| Abstract/Contents: | "Native turfgrasses have received greater attention in recent years because of their usefulness in growing in areas where many other grasses cannot. Saltgrass (Distichlis spicata) has good salt tolerance, but the natural germination rate for the seed is low. This is mostly due to the thickness of the seed coat inhibiting normal imbibition of water. Previous research in our laboratory has demonstrated increased germination with hand-scarification. The purpose of this research was to compare germination rates of machine-scarified, hand-scarified, and nonscarified seed. Scarifying the seeds by hand results in greater uniformity, but the operation is tedious and time-consuming. Machine scarification is quick, but the seeds have reduced uniformity. Two seed lots, one designated "Modoc" and one designated "Granite", were compared in laboratory and field germination tests. Preliminary observations have shown that "Granite" seed had somewhat higher viability and vigor than the "Modoc" seed. Significantly greater germination occurred with scarification when seeds were germinated at 14h of light at 30 °C and 10 h of darkness at 20 °C in the laboratory. Although scarification treatments were similar with the "Granite" seeds, near 80% germination, there were significant differences between hand and machine scarification with the "Modoc" seeds; hand scarified seed had greater germination. The field germination experiment had similar results to the laboratory experiments with "Granite" seed. However, scarification did not aid germination of "Modoc" seed. This is thought to be due to low vigor and associated death of seedlings prior to emergence. Preliminary data confirm the low vigor of the "Modoc" seed as compared to "Granite" seed." |
