(2002-10-17)African rue is a toxic and highly invasive plant found in western parts of Texas. This publication describes the plant and explains the symptoms it can cause in livestock that ingest it. There are suggestions for controlling ...
-
(Texas A&M University. Libraries, 1982)A laboratory technique utilizing a thermogradient plate was used to determine the effect of temperature extremes on germination of different Sorghum bicolor (L.) Moench genotypes and the inheritance of base temperature. ...
-
(Texas A&M University. Libraries, 1986)Three crop moisture stress indices (CMSI1, CMSI2 and CMSI3) are proposed. In computing index 1 and 2, stress is assumed to occur when the actual to potential transpiration ratio (AT/PT) falls below a critical level, while ...
-
(Texas A&M University. Libraries, 1989)Population samples of Schizachyrium scoparium, collected from Texas (vars. divergens, frequens, littorals, and virile) and New Mexico (var. neomexicanum), and herbarium specimens (including type specimens of Andropogon ...

(2005-10-31)Greenbriar can become a problem on rangelands and croplands. The basal stem spray method described in this publication will control greenbriar effectively. There are instructions for preparing the herbicide mix and for ...
-
(Texas A&M University. Libraries, 1988)Evidence is presented here for stress-induced changes in gene expression and the specificity of plant metabolic responses to applied stress. Analysis of changes in the rate and pattern of protein synthesis in slash pine ...
-
(Texas A&M University. Libraries, 1977)An early and late maturing sorghum genotype, 60M and 90M respectively, were analyzed to determine the endogenous levels of IAA, ABA, and gibberelllns. Previous experiments had Indicated that the gibberellin, GA3, hastens ...
-
(Texas A&M University. Libraries, 1983)Chilling susceptibility and symptoms were reported for 31 genera in 18 families, showing widespread sensitivity to chilling injury among foliage plants. Electrolyte leakage was positively correlated (r = 0.97, 0.98) with ...
-
(Texas A&M University. Libraries, 1987)Two ecotypes of S. halepense (ALA,NM) were used to compare NaCl resistance with cultivar, BTX-HEG, of S. bicolor. The objectives were: (1) to compare NaCl resistance between the two Sorghum species with whole plants and ...
-
(Texas A&M University. Libraries, 1981)The valve morphology of twenty four taxa of the genus Eunotia from Texas and Alaska was examined with the light and scanning electron microscopes with particular emphasis on the terminal nodules, raphe, hyaline areas, ...
-
(Texas A&M University. Libraries, 1979)Percent infection and gain per cycle of selection were compared after two cycles of mass selection with progeny test, mass selection without progeny test and S1 selection in breeding for resistance to sorghum downy mildew ...
-
(Texas A&M University. Libraries, 1979)The concept o f a plant's immunity to virus disease implies a lack of infection as well as in ability of the virus to replicate. Plants having subliminal or latent virus infections are often considered immune. Microscopic ...
