Germinability Factors Of Field-Grown Sorghum Seed, D. B. Sauer, C. M. Christensen
Germinability Factors Of Field-Grown Sorghum Seed, D. B. Sauer, C. M. Christensen
Journal of the Minnesota Academy of Science
Germination of sorghum seed did not appear to be affected by spraying the plants with Maneb or with a chemical defoliant before harvest. Mechanical threshing greatly reduced germination of most but not all lots; this injury is thought to be related to the maturity and/ or moisture content of the seed when threshed, although other varietal differences may be important. At any given time there were large differences in moisture content between seeds of different hybrids, different plants of any one hybrid, and between different parts of the same panicle.
Germination Of Seeds Of Perennials Native To The Minnesota Region, May L. Wright
Germination Of Seeds Of Perennials Native To The Minnesota Region, May L. Wright
Journal of the Minnesota Academy of Science
Requirements for the germination of the seeds of herbaceous perennials native to the Minnesota region are given in general. Examples of specific requirements are noted for certain plant species.
Germination And Early Development Of The Silky Prairie Clover, Richard B. Forbes
Germination And Early Development Of The Silky Prairie Clover, Richard B. Forbes
Journal of the Minnesota Academy of Science
Field and laboratory studies of the silky prairie clover (Petalostemon villosum Nutt.) in central Minnesota indicated that seeds of this plant require scarification but do not require an overwintering period, to germinate. Germination and primary root growth are rapid; shoot growth appears to be quite slow. Methods of associating shoot growth with age are suggested and several notes on the life history of the plant ore presented.
The History Of Germinating Embryos Of The Eastern Dwarfmistletoe (Arceuthobium Pusillum Peck), Frank H. Tainter
The History Of Germinating Embryos Of The Eastern Dwarfmistletoe (Arceuthobium Pusillum Peck), Frank H. Tainter
Journal of the Minnesota Academy of Science
Embryos of germinating seeds of Arceuthobium pusillum have four histological zones: the protoderm of the radicular apex, which remains distinct throughout germination and through anticlinal divisions gives rise to the epidermis; the procambium, which matures into a simple vascular strand in the mature radicle; the ground meristem, which matures into the cortex; and the promeristem, from which the procambium and ground meristem are derived.

The Influence Of Soil On Germination Of Fungus Spores, Roy D. Wilcoxson
The Influence Of Soil On Germination Of Fungus Spores, Roy D. Wilcoxson
Journal of the Minnesota Academy of Science
Soil prevents spores of many fungi from germinating, according to reports from different parts of the world. Thus Welsh soils were reported to be fungistatic to several fungi (Dobbs, 1953). Jackson (1958) made a similar report about Nigerian soils. In Minnesota Fusarium oxysporium f. lini (Bolley) Sny. and Han. persists in soil devoid of host debris but Helminthosporium sativum P.K.B. does not (Anwar, 1949). A more thorough study of the influence of Minnesota soils on germination of fungus spores would provide additional information on ecology of fungi and might suggest control measures for certain pathogens. Such a study may be …
