Eksempler på plumule

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

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

• In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure.

• Increases in percentage germination and extension of the plumule and radicle length occurred mostly in intermediate vigour seed samples.

• Seeds were considered germinated when both the plumule and radicle had extended to more than 2 mm.

• The plumule and radicle length of 10 randomly selected seedlings in each replicate was measured after nine days.

• There was a concurrent increase in the amount of tocopherol and the activity of superoxide dismutase in the plumule.

• However, the hypocotyl-plumule portions of the surviving seedlings were far less adversely affected by dehydration, and this was the criterion for categorizing seedlings as viable.

• Mean germination time, germination rate and plumule and radicle length were measured as described above.

• No starch was found in the radicle, the coleoptile and the plumule in either dormant or non-dormant embryos (data not shown).

• The correlations between these parameters were generally positive and highly significant except for radicle length (never significantly correlated with other parameters) and plumule length (not always correlated with other parameters).

• Plumule and radicle lengths were not correlated.

• Growth of the plumule does not occur until the cotyledons have grown above ground.

• The embryo forms a ligule, and the plumule protrudes from this.

• Here the hypocotyl is a rudimentary axis between radicle and plumule.
