Article
Full-text available
Winter climate change including frequent freeze-thaw episodes and shallow snow cover will have major impacts on the spring regrowth of perennial crops. Non-bloating perennial forage legume species including sainfoin, birdsfoot trefoil, red clover, and alsike clover have been bred for their adaptation to harsh winter conditions. In parallel, the sel...
Article
High concentration of nonstructural carbohydrates (NSC) in forages improves ruminant N utilization and performance. The present study evaluated the direct and indirect effects of one cycle of divergent phenotypic selection for NSC in alfalfa along with the diurnal and seasonal stability of the trait. For this purpose, divergent NSC populations were...

Alfalfa and its rhizobial symbiont are sensitive to salinity. We compared the physiological responses of alfalfa populations inoculated with a salt-tolerant rhizobium strain, exposed to five NaCl concentrations (0, 20, 40, 80, or 160 mM NaCl). Two initial cultivars, Halo (H-TS0) and Bridgeview (B-TS0), and two populations obtained after three cycle...

Low freezing tolerance reduces the persistence of red clover under northern climate. The incidence of winter damages in perennial crops could increase in the future due to the adverse effects of the predicted warmer fall temperature on plant cold acclimation. To accelerate breeding progress, two cultivars of red clover Christie (C-TF0) and Endure (...
Article
Cold acclimation proceeds sequentially in response to decreases in photoperiod and temperature. This study aimed at assessing the impact of photoperiod prior to cold acclimation on freezing tolerance and related biochemical and molecular responses in two alfalfa cultivars. The fall dormant cultivar Evolution and semi-dormant cultivar 6010 were grow...
Article
Soil quality decline is a common concern in potato production systems. Including cereals and green manures (GMs) in potato rotation could improve soil productivity and sustain potato (Solanum tuberosum L.) yields and quality. This experiment initiated in Québec, eastern Canada, assessed the effects of two cycles of 2-yr potato rotations with cereal...
Article
Specific amino acids have protective functions in plants under stress conditions. This study assessed the effects of rhizobial strains on the amino acid composition in alfalfa under salt stress. Two alfalfa cultivars (Medicago sativa L. cv Apica and salt-tolerant cv Halo) in association with two Sinorhizobium meliloti strains with contrasting growt...
Article
Full-text available
The data provide an overview of proteomic changes in red clover (_Trifolium pratense_ L.) in response to cold acclimation and recurrent selection for superior freezing tolerance. Proteins were extracted from crowns of two red clover cultivars grown under non-acclimated or cold-acclimated conditions, and plants obtained from the initial genetic back...
Article
Full-text available
Improvement of freezing tolerance of red clover (Trifolium pratense L.) would increase its persistence under cold climate. In this study, we assessed the freezing tolerance and compared the proteome composition of non-acclimated and cold-acclimated plants of two initial cultivars of red clover: Endure (E-TF0) and Christie (C-TF0) and of populations...

Legume crops leave N‐rich residues and improve soil properties that can boost the yield of subsequent crops. This study conducted at two sites in Québec, eastern Canada, identified the most appropriate preceding legume crops for subsequent corn (Zea mays L.) and wheat (Triticum aestivum L.) yield and N nutrition. Legumes were established in 2011, i...

Available at: http://dx.doi.org/10.1016/j.apsoil.2014.11.08 Salt stress can affect alfalfa growth directly by adversely affecting metabolism, or indirectly by its effect on Rhizobium capacity for symbiotic N2 fixation. Growth and carbohydrate metabolism in leaves, roots and nodules of two alfalfa cultivars (Medicago sativa cv Apica and salt-toleran...

Bradyrhizobium (B), Azospirillum (A) and arbuscular mycorrhizal fungi (M) are plant beneficial rhizospheric microorganisms often applied as biofertilizers. The objectives of the present work were to study the effects of double (B + A and B + M) and triple (B + A + M) microbial combinations on soybean yield (Glycine max [L.] Merr.), nodulation, myco...
Article
The aim of this study was to evaluate the effects of fresh and composted paper sludge on macroaggregate stability of a silt loam under field conditions, and to assess the possible role of carbohydrate fractions and humic substances. The treatments included fresh paper mill sludge (PMS) and its compost (CPMS) applied at a rate of 40 Mg ha-1 with or...
Article
Soil aggregation is influenced by physical and chemical properties of organic materials applied to the soil. The objective of this study was to evaluate the effects of fresh paper mill sludges and their composts, and their application frequency on soil aggregation, mean weight diameter of aggregates (MWD) and on the C content and C mineralization f...
