Plumule

The part bearing the tiny leaves was formerly, and is sometimes now, called the plumule, but is generally called the epicotyl, because it grows above or upon the cotyledons. ❋ Charles Landon Goodrich (N/A)

For our "plumule" we have also "gemmule", and French has both of these too. ❋ Unknown (2005)

The word "plumule" struck me; it turns out it's pronounced PLOOM-yule /"plu:myu:l/, and it means 'rudimentary shoot, bud, or bunch of undeveloped leaves in a seed' (it's from Latin plūmula, the diminutive of plūma 'small soft feather, down'), so that "shoots and plumules of one's experience" is a very tasty phrase, incorporating both the visible (as it were) and the embryonic shoots sprouting up from the depths of our lived lives and mulish memories. ❋ Unknown (2005)

Yet she insistently wanted to drop this one directly into nutrient soil, watch the epicotyl lengthen, smile proudly at the upward thrusting plumule, then fuss over stipule and first foliage. ❋ Ed Higgins (2011)

For some reason, I still maintain the awestruck wonder of a kinder planting beans pressed against the side of a jar so that the roots, hypocotyl, and plumule display, then watch in amazement as they burst through the ground and struggle toward the light. ❋ Ann Althouse (2009)

Thus the main divisions of flowering plants are founded on differences in the embryo,- on the number and position of the cotyledons, and on the mode of development of the plumule and radicle. ❋ Unknown (2006)

Sorghum, maize or millet grains or combinations are malted by soaking in water for one or two days, draining and allowing the seed to germinate for five to seven days until it has a distinct plumule. ❋ Unknown (1984)

The shooting down of the radicle or undeveloped root, and the springing up of the plumule or undeveloped stalk, is accordingly due to no vital principle in the seed, but to the complexity or entanglement of the molecules wrapped up in their integumentary environment. ❋ R. W. Wright (N/A)

In germination the two fleshy cotyledons of the Gingkgo remain within the shell, leaving the three-sided plumule to pass upward; the young stem bears its leaves in threes. ❋ Various (N/A)

The sheath which envelopes the radicle is called = coleorhiza = and that of the plumule, = pileole = or = germ-sheath =. ❋ K. Rangachari (N/A)

Pileole another name for germ-sheath, or the sheath covering the plumule in the grain, 18. ❋ K. Rangachari (N/A)

Here is the sweetest longitudinal section of the tentacle of an _Actinia_, and here -- look at these lovely transverse sections of the plumule of a pea; you can see the primary groups of spiral vessels. ❋ Harriet Stark (N/A)

The infrequency of turning the germinating grain benefits the growth of the roots and the development of the plumule, besides saving much labor. ❋ Various (N/A)

Germ-sheath a sheath enclosing the bud or the plumule in a grain, ❋ K. Rangachari (N/A)

The axis, which is differentiated into the plumule directed upward and the radicle downward, is small and straight and it is covered more or less by the edges of the scutellum. ❋ K. Rangachari (N/A)

It is important that the leaves on the primary axis arising from the plumule are examined. ❋ Unknown (N/A)

In the next step the calyx, more developed than usual, was separated from the corolla by a long peduncle, and the ovary, which was ovate, contained instead of a placenta a sort of plumule or young shoot. ❋ Maxwell T. Masters (N/A)

Thus the main divisions of flowering plants are founded on differences in the embryo, —on the number and position of the cotyledons, and on the mode of development of the plumule and radicle. ❋ Unknown (1909)

The same fact holds good with flowering plants, of which the two main divisions have been founded on characters derived from the embryo, -- on the number and position of the embryonic leaves or cotyledons, and on the mode of development of the plumule and radicle. ❋ Unknown (1859)

The same fact holds good with flowering plants, of which the two main divisions have been founded on characters derived from the embryo, — on the number and position of the embryonic leaves or cotyledons, and on the mode of development of the plumule and radicle. ❋ Charles Darwin (1859)
