“…When using semi-hardwood cuttings, IBA is the most commonly used auxin as it frequently promotes rooting more efficiently than NAA (Das et al, 2006;İsfendiyaroğlu and Özeker, 2008), with a few exceptions (Serrano et al, 2002). In other cases, however, the combination of both auxins results in better rooting rates, but genotype seems to play a major role (Denaxa et al, 2010;Khabou, 2002). IBA also produces better results than NAA in microcuttings (Bati et al, 1999).…”

Olive (Olea europaea) is one of the most important fruit species in the Mediterranean basin, where 95% of the world's olive orchards are planted, and it has become an economically valuable crop worldwide, due to an increasing interest in olive oil for human consumption. New olive orchards are being planted outside the Mediterranean, calling for an effort to identify the genotypes best adapted to the new conditions. However, some olive cultivars remain difficult to propagate, which significantly reduces the capacity to use the full genetic diversity of the species. Improving rooting ability in cuttings from recalcitrant olive cultivars has become a critical topic, which implies fundamental research on the anatomy, physiology, biochemistry and genetics of the adventitious root formation process. Besides, the existence of different rooting behaviors among olive cultivars also makes the species a candidate model plant for these studies. Olive propagation techniques evolved through time from field-or nursery-planted hardwood cuttings, to semi-hardwood cuttings in greenhouses under mist, and, more recently, to in vitro culture techniques. Nevertheless, research about adventitious root formation carried on each propagation method was mostly based on trial and error approaches. Researchers have mainly investigated different factors involved in the process of adventitious rooting by testing their effect in the rooting capacity of different cultivars, leading to a high dispersion and fragmentation of the available information. The goal of this review is to present the most relevant results achieved on adventitious root formation in olive cuttings, aiming to provide an integrated perspective of the current knowledge.

“…Namun demikian, beberapa tanaman anggota Myrtaceae seperti Syzygium javanica dan jambu biji (Psidium guajava L.) telah dilaporkan sebagai tanaman yang sulit berakar dengan persentase berakar hanya 20-30% ketika dicangkok atau disetek tanpa menggunakan zat perangsang akar (Paul dan Aditi, 2009;Sardoei, 2014;Yusnita, et al, 2018). Keberhasilan pengakaran pada cangkok atau setek dipengaruhi oleh banyak faktor yang mungkin saling berinteraksi satu sama lain, di antaranya ialah faktor genotipe (Zaczek et al, 2006;Denaxa et al, 2011), umur fisiologi bahan tanaman (Santoso, 2014), umur ontogenetik tanaman (Zaczek et al, 2006), musim, temperatur, fotoperiodisitas (Singh et al, 2011), media pengakaran yang digunakan (Shadparvar et al, 2011;Ansari, 2013;Benti, 2014;Rahmania dan Kurniawati, 2014), ukuran bahan perbanyakan (Rahmania dan Kurniawati, 2014;Apriani dan Suhartanto, 2015), dan zat pengatur tumbuh (ZPT). Zat Pengatur Tumbuh, terutama dari golongan auksin merupakan salah satu faktor penentu dalam keberhasilan pengakaran pada cangkok berbagai tanaman yang sulit berakar (Dirr dan Junior, 2006;Hartmann et al, 2011).…”

A study to determine the effect of auxin talcum on rooting of air layered malay apple (Syzygium malaccense (L.) Merr. & Perry) was conducted from March to May 2016. The experiment was arranged in a randomized complete block design with three replications, five branches per experimental unit. Auxin talcum treatment consisting of 7 level of auxin concentrations, i.e., (in ppm) 0 (control), 2000 IBA, 4000 IBA, 2000 NAA, 4000 NAA, 1000 NAA + IBA 1000 and 2000 IBA + 2000 NAA in the form of talcum-paste were applied in the upper region of the girdled branches prior to being covered with soil medium. The results showed that after two months, all treatments containing NAA, either singly or in combination with IBA produced 100% rooting, whereas the control treatment was only 22%. The IBA treatments singly at 2000 and 4000 ppm produced 44.4% and 55.6% rooting, respectively. The superiority of NAA upon IBA treatments was also shown by the higher number and length of primary roots as well as earlier root formation. The best treatment for Malay apple rooting was 4000 ppm NAA which produced 33.3 roots, and formed roots three weeks earlier than the control treatment.Key words: air layering, auxin, IBA, NAA, rootingABSTRAKPenelitian ini bertujuan mempelajari pengaruh formulasi pasta auksin yang mengandung IBA, NAA atau kombinasi keduanya terhadap pengakaran cangkok jambu bol (Syzygium malaccense L.) Merr. & Perry). Percobaan dilaksanakan dari bulan Maret sampai Mei 2016 menggunakan rancangan acak kelompok dengan tiga ulangan, 5 cabang cangkokan per unit percobaan. Perlakuan terdiri atas 7 taraf konsentrasi auksin (dalam ppm) yaitu 0 (kontrol), 2000 IBA, 4000 IBA, 2000 NAA, 4000 NAA, 1000 NAA + IBA 1000 dan 2000 IBA + 2000 NAA. Hasil pengamatan pada dua bulan setelah perlakuan, semua perlakuan yang mengandung NAA, baik secara tunggal maupun dalam kombinasi dengan IBA menghasilkan 100% cangkok berakar, sementara kontrol hanya menghasilkan 22%, dan perlakuan IBA saja pada 2000 dan 4000 ppm menghasilkan 44.4% and 55.6% cangkok berakar. Efektivitas NAA yang lebih tinggi dibandingkan IBA juga ditunjukkan oleh lebih tingginya jumlah akar, panjang akar dan waktu terbentuknya akar yang lebih awal dibandingkan kontrol. Perlakuan auksin terbaik didapatkan pada 4000 ppm NAA yang menghasilkan 33.3 akar primer dan mempercepat terbentuknya akar hingga tiga minggu lebih awal dibandingkan dengan pada cangkok tanpa auksin.Kata kunci: auksin, cangkok, IBA, NAA, pengakaran

“…Unfortunately, leafy cuttings of Kalamata present a very low rooting ability (0−5%) and thus it is characterized as a hard-to-root cv [3]. Earlier studies have shown that the exogenous applied auxins failed to promote rooting in Kalamata cuttings, or they had only a slight rooting effect [3,10].…”

Shoot Girdling Improves Rooting Performance of Kalamata Olive Cuttings by Upregulating Carbohydrates, Polyamines and Phenolic Compounds

2021

Girdling (a ring of bark approximately 5 mm wide) was applied on olive mother plants to investigate its effect on the rooting ability of cuttings. Treatment was applied in autumn and in spring. The cuttings were then immersed for 5 s into 2000 mg L−1 indole-3-butyric acid (IBA) in a 45% v/v ethanolic solution. Thirty days after girdling, cuttings were taken from girdled and control shoots from the part just above the girdle zone (basal), as well as from the part right above (middle). The base of the cuttings was collected, and the concentration of polyamines, phenolic compounds and soluble carbohydrates was determined. Girdling enhanced the rooting performance of the cuttings, while autumn proved to be a better season for rooting compared to spring. Girdling positively affected the concentration of all the measured parameters. The main characteristics of autumn cuttings were the high levels of glucose, mannitol, free and total polyamines, hydroxytyrosol, tyrosol, verbascoside, oleuropein, quercetin and luteolin. The cuttings taken from the middle part of the girdled shoot exhibited high sucrose, glucose, mannitol, free polyamines, hydroxytyrosol, luteolin-7-glucoside, total phenols and flavanol concentrations. Nonetheless, further research is needed in order to draw conclusions on the overall efficiency of girdling on inducing rooting of olive cuttings.
