regard to match manufacture. Twenty Candidate plus trees (CPTs) were selected
from 10 panchayats across two districts (Thrissur and Palakkad) in Kerala to study
the variation in wood properties and the growth parameters of their half-sib
progenies during 2013-2017. Core samples were collected to analyse the anatomical
properties and fibre indices between the CPTs, which was later found to vary
significantly at one percent level. Morphological and growth parameters were
observed in the half-sib progenies of the selected trees both in nursery and field
condition for 150 days each. The morphological parameters like height, collar
diameter, root length, leaf area, number of leaves etc. were found to vary
significantly at nursery but not throughout the study period. Relative Growth Rate,
Absolute Growth Rate and Net Assimilation Rate did not show significant variation
among the seed sources. Field performance of the progenies was evaluated at
Aaramkal, Vellanikkara, Thrissur, Kerala in RBD. Height and collar diameter
varied significantly initially but the differences were not significant for collar
diameter from 90 days after planting. However, survival percentage did not show
any significant difference between the progenies. FCV AT 1 showed the maximum
height growth at 150 days after planting. A questionnaire survey was conducted to
access farmers’ perception towards growing raw materials for match manufacture.
The respondents had an overall positive approach toward tree farming. The majority
of the respondents were confident that scientific guidance will help them in
increasing the yield.
