Controlled deterioration for 36 h or longer reduced the final length and the rate of extension of both theplumuleand radicle.

The coleoptile is a protective cap that covers the "plumule" (precursor to the stem and leaves of the plant).

Increases in percentage germination and extension of theplumuleand radicle length occurred mostly in intermediate vigour seed samples.
From theCambridge English Corpus
Seeds were considered germinated when both theplumuleand radicle had extended to more than 2 mm.
From theCambridge English Corpus
Theplumuleand radicle length of 10 randomly selected seedlings in each replicate was measured after nine days.
From theCambridge English Corpus
There was a concurrent increase in the amount of tocopherol and the activity of superoxide dismutase in theplumule.
From theCambridge English Corpus
However, the hypocotyl-plumuleportions of the surviving seedlings were far less adversely affected by dehydration, and this was the criterion for categorizing seedlings as viable.
From theCambridge English Corpus
Mean germination time, germination rate andplumuleand radicle length were measured as described above.
From theCambridge English Corpus
No starch was found in the radicle, the coleoptile and theplumulein either dormant or non-dormant embryos (data not shown).
From theCambridge English Corpus
The correlations between these parameters were generally positive and highly significant except for radicle length (never significantly correlated with other parameters) andplumulelength (not always correlated with other parameters).
From theCambridge English Corpus
Plumuleand radicle lengths were not correlated.
From theCambridge English Corpus
Growth of theplumuledoes not occur until the cotyledons have grown above ground.
