The Effect Of Two Growth Retardant Chemicals, Cycocel And B-Nine, On Certain Nitrogeneous Components In Barley Seedlings, Linda Kinser

Masters Theses & Specialist Projects

Certain chemicals are known to inhibit growth in many plant species. These chemicals possess a common trait, the ability to inhibit stem elongation by suppressing the activity of the subapical meristematic region (11). These growth retardants have been extensively studied during the past several years in an effort to determine the biochemical mechanism responsible for reduction in plant height. The characteristic effect of these chemical retardants on the growth pattern has been described as producing plants with shorter, thicker stems and broader, darker green leaves. Tolbert, however, noted that although plants treated with the plant growth retardant, Cycocel, (2-chloroethyltrimethlammoniumchloride) and …

Biochemical And Morphological Analyses Of The Hordeum Jubatum-Brachyantherum-Caespitosum Hybrid Complex, Gareth Roz Babbel

Theses and Dissertations

Hordeum jubatum L., Hordeum brachyantherum nevski, and Hordeum jubatum var. caespitosum (Scribn.) Hitchc. Plants from sites in Utah and Idaho were grown and examined in order to determine whether or not hybridization with subsequent introgression occurs among the species and if so whether there is a difference in the relative amount of gene flow between the parent species H. jubatum and H. brachyantherum in different environments. Hybridizations and morphological analyses were made using standard procedures. Biochemical analyses were made by comparing paper chromatograms of leaf extracts of plant specimens. The results indicate that in Utah populations sampled, hybridization with subsequent …

Recommended Cereal Varieties : 1969, H M. Fisher, J. T. Reeves, J. A. Parish

Journal of the Department of Agriculture, Western Australia, Series 4

Cereal varieties widely recommended for growing in 1969 are Gamenya and Falcon wheats, Dampier and Beecher barleys and Swan oats.

Other varieties include the new wheat Darkan, which is recommended only for the higher rainfall areas, the rust resistant wheats Mengavi and Gamut, and Irwin oats for late sowing in northeastern districts.
