Weedy strains and cultivars with moderately to strongly dormant intact seeds were further evaluated for germination of nonafterripened caryopses (dehulled seeds), caryopses with the pericarp/testa removed, and excised embryos to estimate the effect of tissue components on dormancy.
The position of the caryopsis from which the mother plant originated also has an influence on the germinability of the caryopses of the next generation or even later generations [Datta et al., 1972; Gutterman, in press(a)].
Cupule removal followed by gibberellic acid application resulted in germination within 10% of all viable caryopses (Tian et al., 2003).
Using 'Bison' buffalograss bare caryopses, a 1-ha area was seeded at the rate of 3.5 kg [ha.sup.-1] under a center pivot irrigation system in June 1997.
Immature caryopses from spikes of all cultivars were removed at the same time for each replication.
Low molar solutions of gibberellic acid increased the germination of gamagrass caryopses removed from the cupules, but had only small effects on dormancy when caryopses remained in the cupules (Anderson, 1985; Tian et al., 2003).
The cultivar N22 was selected because, of the cultivars, its seeds and caryopses (hull removed) displayed the strongest dormancy.
However, establishing a mechanical system to remove the cupule and scarify the pericarp without damaging the caryopses may be difficult.
MOST OAT CULTIVARS have hulled grain, with the hulls (lemmas and paleas) remaining adhered to the groats (caryopses) when the grain is harvested and threshed.
However, separating empty from fertile florets with a seed blower was difficult for many samples of Summer from Highmore because of shriveled caryopses in the fertile florets.
The florets were dissected and the caryopses were measured and photographed under a stereoscopic microscope to document their characteristics and developmental stage.
