dc.description.abstract | Teak (Tectona grandis) ist eine
hochwertige tropische Baumart und natürlich in Indien, Laos,
Myanmar und Thailand verbreitet. Mithilfe von 10 polymorphen
nukleären Mikrosatelliten- (SSRs) and 71 AFLP-Markern (Amplified
Fragment Length Polymorphisms) wurde die genetische Variation in
natürlichen Teakpopulationen in Myanmar untersucht. In
bewirtschafteten und unbewirtschafteten Populationen in jeweils
vier Regionen im Norden und Süden Myanmars wurden adulte Bäume und
ihre Verjüngung sowie in zwei Plantagen in Benin adulte Bäume
beprobt. Insgesamt wurden 1667 Proben mit SSRs und 1573 Proben mit
AFLPs untersucht.
Die genetische Diversität in den Teakpopulationen ist generell hoch
und es gibt keine signifikanten Unterschiede zwischen den
Bewirtschaftungsformen sowie zwischen den Adulten und der
Verjüngung. Die Populationen Myanmars weisen mit den SSR-Markern
eine niedrigere Diversität auf als die Populationen in Benin und

dc.description.abstracteng | Teak (Tectona grandis) is a valuable
tropical forest tree species which naturally occurs in India, Laos,
Myanmar and Thailand. Ten polymorphic nuclear microsatellite
markers (SSRs) and seventy-one AFLP markers (Amplified Fragment
Length Polymorphisms) were used to investigate genetic variation of
teak in natural populations in Myanmar for conservation and
sustainable utilization of genetic resources. Adult trees and young
regeneration were sampled in selectively logged and unlogged
populations in four regions, each in the Northern and Southern
parts of Myanmar, and two plantations in Benin. A total of 1667
samples and 1573 samples were used for SSRs and AFLPs,
respectively.
In general, genetic diversity within teak populations was
relatively high but not significantly different between management
types and between regeneration and adults. Myanmar populations were
less diverse than Benin populations with SSR markers and the
allelic richness was significantly higher in Southern than in
Northern populations of Myanmar. Additionally, inbreeding was
significantly higher in the regeneration in unlogged than in
selectively-logged populations. AFLP markers showed contrasting
patterns as the Myanmar populations were diverse than those of
Benin, and genetic diversity in Northern populations was
significantly higher than in the South of Myanmar. Furthermore,
genetic diversity of adult trees was significantly higher than in
the teak regeneration in unlogged populations.
For both markers, cluster and structure analyses revealed two major
clusters: one with northern populations and another one with
southern populations of Myanmar and those of Benin. A Mantel test
showed significant positive correlation between genetic and
geographical distances among populations. Analyses of Molecular
Variance (AMOVA) detected the highest genetic variation within
populations. The FST values were significantly different among all
teak populations and higher between than within the regions in
Myanmar. This study suggests applying different conservation
strategies for Northern and Southern Myanmar. | de |
