Abstract

An experiment was conducted to study the seed viability, dormancy and microflora, which are the constraints for production of tropical tree seedlings needed for afforestation. Tetrazolium test, one of the qualitative parameter for viability was found highly associated with field emergence of seed (r = 0.93). Hot water treatment to seed for three minutes and storing them in metal tin or polythene containers after cooling proved better seed germination in all the species studied. Microflora attack on seed could not be evaded even by seed dressing with organomercurial compounds in any of the species investigated.

Under the situations where seed availability of a species is a constraint, better seed germination may be achieved by i) improving seed dressing treatments, and ii) storing seeds in impervious containers to water such as tin or polythene bags after breaking the seed dormancy.
