand, the cuttings that were taken from Damaye goji berry variety in October and the control group cuttings that did not apply IBA and the cuttings that were taken in December with the dose of 0 (control) or 2000 ppm IBA and the cuttings that were taken from the NQ7 variety in December and applied 1000 or 2000 ppm IBA dose could not be rooting obtained (Table 1). These findings are the same with Celik et al (2015) results. Again, only 2.67% of the cuttings taken from Damaye variety in December could be transplanted and this value was recorded as the lowest level (Table 2).…”

“…It is stated that fully green cuttings are not preferred for goji berries, which can be reproduced with semi hard-wood and/or hard-wood cuttings taken in summer or winter time. In addition, it has been determined that the application of auxin group growth regulators that increase rooting in cuttings also increases the rooting success (Feng et al, 2000, Celik et al, 2015Asanica et al, 2016). In the present study, which investigated the effects of cutting taking time and IBA application on rooting in the reproduction of goji berries, 4 different doses of IBA (0, 500, 1000 and 2000 ppm), planted in perlite medium in bottom heated trays and they rooted under high tunnel conditions with misting.…”

“…Considering only the cutting time, it was determined that the highest rooting rate was obtained from the cuttings taken in August with 52.83%, and when the rooting rate was evaluated only in terms of variety, Damaye variety had a higher rooting rate with 23.17% (Figures 3 and 4). According to Celik et al (2015) semi hardwood cuttings taken in the end of the growing period, roots better than fully dormant cuttings. On the other hand, the cuttings that were taken from Damaye goji berry variety in October and the control group cuttings that did not apply IBA and the cuttings that were taken in December with the dose of 0 (control) or 2000 ppm IBA and the cuttings that were taken from the NQ7 variety in December and applied 1000 or 2000 ppm IBA dose could not be rooting obtained (Table 1).…”

Effects of Externally Applied IBA Doses on Rooting and Sapling Characteristics of Autumn Olive Berry Cuttings Taken at Different Periods

“…Similar results were also revealed in the oleander plant by Şeker et al [31] in arbutus, Pivetta et al [32]. Çelik et al [19] in cherry laurels, Çelik [16] in blueberries and Kim et al [30] in acacia can also state that rooting change according to the cutting taking time. It is also stated that the Autumn olive berry can easily be rooted under semi-woody cuttings under mist watering, but it is mandatory to apply 8,000 ppm IBA in powder form [24].…”

“…And root number decided whether the cuttings should be removed from the rooting medium according to the rooting condition. Rooting degree as expressed 1-9 scale calculated by the root formation of the cuttings as, 1-no root, 3-weak roots, 5-medium roots, 7-strong roots and 9-very strong root formation put forward by analogy with the report of Çelik [16] and Çelik et al [19]. ArcSin √x transformation was applied to the percentage values, while statistical analyzes were performed with the SPSS-23 statis-tical program, and the real difference between the cutting taking time, IBA doses and their interactions was evaluated by Duncan Multiple Range Test.…”
