“…The pollination system of P. merkusii is cross-pollination. Wind and rain help its pollen distribution and seed dispersal, as well as, the formation of pollen stores throughout the year, especially from March-June (Pousujja et al, 1986;Babayan, 2022;Saimova et al, 2022). Although P. merkusii is known as a plant that typically grows on high plains, it also grows on lowlands and in harsh soil conditions.…”

Pinus merkusii is a potential wood that naturally grows in Central Sumatra (Kerinci) and North Sumatra (Aceh and Tapanuli), Indonesia. The Kerinci landrace has a different morphology from the other two Sumatran Pinus landraces, namely, Aceh and Tapanuli, but its placement is at the same taxonomic level. Hence, additional characters need evaluation to validate taxa on P. merkusii landrace belonging to Kerinci. This study aims to identify differences in genetic characters between Kerinci and Aceh (Rao and TAHURA [Taman Hutan Raya]) landraces using SRAP for long-term use and future conservation. DNA extraction ran from the leaves of 24 individual trees belonging to three populations of P. merkusii, i.e., one naturally occurring population in Kerinci and the two cultivated populaces found in Rao and TAHURA, Indonesia. Using seven SRAP combination primers, the analysis revealed an immense variety of alleles (bands). Overall, the amplification produced 62 bands, with nine, on average, per primary pair. However, most bands were polymorphic (91.79%), and only 0.57% were monomorphic. With 45% informative bands, the Kerinci landrace has the highest band variation. A combination of primer C (Me1 + Em3) at 900 bp and primer I (Me3 + Em1) at 1050 bp band size indicated specific bands that served as molecular characteristics. A crucial molecular characteristic distinguishes the landraces of P. merkusii found in Kerinci and other populations in Rao and TAHURA, Indonesia. The study revealed superior genetic variation among the P. merkusii populations evaluated.

“…Pinus is the largest genus in the Pinaceae family, with 111 species, mainly naturally distributed in temperate parts of the northern hemisphere [1,2]. A small number of species occurs in tropical and sub-tropical climate zones, including P. massoniana, native to Taiwan, a wide area of central and southern China and northern Vietnam [2,3], and P. merkusii, which has a disjunct distribution in Southeast Asia, including northern Sumatra and the Philippines [2,4,5]. Both species have been used for large-scale afforestation [3,4,6,7].…”

The total forest area of pine plantations in Vietnam is about 300,000 hectares, comprising, mainly, Pinus massoniana (160,000 ha) and P. merkusii (90,000 ha) [8][9][10].…”

Pine tussock moth (Dasychira axutha Collenette (Lymantriidae)) and masson pine caterpillar (Dendrolimus punctatus Walker (Lasiocampidae)) cause serious damage to Pinus massoniana and P. merkusii plantations in Vietnam. An integrated pest management (IPM) program is required to control these pests. Therefore, this study was undertaken to identify damage thresholds and to evaluate control options for implementing IPM in the Northeast and North Central regions of Vietnam. Three damage thresholds were considered: <25%, 25%–50% and >50% loss of leaf area. Control options were manual collection of eggs and pupae and the use of light traps and biological agents. An initial IPM model was developed for each pest and these gave control efficacies of 82.4% (Da. axutha on P. massoniana) and 77.8% (De. punctatus on P. merkusii). Six extended IPM models were undertaken by forest companies giving pest control efficacies of 79.2%–85.9%. The collection of pine resin provides an important source of income to local communities and the resin yield in the IPM models increased by 20.9%–22.7% compared to untreated control plots. The IPM protocols would help in developing policies that promote a more sustainable management of forest pests in Vietnam, thus reducing dependence on the use of insecticides of environmental and public health concerns.
