Tree growth climate relationship in plantation teak (Tectona grandis L.f.) grown in Thrissur district, Kerala - Vellanikkara Academy of Climate Change Education and Research 2015 - 62 pages
MSc
The present study ―Tree growth climate relationship in plantation teak
(Tectona grandis L. f.) grown in Thrissur District, Kerala‖ was conducted to develop
tree-ring chronologies from plantation teak (Tectona grandis ) at the site Vazhani in
Thrissur forest division, Kerala, to understand the relationship between climate and
tree growth. The work was carried out at the Department of Wood Science, College
of forestry, KAU, Vellanikkara, Thrissur.
The study samples were selected from the sample collection in the
Department of Wood Science, College of Forestry. The collected samples are thinned
and sanded with different grades of sand papers to expose the growth rings. Statistical
parameters like SNR (Signal to Noise Ratio) and EPS (Expressed Population Signal)
showed a good dendroclimatic potential. Weather parameters such as rainfall,
temperature and moisture index showed significant positive and negative correlation
with Ring Width Index. Summer temperature, showed significant positive correlation
and annual temperature showed negative correlation. South West monsoon rainfall
showed significant positive correlation. Correlation between Ring Width Index and
Moisture Index showed positive correlation during previous year North East
monsoon.
