Influence of Seed Moisture Content on Seed Germination and Quality in Canes
Journal Title: Journal of Plant Science and Research - Year 2016, Vol 3, Issue 2
Abstract
A comprehensive laboratory study entitled “Influence of seed moisture on germination and seed quality in in Canes: Calamus thwaitesii and Calamus nagabettai” was undertaken at the Department of Forest Biology and Tree Improvement, College of Forestry, Sirsi, During 2014-15.The initial fruit moisture content was 48.72 per cent and 31.52 per cent and the germination of fresh fruits was found to be 61.33 and 38.66 per cent in Calamus thwaitesii and Calamus nagabettai respectively. Subsequently there was much difference in germination per cent in response to reduction in moisture content while drying the seeds. Significantly higher moisture content was observed in fresh seeds in both the species i.e. immediately after collection. Lowest moisture content was observed in seeds dried for 30 days drying under shade. The moisture content of 30.61 per cent and 18.15 per cent was found to be critical moisture content for seeds as below this germination was zero in Calamus thwaitesii and Calamus nagabettai respectively. Higher germination (61.33 per cent) and germination parameters were observed in seeds immediately after collection (T1). The lowest germination (20.00 per cent) was observed in seeds dried for 15 days drying under shade (T4) in Calamus thwaitesii. In Calamus nagabettai, T1 treatment recorded significantly higher germination (38.66 per cent). The lowest germination (14.66 per cent) was observed in seeds dried for 10 days drying under shade (T3). In general, moisture content of seeds was decreased with increasing drying period and leads to decline in seed germination and seed quality parameters in both the species and effect was more pronounced in Calamus nagabettai compared to Calamus thwaitesii.
