Hybrids with abnormal development were obtained when particular
genotypes of Phaseolus vulgaris L. were crossed. The phenotypic
aberrations of the F₁s included retarded growth, chlorosis of the
trifoliate leaves and the formation of adventitious roots on the
hypocotyls. The expression of the abnormalities was dependent on the
temperature. At high...
An age-wave is upon us where many older adults are reaching retirement. Technically experienced older adults have skills that could be directly applied to free/open source software (FOSS) communities, such as project management, programming, and/or knowledge of a rapidly growing end-user population. FOSS is a widely popular, low-cost way to...
The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric SO stretching Q-branches observed by the latter are quite different, being especially complex for ³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...
L. C. Dunn (1893-1974) spent most of his scientific career conducting research in
developmental genetics as a member of the Zoology Department at Columbia
University in the City of New York. He had an accomplished scientific career
researching mutations in mice, which earned him respect from other geneticists and
scientists....
Studies were initiated to determine the response of two common
groundsel biotypes (Senecio vulgaris L. ) to several s-triazine herbicides.
Herbicides tested were: 2-chloro-4,6-bis(ethylamino)-striazine
(simazine), 2-chloro-4-(ethylamino)-6-(isopropylamino)-
s-triazine (atrazine) 2-(sec-butylamino)-4-(ethylamino)-6-methoxys-
triazine (GS-14254), 2, 4-bis(isopropylamino)-6-methoxy-striazine
(prometone), 2-(tert-butylamino)-4-(ethylamino)-6-methylthio-
s-triazine (terbutryn), and 2, 4-bis(isopropylamino)-6-
methylthio-s-triazine (prometryne). One biotype was much more
susceptible than the...
Renibacterium salmoninarum produces bacterial kidney
disease (BKD) in salmonid fish. Soluble antigen(s) (SA) produced
by the bacterium was characterized by physicochemical,
functional and immunological methods. The molecular weight
determination by SDS-PAGE analysis of SA yielded 14 different
molecular weight species. Seven of these species were
prominent, 57 kd protein being...
Field and laboratory tests were carried out to investigate the
survival of the root-nodule bacterium, Rhizobium trifolii, when
inoculated onto seeds of the pasture legume subterranean clover,
(Trifolium subterraneum L.), in order to improve the nodulation
and establishment of this plant in acid soils.
Field experiments were carried out in...
