Notes on some grasses XIX: systematic significance of microhairs on lodicules epidermis.
The osmotic water uptake of the lodicules from the ovary is hampered under dry conditions which impairs the swelling mechanism of the lodicules.
Mutations in the si1 locus result in the conversion of lodicules into lemma/palea.
In grasses it is a matter of convenience and tradition to identify as a spikelet the combination of one or more florets (each comprising a lemma, palea, lodicules, stamens, and pistil, or in certain grasses one or more of these parts absent) with two proximally situated bracts, the glumes (sometimes one or both absent).
The presence of a palea that subtends the flower and lodicules, these together subtended by a sheathlike bract called a lemma, is the rule in the grasses.
Tyto has medium-long and medium-wide kernels that have clasping lodicules with an incomplete horseshoe-shaped lemma base.
The kernels have colorless aleurones, medium long rachillas with short rachilla hairs, clasping lodicules, and horseshoe basal markings.
Its kernels have medium length and width with clasping lodicules, and horseshoe shape of basal markings.
Wheat florets have two lodicules at the base of the ovary, which function to open the floret at anthesis.
The development stage of florets at which emasculation was most easily accomplished was when the lodicules at the base of the ovary are swollen (Fig.
