“…Furthermore, the progeny GEN28 showed ability of root development under a scenario of nematode infestation (Pasqualotto et al, 2020). It is noteworthy that the use of rootstock can accelerate the availability of technology for coffee management in infested areas, thus minimizing production losses (López-García & Cruz-Castillo, 2019;Myers et al, 2020). However, most studies have used C. canephora rootstock (Bertrand et al, 2000;Gonçalves et al, 2021), and in this study C. arabica was used.…”

Meloidogyne paranaensis is a species of root‐knot nematode that affects coffee (Coffea arabica L.) tree growth by causing severe damages to the plant root. This study evaluated the agronomic performance of Coffea arabica progenies in an M. paranaensis‐infested field and assessed the compatibility of resistant C. arabica genotype 28‐I‐4 (GEN28) as rootstock for susceptible cultivars. Experiment 1: under field conditions, six progenies were analyzed; the controls were ‘IPR100’ as resistant and ‘Catuaí Vermelho IAC 144’ (CtV144) as susceptible. Experiment 2: under greenhouse conditions, combinations of grafts and rootstocks between susceptible CtV144 and GEN28 were evaluated regarding their resistance to M. paranaensis alongside their noninoculated counterparts. For this, M. paranaensis reproduction factor (RF), total population of the nematode per gram of root system, growth parameters, gas exchange, and water potential (ψpd) were evaluated. In Experiment 1, resistant C. arabica progenies were more vigorous, productive, and showed a population of M. paranaensis threefold‐times lower than that observed in roots of susceptible CtV144. Among the resistant progenies selected in the field experiment, GEN28 was chosen for physiological compatibility study with the traditional cultivar CtV144. In Experiment 2, the CtV144 grafted onto GEN28 led to resistance to M. paranaensis, as well as a higher leaf area and ψpd as compared with nongrafted CtV144. Therefore, the GEN28 holds suitable characteristics to be used as a new Coffea arabica rootstock applied to production of resistant seedlings to Meloidogyne paranaensis nematodes. This technology represents an alternative to keep up coffee activity in infested areas.

“…Kopi Liberika sering digunakan sebagai batang bawah di perkebunan kopi Robusta di Lampung Barat, Lampung Utara, Way Kanan, dan Tanggamus (Evizal, Sugiatno, and Prasmatiwi 2015). Sebagai batang bawah, kopi Liberika memiliki keunggulan toleran terhadap nematoda puru akar dan toleran terhadap lahan marginal untuk replanting (Myers et al 2020;. Pham et al (2020) melaporkan bahwa kombinasi grafting Robusta/Liberika dengan pemberian mikoriza efektif mengendalikan nematoda pada lahan kopi replanting.…”

Grafting of different coffee species (interspecific grafting) aims to take advantage of the superiority of the rootstock and promote the growth and production of the scion. For example, Robusta coffee is grafted with Liberika coffee as rootstock. One of the principles of fertilization is the application of fertilizer at the right time. This study aimed to determine the effect of clones of Robusta/Liberica interspecific grafting and different fertilization times on the growth and yield of Robusta coffee. The research was conducted in a 15-year-old coffee plantation with the rootstock of Liberika coffee of the Red Robinson variety which was grafted to the scion of multiclonal Robusta coffee. Planting distance of coffee was 2.5 m x 2.5 m and shade trees were Gliricidia sepium. This research used a split plot design arranged in a factorial (4x2) with three replications so that there were 24 experimental units. The main plot was the time of fertilization, namely in early April and October and in early May and November. As sub-plots, there were Robusta coffee clones, namely Korolla 1, Korolla 2, Tugu Bungkuk, and Darmani. The results showed that fertilization time, clones, and their interactions did not affect the number of primary branches, primary branch length, number of secondary branches, fruit weight of harvested samples, number of fruit per bunch, fruit weight per bunch, dry seed weight per bunch, and coffee yield per tree. The interaction of coffee clones and fertilization time had a significant effect on the number of pods per branch, the number of harvested samples, dry bean weight of harvested samples, dry bean weight per branch, and coffee yield per hectare. For Darmani coffee clones, delaying fertilization from April and October to May and November reduced coffee yield. Key words : Interspesific grafting, Liberica, Robusta, time of fertilization, yield

“…Penyambungan menggunakan batang bawah kopi Liberika yang tahan nematoda menekan serangan nematoda, meningkatkan pertumbuhan dan produksi serta mengurangi mortalitas pohon (Myers et al, 2020) dan cocok untuk untuk diterapkan pada penanaman ulang kopi pada lahan terinfeksi nematoda (Pham et al, 2020). Peningkatan fotosintesis kopi sambungan akan mendorong peningkatan pertumbuhan dan produksi kopi sambungan (Novaes et al, 2011).…”

Penyambungan (grafting) merupakan salah satu upaya untuk memperbaiki sifat tanaman menggunakan bahan klonal baik pada fase pembibitan, pemeliharaan maupun rehabilitasi. Keragaan sifat kopi Robusta dapat diperbaiki melalui penyambungan intraspesifik (Robusta/Robusta) untuk menghasilkan produktivitas yang lebih tinggi atau melalui penyambungan interspesifik (Arabika/Robusta) untuk menghasilkan kopi Arabika. Tujuan penelitian ini adalah untuk (1) mengetahui pertumbuhan dan produksi kopi grafting dibandingkan dengan kopi non-grafting dan (2) mengetahui pertumbuhan dan produksi kopi grafting Arabika interspesifik dibandingkan dengan Arabika non-grafting. Penelitian ini dilaksanakan di Desa Harapan Jaya, Kecamatan Way Ratai, Kabupaten Pesawaran, Lampung. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan perlakuan enam sistem penyambungan dengan empat ulangan. Perlakuan pada penelitian ini yaitu: P1=Robusta non-grafting, P2= Arabika non-grafting, P3= grafting Robusta/Robusta metode tak-ent, P4= grafting Arabika/Robusta + cabang, P5= grafting Arabika orthrotrop/Robusta, P6= grafting Arabika plagiotrop/Robusta. Penelitian ini menggunakan jenis kopi Robusta klon lokal Mekarsari, sedangkan untuk jenis kopi Arabika menggunakan varietas Kartika. Data dianalisis menggunakan uji lanjut yaitu Uji Beda Nyata Terkecil (BNT). Hasil penelitian menunjukkan bahwa masing masing perlakuan berpengaruh nyata terhadap variabel jumlah cabang primer, jumlah cabang plagiotrop (B0, B1, dan B2), jumlah dompol bunga per cabang, jumlah dompol putik per cabang, jumlah dompol buah hijau per cabang, jumlah dompol buah merah per cabang, bobot buah segar per cabang, bobot biji kering per cabang, jumlah biji panen per cabang, dan produksi per pohon. Berdasarkan hasil penelitian ini disimpulkan bahwa: (1) pertumbuhan dan produksi tanaman kopi grafting lebih tinggi daripada tanaman non-grafting, (2) dari berbagai sistem penyambungan kopi Arabika grafting interspesifik, perlakuan Arabika plagiotrop/Robusta menghasilkan pertumbuhan yang sama tetapi memberikan produksi biji lebih tinggi dibandingkan dengan perlakuan Arabika lainnya.
