Freezing resistance of tissues in the twig of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Alden, John Norman
Abstract:: The relative freezing resistance of tissues in the stem, foliage and buds of terminal twigs from Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) was investigated at about ten-day intervals from summer until the following spring. Tissues from growing twigs collected before development of dormancy had no freezing resistance and were killed immediately...

Effects of three plant growth regulators upon growth patterns in seedlings of three races of Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco

Creator:: Rietveld, W. J.
Abstract:: Populations of Douglas-fir seedlings from interior British Columbia, Vancouver Island, and Arizona received six bi-weekly foliar spray applications of the growth regulators IAA, CCC, and B-995, each at three concentration levels under controlled environmental conditions. Large differences were found among the three populations in their responses to the growth regulators....

Development of oven and Karl Fischer techniques for moisture testing of grass seeds

Creator:: Benjamin, Ethan
Abstract:: Seed moisture is a primary factor influencing seed quality during harvesting, storage, and marketing of grass seed. However, the Association of Official Seed Analysts' Rules for Testing Seeds do not contain methods for moisture testing. The oven methods in use by seed testing laboratories in the U.S. are diverse and...

Stimulation of plant growth by sub-lethal concentrations of herbicides

Creator:: Wiedman, Steven John
Abstract:: Studies were conducted to determine the extent and nature of sub-lethal effects of herbicides on plant growth. At least one herbicide from each major chemical class of herbicides was evaluated under greenhouse conditions. Oat plants were grown in sand culture to eliminate soil interferences. Herbicides were applied pre-emergence in nutrient...

Control of cytokinin autonomy in Phaseolus lunatus callus cultures

Creator:: Kim, Sang-Gu
Abstract:: The ability of N,N'-diphenylurea (DPU) to substitute for cytokininactive adenine derivatives in promoting callus growth of Phaseolus lunatus and Nicotiana tabacum has been examined. In general, DPU stimulated callus growth of P. lunatus at high concentrations and the growth of most callus tissues was irregular, while the response of tobacco...

Growth and forage quality of tall fescue (Festuca arundinacea schreb.) and perennial ryegrass (Lolium perenne L.) as affected by mefluidide

Creator:: Manurung, Sabam Oloan
Abstract:: Field study with 5 tall fescue genotypes treated at the vegetative growth stage, with 0, 0.28, 0.56, and 0.84 kg/ha of mefluidide was initiated in July, 1980. The regrowth of these plants were again treated at the booting growth stage in April, 1981, with the same rates of mefluidide as...

Acid hydrolases and seed shriveling in triticale seeds

Creator:: Lin, Tsan-piao
Abstract:: The tissue and substrate degradational enzymes, acid hydrolases, in endosperm were studied in order to discern the mechanism of seed shriveling in triticale (XTriticosecale Wittmack). Acid hydrolases in crude extract of 7-week-old developing endosperm of 2 lines each of triticale with shriveled (6TB,JZBS) and plump seeds (6TA, RBP) were successfully...

A preliminary investigation into the use of the tarif system and three tree selection methods for obtaining Douglas-fir stand and stock tables from large-scale aerial photography

Creator:: McCadden, Richard Jay
Abstract:: As a preliminary step toward the establishment of a 70 mm. aerial photo timber inventory system capable of generating accurate stand tables, stock tables, and gross volume estimates, this project focuses on the development of a system which (1) eliminates the need to measure tree height on the photos through...
