Abstract
A comprehensive laboratory study entitled “Influence of pre- sowing treatments on seed germination and seedling quality in Canes.” was undertaken at Department of Forest Biology and Tree Improvement, College of Forestry, Sirsi, University of Agriculture Sciences, Dharwad during 2014-15. Different chemical and non-chemical, physical and other pre-sowing seed treatments were tried to study the effect of presowing treatments on seed germination and seedling qualities.  Fresh seeds of Calamus thwaitesii and Calamus nagabettai were used separately for each treatment with three replications using CRD design. The pre-sowing treatments exhibited significant differences in seed germination percentage in both the species. The maximum germination of 91.33 per cent and 61.00 per cent was recorded in removal of sarcotesta treatment in Calamus thwaitesii and Calamus nagabettai respectively. The increase in germination percentage due to removal of sarcotesta was 30.67 and 40.00 per cent over the control in both the species respectively. The higher mean daily germination values of  1.78 and 1.22 and peak values  of 1.87  and 1.24 were observed in removal of sarcotesta in Calamus thwaitesii and Calamus nagabettai respectively.  Similarly speed of germination was significantly higher in all the pre sowing treatments compared to control. The  pre-sowing treatments had significant influence on seedling length and root length during experimentation. Maximum shoot length at the end of germination period was found to be 12.95 cm and 9.53 cm which were recorded in sarcotesta removal treatment in Calamus thwaitesii and Calamus nagabettai respectively. The same treatment has showed significantly higher seedling vigour index of 3159 in Calamus thwaitesii and 1214 in Calamus nagabettai.
