Abstract

Dendrocalamus brandisii is a very large evergreen bamboo, which is commonly used for house building, for making baskets, handicrafts and furniture. Young shoots of D. brandisii are edible. Although, abundant seed production is observed during gregarious flowering, viability of seeds under natural conditions is very short. In the present study, accelerated ageing test was carried out to predict the storability of seeds. Seeds were subjected to accelerated ageing at 42±1°C with a relative humidity of 100% for 0, 1, 3, 5 and 8 days, in a covered water bath. Germination test and biochemical analyses were carried out for control and aged seeds. The initial germination percentage was 59.71% and after accelerated ageing germination declined to 15.39%. Total soluble proteins, sugars and starch content decreased during the ageing process. There was a gradual decrease in the activity of acid and alkaline phosphatase and peroxidase, while the activity of -amylase and -amylase increased during accelerated ageing. Hence the decrease in the viability of D. brandisii seeds may be due to the changes in the biochemical content and the activity of enzymes involved in the degradation of seed reserves.
