Germination and storage behavior of Phoebe goalparensis Hutch. seeds
Experiments were conducted in Phoebe goalparensis to study (1) the influence of seed coat on germination, (2) the seed response to desiccation and (3) the storability of the seeds. Here dormancy of seed is a result of an impermeable seed coat that prevents water absorption and growth of the embryo. Manual removal of the seed coat was found to be the best pretreatment for viability test. The seeds were also desiccation sensitive and at 29% and 31% whole seed and embryo moisture content respectively, germination was significantly reduced due to desiccation damage. For large scale pretreatment, drying to 32% moisture content may be effective for improvement of germination of intact seeds. Storage experiments showed that the best survival (70%) could be achieved after twelve months hermetic storage at 5°C and 33% moisture content.
