YIELD STABILITY STUDIES IN SHORT-SEASON MAIZE. I. A DESCRIPTIVE METHOD FOR GROUPING GENOTYPES
Canadian Journal of Plant Science - Tập 58 Số 4 - Trang 1029-1034 - 1978
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
problems wit...
CONTENT AND DISTRIBUTION OF TRYPSIN INHIBITORS AND HEMAGGLUTININS IN SOME LEGUME SEEDS
Canadian Journal of Plant Science - Tập 60 Số 2 - Trang 695-701 - 1980
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 that in d...
IMPACTS OF FREEZING TEMPERATURES ON CROP PRODUCTION IN CANADA
Canadian Journal of Plant Science - Tập 67 Số 4 - Trang 1167-1180 - 1987
Subzero temperatures are the most widespread hazard to crop production in
Canada. This hazard ranges from temperature occurrences near 0 °C in spring and
fall that damage many annual crops and some perennials to the winter occurrences
of −30 °C and lower that damage or kill vegetative and/or reproductive tissues
of some perennial species. Terminology, types of freeze damage, and the freeze
risk ar...
Influence of N supply on development and dry matter accumulation of an old and a new maize hybrid
Canadian Journal of Plant Science - Tập 74 Số 3 - Trang 471-477 - 1994
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, and
leaf p...
Identification of a quantitatively inherited source of Hordeum bulbosum derived scald resistance from barley line 926K2/11/1/5/1
Canadian Journal of Plant Science - Tập 84 Số 3 - Trang 935-938 - 2004
Scald resistance breeding requires identification and incorporation of novel
resistance sources into local breeding populations. A New Zealand barley Hordeum
vulgare L.) line (926K2/11/1/5/1) was evaluated in scald [Rhynchosporium secalis
(Oud.) J.J. Davis] nurseries at Lacombe and Edmonton, Alberta, Canada, as a
potential source of scald resistance derived from H. bulbosum. Primary
objectives wer...
Forage-corn production and N-fertilizer replacement values following 1 or 2 years of legumes
Canadian Journal of Plant Science - Tập 73 Số 2 - Trang 477-493 - 1993
The costs of N fertilizer and concern for sustainable agriculture have led to
renewed interest in the use of legumes as a source of N for succeeding
non-legume crops. In this regard, field experiments were conducted in 1987,1988
and 1989 on a Rivière-du-Loup sandy gravelly loam (Ferro-Humic Podzol) at
St-Anselme and on a Chaloupe silty loam (Orthic Humic Gleysol) at Deschambault
in eastern Quebec,...
PLANT-TO-PLANT VARIABILITY OF MAIZE PLANTS GROWN AT DIFFERENT DENSITIES
Canadian Journal of Plant Science - Tập 63 Số 1 - Trang 45-59 - 1983
Development of plant-to-plant variability in plant height, flowering
characteristics and grain yield was studied in two maize (Zea mays L.) hybrids
grown over 2 yr at 62 000, 93 000 and 124 000 plants/ha. The purpose of the
research was to provide fundamental data on patterns of interplant variability
in maize, as a foundation for more applied studies on effects of cultural
practices on within-cro...
RAPID DETERMINATION OF SEED GERMINATION POTENTIAL TO MEASURE QUALITY LOSS IN STORED WHEAT
Canadian Journal of Plant Science - Tập 62 Số 4 - Trang 1045-1048 - 1982
A rapid method of determining wheat seed germination after 1 day (G1) of
incubation was found. Germination of wheat seed stored at [Formula: see text]
moisture content is estimated by adding 12% to G1; at <17% moisture content
germination is not consistently predicted by G1.
Changes in kernel characteristics during grain filling in silage-specific and dual-purpose corn hybrids
Canadian Journal of Plant Science - Tập 92 Số 3 - Trang 427-439 - 2012
Ma, B. L. and Dwyer, L. M. 2012. Changes in kernel characteristics during grain
filling in silage-specific and dual-purpose corn hybrids. Can. J. Plant Sci. 92:
427–439. Silage-specific corn (Zea mays L.) hybrids have been gaining in
popularity in recent years, but there is a lack of information about the
difference in kernel characterization between Leafy silage-specific and
dual-purpose hybrids....
EFFECTS OF TEMPERATURE ON RATE AND DURATION OF KERNEL DRY MATTER ACCUMULATION OF MAIZE
Canadian Journal of Plant Science - Tập 68 Số 4 - Trang 935-940 - 1988
The response of rate and duration of kernel dry matter accumulation to
temperatures in the range 10–25 °C was studied for two maize (Zea mays L.)
hybrids grown under controlled-environment conditions. Kernel growth rates
during the period of linear kernel growth increased linearly with temperature
(b = 0.3 mg kernel−1 d−1 °C−1). Kernel dry weight at physiological maturity
varied little among tempe...
