Responses of Short period ring width and mean vessel area Chronologies of Plantation grown teak (Tectona grandis L. f.) to Climate in Thrissur, Kerala, India

摘要

Investigations on relationship between short period chronological characters (ring width, mean vessel area) and climate (rainfall, temperature) offour teak (Tectona grandis L. f.) plantations in Thrissur district, Kerala were carried out. Ring width index chronologies were positively correlated with the previous year monsoons (south west and north east) and annual rainfall whilemean vessel area index (MVA) chronologies showed significant positive correlation with the previous year south west monsoon, north east monsoon, annual rainfall, previous year October-November temperature, October-November temperature and annual temperature. It can be concluded that short period tree ring chronologies of teak have good potential for dendroclimatic reconstruction for Kerala.
