Variation in wood physical and anatomical properties of anjily (Artocarpus hirsutus LAM.) grown in different agro-climatic zones of Thrissur district, Kerala - Vellanikkara Department of Wood Science, College of Forestry 2015 - 102p
MSc
A study entitled “Variation in wood physical and anatomical properties of
Anjily (Artocarpus hirsutus Lam.) grown in different agro-climatic zones of Thrissur
district, Kerala” was conducted in the College of Forestry, Kerala Agricultural
University, Vellanikkara, Thrissur during the period 2015-2017. The present
investigation was conducted with the objective to assess the variation in wood
anatomical and physical properties of anjily (Artocarpus hirsutus Lam.) grown in
different agro-climatic zones (Coastal sandy, Central mid land and Malayoram) of
Thrissur district, Kerala and to compare the anatomical and physical property of
wood between plantations and homesteads.
Samples from anjily trees were selected from the three agro-climatic zones of
Thrissur district following stratified random sampling technique. The experimental
materials were collected from three agro-climatic zones (9 Costal sandy + 9 Central
midlands + 9 Malayoram) which also include trees from three girth classes viz., 50-
100 cm, 100-150 cm. and more than 150 cm. Wood samples of three trees were
collected from each girth class. Wood samples were also collected from three
plantations in Thalassery taluk of Kannur district. Analysis revealed that some of the
anatomical properties were significantly different between girth classes across three
agro-climatic zones. Basic density, moisture content, heartwood colour, vessel
frequency, vessel area, vessel diameter, ray width, fibre wall thickness and fibre
lumen diameter did not show significant difference across three agro-climatic zones.
Ray frequency, ray height, ray width and fibre lumen diameter showed significant
difference between three girth classes across the zones. Analysis revealed that there
was significant differences in vessel frequency, vessel diameter, vessel length, ray
width, fibre length, fibre lumen diameter, moisture content and basic density between
homesteads and plantation.
Ecoanatomical characters like vulnerability index and vessel mesomorphy were
also analysed and vulnerability index was found to be highest in central mid land.
Mesomorphy values of anjily wood indicated that it was mesic in nature. Correlation
analysis also showed that basic density was positively correlated with moisture
content, ray height, fibre length and fibre wall thickness. The wood properties of
anjily was also found to be comparable to teak wood in various aspects
