Nitrogen reserves, spring regrowth and winter survival of field-grown alfalfa (Medicago sativa) defoliated in the autumn.
AIMS The objective of the study was to characterize variations in proline, arginine, histidine, vegetative storage proteins, and cold-inducible gene expression in overwintering roots of field-grown alfalfa, in response to autumn defoliation, and in relation to spring regrowth and winter survival. METHODS Field trials, established in 1996 in eastern Canada, consisted of two alfalfa cultivars (...
متن کاملSensitivity of cold acclimation to elevated autumn temperature in field-grown Pinus strobus seedlings
Climate change will increase autumn air temperature, while photoperiod decrease will remain unaffected. We assessed the effect of increased autumn air temperature on timing and development of cold acclimation and freezing resistance in Eastern white pine (EWP, Pinus strobus) under field conditions. For this purpose we simulated projected warmer temperatures for southern Ontario in a Temperature...
متن کاملBurnet of Australia.
'Darwin is the greatest of all scientists, greater even than Newton or Einstein, and I am quite certain that my own thinking has been more deeply influenced by the evolutionary concepts of Darwin than by anything else' (Burnet, 1966). 'Life must have begun as some particular configuration of atoms, an inconceivably tiny knot of molecular structure, which by some freak of circumstance was able t...
متن کاملCalibration and validation of a soil water simulation model (WaSim) for field grown Amaranthus cruentus
A water simulation model (WaSim) to simulate the growth and development of Amaranthus cruentus as well as the components of water balance for a typical sandy-clay-loam soil of Akure has been described. Dry season experiments were carried between January and March of 2005 and 2006. Amaranthus seeds were established on the field and three irrigation water managements were imposed on the crop to d...
متن کاملInteraction of different irrigation strategies and soil textures on the nitrogen uptake of field grown potatoes
Nitrogen (N) uptake (kg ha-1) of field-grown potatoes was measured in 4.32 m2 lysimeters that were filled with coarse sand, loamy sand, and sandy loam and subjected to full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation strategies. PRD and DI as water-saving irrigation treatments received 65% of FI after tuber bulking and lasted for six weeks until final harvest. Results show...
