“…Previously, P. colubrinum , a Phytophthora ‐resistant species originating from Brazil, had been used as rootstock for grafting P. nigrum to create P. capsici ‐resistant black pepper (Albuquerque, 1969) although grafts appeared to deteriorate after 4 years (Alconero et al, 1972). Furthermore, grafts suffered from lower productivity and low drought tolerance (Nguyen et al, 2019). More recently, P. flaviflorum has been tested as a rootstock to create oomycete‐resistant black pepper grafts (Fan et al, 2022).…”

Black pepper (Piper nigrum) is a spice commonly used in kitchens throughout the world. Black pepper production is devastated by a range of pathogenic agents, including Phytophthora capsici and Meloidogyne incognita. Many efforts have been directed towards finding black pepper cultivars that are resistant to these pathogens. In this work, a 39‐accession germplasm panel of species in the Piper family collected throughout Vietnam was described. Preliminary tests using P. capsici inoculation onto leaves were carried out to identify potentially resistant accessions. Next, candidate plants were inoculated with P. capsici mycelial suspension and survival rates were assessed 15, 30 and 45 days postinoculation. In addition, Piper plants were challenged with M. incognita by adding larvae/juveniles to growing pots. Resistance to M. incognita was determined by the number of root galls and the percentage of plants with yellow leaves 1, 2 and 4 months after treatment. Piper accessions were also subjected to a 4‐day waterlogged treatment. Two accessions (HUIB_PH30 and HUIB_PD36) demonstrated high levels of resistance to all biological and water stresses. Micromorphological characterizations revealed that the amount of intercellular spaces in the root cortex correlated with the resistance to P. capsici and waterlogging tolerance. Hence, the abundance of intercellular spaces can serve as a guide for further selection of black pepper accessions that are resistant to common diseases and tolerant to waterlogged conditions.

“…Pada batang ortotrop melada terdapat 11-14 berkas angkut modular dan 42-46 berkas angkut periferal, sedangkan pada lada hanya terdapat 9 berkas angkut modular dan 34-38 berkas angkut periferal (Ravindran and Remashree 1998). Ketika berhasil berbuah, produktivitas lada sambung dilaporkan lebih rendah dan lebih rentan terhadap kekeringan daripada lada non-sambung (An et al 2019). Oleh karena itu perlu diteliti sifat pertumbuhan lada sambung dalam upaya inovasi perbaikan agroteknologi budidaya lada sambung sebagimana disarankan oleh (Evizal and Prasmatiwi 2019).…”

Wild pepper of Piper colubrinum Link is used as rootstocks for grafted black pepper (Piper nigrum/Piper colubrinum) because its resistance to fungi that cause root rot disease. Grafted black pepper nurseries and plantations began to be developed by farmers in Lampung. This research aims to study the growth characteristics of wild pepper and grafted black pepper plants. The research was conducted in the field of wild pepper and grafted black pepper owned by farmers in Air Kubang Village, Air Naningan District, Tanggamus, Lampung, using survey method. Plant samples were determined randomly in the fields. The results showed that: (1) Wild pepper plants starts at the age of 1 year form plagiotropic branches with small diameters every 1-2 orthotropic branches, but slowly form orthotropic branches; (2) After the second pruning (of harvesting cuttings) 22% of the plants form orthotropic branches. The yield of pepper cuttings from the first to third harvests increased by 21-25% compared to the previous yield. In the third harvest, the production of cuttings reached 5066 cuttings (2 nodes) per 400 m2 land area or equivalent to 126,650 cuttings per ha of land harvested every 2 months; (3) At the age of 18 months, compared to non-grafted, grafted black pepper showed a greater greeness leaf index, larger stem diameter, larger plagiotropic branch diameter, higher number of orthotropic and plagiotropic branches, and 15.6% of grafted black pepper plants were flowering. Key words : Black pepper, cutting, flowering, growth, grafting, Piper colubrinum
