Weight gain is associated with deterioration in metabolic health, whereas weight loss improves insulin sensitivity. This study assesses the impact of long-term, successfully maintained and weight-loss relapse on measures sensitivity identifies factors that explain variability sensitivity.Women (20-45 years) were recruited into four groups: reduced-overweight/obese (RED, n=15); body mass index (BMI)-matched controls (stable low-weight, n=19), BMI⩽27 kg m-2; relapsed-overweight/obese subjects...
Soybean [ Glycine max (L.) Merr.] production in short‐season areas has increased greatly because of improvements cultivars and practices. Previous studies genetic improvement soybean have reported yield increases 0.5 to 1% per year. To evaluate the germplasm, 41 ranging from maturity group 000 0, released 1934 1992, were grown for 8 station‐years Ontario Quebec. Yield, maturity, plant height, lodging score, 100‐seed weight, seed protein oil levels, stability regressed on year release...
In three of five cases, tassel removal from corn ( Zea mays L.) at or near emergence increased grain yields. The increase was larger and more consistent higher populations. When leaf tissue removed with the tassel, yields were decreased, although this effect smaller A large portion yield response detasseling resulted elimination light interception. Simulated small size (produced by side branch removal) in
A significant reduction in stalk dry weight was found to occur during the last half of grain‐filling period for several corn ( Zea mays L.) hybrids grown at various plant populations two seasons Ontario. This decrease attributed a remobilization towards ear soluble carbohydrates stored temporarily stalk.
Triazine‐resistant (TR) spring rapeseed (canola) ( Brussica napus L.) cultivars have been developed that permit selective chemical control of weeds but TR generally yield 20 to 30% less than triazine‐susceptible (TS) cultivars. This lower in has attributed impaired electron flow between photosystems I1 and I. The objective this experiment was use reciprocal TS hybrids assess the effects trait same nuclear genetic background. canola cv. OAC Triton handcrossed with two cv., Topas Hanna, create...
Individual soybean [ Glycine max (L.) Merr.] plants grown in the field during 2 years were allowed to assimilate 14 CO2 either vegetative growth, at first flowering, early pod development, or rapid seed development. Some of labeled harvested immediately after labelling, and others 1 week, incipient leaf drop, maturity. Radioactivity was measured component parts each labelled plant. Plant that growing actively time labelling accumulated more C than those not actively. When vegetatively, most...
Two experiments were conducted to identify soybean [ Glycine max (L.) Merrill] strains that nonsensitive photoperiod for possible use as parental lines in a breeding program. Twelve varieties subjected photoperiods of 12, 16, 20 and 24 hours growth cabinets. The number days from planting until first flower was increased by long all but 1 12 varieties. Early maturing less sensitive than later this reason, 111 Maturity Group 00 grown controlled‐environment room at 22, 23 hours. In...
In the absence of Bradyrhizobium japonicum populations in soil, yields field-grown soybean (Glycine max (L.) Merrill) usually respond to inoculation with B. japonicum. The objective this research was determine relationship between numbers per seed inoculants and nodulation yield. A total six field experiments were conducted 1989 1990 on new soils. dilution trials, Grip inoculant applied provide approximately 10 6 , 5 4 3 at two locations 1989. Nodule number mass, as well yield, increased...
Field trials were conducted at different sites close to Guelph, Ontario, from 1981 1985, evaluate the effects of Hup + and − strains on performance soybean (Glycine max L. Merrill) identify that could support high yields under Ontario conditions. Each year six individual strains, Nitragin Soil Implant granular inoculant an uninoculated control compared for their effect yield. each experimental site was relatively free indigenous B. japonicum as exhibited by average less than one nodule per...
Acetylene reduction estimates of N 2 fixation and nodulation by white bean (Phaseolus vulgaris) are generally low under field conditions. Recent reports using 15 dilution have resulted in higher estimates. In the work reported here, determined acetylene reduction, dilution, difference method were compared Difference assays also controlled environment Soybean (Glycine max), which has given high all three methods is well nodulated conditions, was included as a control. Results from experiments...
Nodule leghemoglobin content, acetylene reduction rates, and nodule weight determinations were made during an entire growth period of soybean (Glycine max (L.) Merr. cv. Altona) plants grown under field conditions. High correlations within most sampling dates found between each pair possible comparisons these indicators nitrogen fixation.Rates conversion to ethylene per milligram constantly decreased the growing season, whereas content gram fresh remained relatively constant. These results...
OAC Triton is the first licensed, triazine-resistant spring rapeseed (Brassica napus L.). It produces seed low in erucic acid and glucosinolate content. Yield levels have averaged approximately 80% of Regent oil content has 2.4% less than Regent. expected to be used where production restricted or inhibited by serious cruciferous weed infestations, other triazine-susceptible problems, atrazine herbicide residues.Key words: Rapeseed, triazine-resistant, Brassica L., canola, cultivar description
This review considers the main factors determining level of nitrogen fixation in major grain-legume crops (chickpea, common bean, cowpea, faba lentil, pea, peanut, pigeon pea and soybean) discusses possibilities means for improving symbiotic fixation. Methods whether is limiting growth yield are discussed, responses various to both addition fertilizer inoculation with effective strains rhizobia described.

White bean (Phaseolus vulgaris L.) is generally reported to fix less N than soybean (Glycine max Merrill [L.]). Recent work has shown that in the onset of physiological responses conserve plant and soil water occurs at greater deficits some other legumes. Little known about use regulation white bean. Research was conducted compare these two species deficit, particularly its effects on 2 fixation, both controlled environment field conditions. In growth room, potential, leaf diffusive...
Additional frost tolerance in soybeans ( Glycine max (L.) Merr.] would be a useful trait. Our research was conducted to test the effects of prefrost temperatures, stages plant development, and genotype on soybeans. In one experiment, 30 genotypes were tested for tolerance. Plants grown controlled environments at day/night temperatures 15/9, 20/14, 25/19 C, then subjected advective white frosts − 2, 2.5, 3 C. cotyledon, unifoliolate, or first trifoliolate leaf stage factorial design, total 27...
Soybeans (Glycine max (L.) Merrill), inoculated with 1.75 kg/ha of seed-applied inoculant (Rhizobium japonicum (Kirchner) Buchanan) or 40 granular, soil-applied inoculant, were grown in 1976 and 1977, along uninoculated control plots, fields planted to soybeans for the first time. Control plots averaged 2.1 t/ha, compared 2.6 t/ha 3.1 granular treatment. However, neither treatment increased yields over controls on land where had been before. In 1978, two commercial inoculants one treated at...
Soybeans (Glycine max (L.) Merrill) often do not give yield responses to added fertilizer nitrogen (N) because high soil N levels inhibit fixation of atmospheric 2 . Yield applied at planting usually indicate that is less than optimal. The effects inoculation with Rhizobium japonicum, and levels, on soybean (C H ) seed yields in Ontario were investigated ’ 1976 1977. Three locations used each year, representing areas where soybeans had been grown for many years (Ridgetown), only a few...
