In contrast, naked caryopses (i.e., with the cupulate fruit case removed) germinate readily (Anderson, 1985).
Thus, we need to understand the role the cupulate fruit case plays in dormancy of eastern gamagrass.
We conducted an experiment to find the role of the cupulate fruit case on seed dormancy.
An experiment was conducted to determine the effect of moist prechill on the force required to open the cupulate fruit case.
Determined on the basis of the equation and data, the rate of decline in the force required to open the cupulate fruit case does not change significantly after 4 wk of prechill.
22 mm long (including the petals), sessile, densely arranged, odorless; sepals subsymmetrical, narrowly subtriangular-lanceolate, apex acuminate, 16-18 x 4 mm, free, entire, pale colored, densely and coarsely white-lepidote toward the apex with fimbriate trichomes, the adaxial ones alate-carinate with keels decurrent on the ovary, the abaxial one carinate or nearly so; petals spathulate, obtuse-cucullate, emarginate, 17-18 x 5-6 mm, erect except for the suberect apex at anthesis, greenish at the basal 2/3 and white at the apical 1/3, bearing 2 upwardly to downwardly oriented, cupulate
