YIELD STABILITY STUDIES IN SHORT-SEASON MAIZE. I. A DESCRIPTIVE METHOD FOR GROUPING GENOTYPES Tập 58 Số 4 - Trang 1029-1034 - 1978
Tsiboe Francis, L. W. Kannenberg
In recent years, several methods of identifying superior genotypes in the presence of genotype–environment interaction have been proposed. Fifteen single-cross maize hybrids, originating from a 6-inbred diallel of short-season maize, were grown in yield tests over 16 environments from 1969 to 1974. Several statistical methods for measuring yield stability were applied to the data. The pro...... hiện toàn bộ
Cadmium accumulation in crops Tập 78 Số 1 - Trang 1-17 - 1998
Cynthia A. Grant, Wayne T. Buckley, L. D. Bailey, F. Selles
Cadmium is a heavy metal present in soils from natural and anthropogenic sources. Plant uptake of Cd at levels present in the soil solution is dependent on a system that is largely metabolically mediated and competitive with the uptake system for Zn and possibly other metals. Much of the Cd taken up by plants is retained in the root, but a portion is translocated to the aerial portions of...... hiện toàn bộ
Agronomic and seed quality evaluation of Camelina sativa in western Canada Tập 86 Số 4 - Trang 1047-1058 - 2006
R. K. Gugel, Kevin C. Falk
Renewed interest in Camelina sativa is primarily due to the unique fatty acid profile of the seed oil and its potential value in industry, cosmetics and human nutrition. To exploit C. sativa in western Canada, more information is needed on the performance of this crop in this region. Following a preliminary evaluation in 2001, replicated agronomic trials were conducted in 2002 and 2005 wi...... hiện toàn bộ
CONTENT AND DISTRIBUTION OF TRYPSIN INHIBITORS AND HEMAGGLUTININS IN SOME LEGUME SEEDS Tập 60 Số 2 - Trang 695-701 - 1980
P. Valdebouze, Édith Bergeron, Therese Gaborit, J. DELORT-LAVAL
Cultivars of various legumes including fababean (Vicia faba L.), pea (Pisum sativum L.), lupin (Lupinus sp. L.), Vigna sinensis Endl. ex Haask vs. Vigna catjang Walp and soybean (Glycine max Meer) were tested for trypsin-inhibiting activity levels (TIA) and hemagglutinating (on trypsinised rabbit red blood cells) activity levels in hulls and cotyledons. TIA in these seeds as a percent of ...... hiện toàn bộ
Alternative oilseed crops for biodiesel feedstock on the Canadian prairies Tập 91 Số 5 - Trang 889-896 - 2011

Can. J. Plant Sci. 91: 889–896. Increased demand for biodiesel feedstock has encouraged greater napus canola (Brassica napus L.) production, but there may be a need for greater production of ot...... hiện toàn bộ
Influence of N supply on development and dry matter accumulation of an old and a new maize hybrid Tập 74 Số 3 - Trang 471-477 - 1994
D. E. McCullough, Philippe Girardin, Milica Mihajlović, A. Aguiléra, M. Tollenaar
The response of an old and a new maize (Zea mays L.) hybrid to N supply was evaluated under controlled-environment conditions. An old hybrid (Pride 5) and a new hybrid (Pioneer 3902) were grown at three N levels (15, 2.5, and 0.5 mM N), and development and dry matter accumulation were measured at the 4-, 8-, and 12-leaf stage. Leaf chlorophyll was monitored from the 8- to 12-leaf stage, a...... hiện toàn bộ
Root mass for oilseed and pulse crops: Growth and distribution in the soil profile Tập 89 Số 5 - Trang 883-893 - 2009
Yantai Gan, C. A. Campbell, H. H. Janzen, R. Lemke, L.P. Liu, Prakash Basnyat, C. L. McDonald
Crop roots transport water and nutrients to the plants, produce nutrients when they decompose in soil, and provide organic C to facilitate the process of C sequestration in the soil. Many studies on these subjects have been published for cereal crops, but little is known for oilseed and pulse crops. This study was conducted at Swift Current, Saskatchewan, in 2006 and 2007 to characterize ...... hiện toàn bộ
The biology of Canadian weeds. 142. Camelina alyssum (Mill.) Thell.; C. microcarpa Andrz. ex DC.; C. sativa (L.) Crantz. Tập 89 Số 4 - Trang 791-810 - 2009
Ardath Francis, Suzanne I. Warwick
This paper summarizes biological information on three cruciferous weed species: Camelina alyssum, C. microcarpa and C. sativa. Camelina sativa, which had been gathered or cultivated as an oil seed for many centuries in Europe, was the first to reach North America as a weed, towards the mid-19th century, gradually spreading across the prairies, mainly in crops, to British Columbia and the ...... hiện toàn bộ
Effect of Zn on the concentration of Cd and Zn in plant tissue of two durum wheat lines Tập 75 Số 2 - Trang 445-448 - 1995
Suman Choudhary, L. D. Bailey, Cynthia A. Grant, D. Leisle
Irrespective of fertilizer treatments, durum wheat (Triticum turgidum L. var durum) Cd concentration was lowest in the grain and highest in the roots and was in the order: root > leaf > stem > grain. Soil-applied Zn decreased the Cd concentrations in durum wheat grain, leaf, stem, and root. But, foliar application of Zn resulted in Zn loading of the leaf and stem and had little e...... hiện toàn bộ
