Figure 2.

Extracted megagametophytes from M. fraseri seeds stored for 6–66 months at 5°C and 20% RH showing a range of attributes and damage such as discolouration and browning. For each age class, seeds were initially subjected to a floatation test to separate sinkers from floaters, then megasporophytes manually extracted, visually assessed, weighed and placed into an oven to determine MMC. It was noted that most seeds that sank were white and intact (healthy) with minor browning appearing in the 42-month age class, while those that floated were all found to have various levels of damage with none determined to be viable, i.e. uniformly white and unblemished.
