THE EFFECT OF STORAGE ON GROWTH AND YIELD OF GINGER (ZINGIBER OFFICINALE RESCOE)

Storage of "seed pieces" of ginger (Zingiber officinale Rescoe) for 0, 21, 35 and 42 days showed that, in general, the number of days to germination decreased with length of storage period while percentage germination and yield increased from 0 to 42 days storage.

However, germination and yield were consistently lower after 35 days storage than after 21 days.

This anomalous behaviour may be due to secondary dormancy during which the seed pieces lost their dormancy up to 21 days of storage but regained or entered into secondary dormancy at 35 days and again lost dormancy at 42 days.
