Molecular characterization Pinus merkusii native Kerinci revealed by rbcL

World Journal of Advanced Research and Reviews, 2022
Pinus merkusii native Kerinci, also known as Sigi, shares the same taxonomic family as Pinus merkusii native Aceh but differs in morphology, anatomy, and physiology. Additionally, P.merkusii Kerinci has a high utilization potential but its population is decreasing and the entry of P.merkusii native Aceh around the Kerinci population can result in the ...

The effect of stimulants and environmental factors on resin yield of Pinus merkusii tapping [PDF]

BioResources, 2020
Oleoresin from Pinus merkusii is one of the most important forest products in Indonesia. The objective of this study was to examine the effects of various stimulants and environmental factors on oleoresin yield. The first factor was the stimulant treatment, i.e., SAEt1 (20% sulfuric acid + 1% Ethephon); SAEt2 (20% sulfuric acid + 2% Ethephon); SR4 ...

Grass Communities Differ Floristically Under Different Dominant Trees in Savannas in Thailand and Cambodia

Biotropica, Volume 58, Issue 2, March 2026.
In total, we recorded 160 unique grass species across four savanna ecosystems dominated by different tree genera. These savannas support distinct grassy assemblages, but common grasses are often shared between ecosystems. ABSTRACT Southeast Asian savannas are some of the least studied ecosystems, with understanding of their function and resilience ...

THE INFECTION PROCESS OF Fusarium subglutinans IN Pinus merkusii SEEDLINGS

AGRIVITA Journal of Agricultural Science, 2014
Pinus merkusii or tusam is an original Indonesian plant and it is naturally distributed in Aceh and North Sumatra. Damping-off disease is the main problem in its nurseries. Fusarium subglutinans is one of the leading causes of damping-off disease. The knowledge of fungal infections process of tusam seedlings is essential to control damping- off disease
