What's the difference between rachilla and spikelet?

Rachilla


Definition:

  • (n.) Same as Rhachilla.

Example Sentences:

  • (1) Recessive inheritance was marked for short rachilla hairs.

Spikelet


Definition:

  • (n.) A small or secondary spike; especially, one of the ultimate parts of the in florescence of grasses. See Illust. of Quaking grass.

Example Sentences:

  • (1) Small transient all-or-none depolarizations (also termed in the literature fast prepotentials, spikelets, pseudospikes, d-spikes, or short latency depolarizations) and their association with lucifer yellow (LY) dye-coupling were analyzed in CA1-CA3 hippocampal pyramidal cells in urethane anesthetized rats.
  • (2) The isolates were grown on Sabouraud glucose agar for 2 days before being inoculated into boiled spikelets of Axonopus compressus (Gramineae) and then into induction medium (IM).
  • (3) Spikelets rose from base line as 3-10 mV depolarizing wavelets with a duration between 5 and 10 ms.
  • (4) The action potentials and the subthreshold spikelets were shown to be Na+ dependent and are presumably generated by a voltage-dependent inactivating Na+ conductance.
  • (5) Hooked macrohairs on the lemma of the spikelet show that morphological modifications in grasses for dispersal by attachment to the surface of animals were present in the Late Eocene.
  • (6) flower glume colour, degree of lateral spikelets development, hairy rechis of the ear, were observed in diallel crosses among the varieties Nutans 244, Trumpf, DZ-02389, Hiproly and Brachitic.
  • (7) Plateau potentials with a high threshold and high-threshold spikelets were Ca2+ dependent and seem to be generated by non-inactivating and possibly inactivating Ca2+ conductances.
  • (8) Relay cells, on the other hand, were strongly depolarized and fired spikelets at a greatly increased frequency during EOD-interruptions.
  • (9) It was found that (a) 15 of the 24 LY-injected pyramidal neurons (63%) showed dye-coupling; (b) spontaneous, anti- and orthodromically evoked spikelets (3-7 ms in duration; 3- to 12-mV peak) were recorded in 40 of 95 cells (42%); (c) there was a significantly higher probability of dye-coupled neurons with spikelets and of uncoupled ones without spikelets; (d) spikelet waveform and amplitude were unaffected by spontaneous or imposed polarizations; (e) large hyperpolarizations could reduce the rate and even prevent spikelets; and (f) spikelets could precede or follow spikes, the latter were more frequent with large depolarizations.
  • (10) Electrophysiological findings, and the association of dye-coupling and spikelets, suggest strongly that at least some spikelets are coupling potentials.
  • (11) Discovery of a female spikelet of the grass genus Pharus (Gramineae: Bambusoideae: Phareae) in association with mammalian hair in Dominican Republic amber provides the first fossil evidence of epizoochory.
