| 内容記述 | Seeds of Pennisetum alopecuroides, Plantago asiatica, Setaria viridis, Setaria glauca, and Achyranthes Fauriei were collected from altitudinally different habitats, and, after germination on a constant temperature, freezing resistance in these seedlings was investigated. Freezing resistance, varying in degree according to each species, was intensified with the increasing elevation of the seed origin. In most species tested, freezing resistance was more intensitive on the seedlings derived from the Pacific Ocean side than Japan Sea side although the altitude of the seed origin was the same (about 30m) in both cases. The freezing resistance of P. alopecuroides seedlings was intensified by decreasing the incubation temperature for seed germination, but the difference in freezing resistance according to the altitude of the seed origin was never removed. The degree of freezing resistance in seedlings seems to vary according to the temperature level at the germination period, although the degree of resistance is determined by the environmental temperature of the original habitat. The varying level of freezing resistance seems to be a factor in permitting species-distribution into a new habitat, especially a higher or colder one. | |||||||
