Abstract:: ... The effect of activated charcoal (AC) on the germination of botanical potato seeds was tested by applying AC to seeds in petri dishes which had been pretreated with gibberellic acid (GA). A diverse sample of accessions including cultivar and cultivated species germplasm, cultivated species hybrids, wild species, and wild species known for their slow germination was tested. The time required from h ...

Abstract:: ... A study of Luzula spicata seeds from the alpine tundra of the Colorado Front Range revealed complete dormancy due to a condition of the seed coat or endosperm. Dormancy appears to be related to the presence of a hard waxy layer (gelatinous sheath when imbibed) covering the entire seed surface. The only seed treatment effective in breaking dormancy in this species is scarification on the micropylar ...

Abstract:: ... I examined the role of germination cueing in the dynamics of Erodium botrys and E. brachycarpum populations exposed to localized, spatial variation within Californian annual grasslands. In laboratory trials, germination rates of both species increased significantly in seeds previously exposed to fluctuating temperatures (25—45°C) during dry storage. Temperature fluctuations per se were more import ...

Abstract:: ... Inhibitors localized at the micropyle and interacting with gibberellin impose dormancy on seeds of both Luzula spicata and L. parviflora from the Colorado Front Range. Removal of the inhibition by precise scarfication elicits germination in both species. Luzula spicata seeds lacking precise scarification were found germinated in tundra soil. Germination was experimentally induced in L. spicata by ...

Abstract:: ... Germination tests were made on the seeds of various farm crops adapted to Colorado conditions which had been stored in a dry, unheated room for periods varying from 1 to 15 years. The germination percentage of wheat, oats, and barley declined slowly for the first 10-year period with a sharp break in germination between the tenth and twelfth years. The drop in germination was as great or greater fr ...

Abstract:: ... The alpine flora of the Sierra Nevada has developed relatively recently and largely in situ from western American sources. The Sierra thus provides a good site for an attempt to answer the question: "How does an alpine flora originate?" The primary study area was a transect from the desert near Bishop, California (1,400 m), to Piute Pass in the Sierra Nevada (3,540 m). Upward along the transect th ...
