Regrowth of Alfalfa After Heat Stress
1974
Pulgar, Claudio E. | Laude, Horton M.
The extent and persistence of growth depression in alfalfa (Medicago sativa L.) following heat stress was established under controlled conditions by comparing stressed with unstressed plants of the same clone. Temperatures were used that simulated the periodic heat extremes of the field. Significant reduction in number and length of shoots in the regrowth was obtained within 7 days of stress. The period of depressed growth was extended as the intensity of stress was increased either by elevating temperature or lengthening exposure tune. Measurable reduction in shoot numbers and size persisted up to 6 weeks following a stress which produced no visible evidence of tissue mortality.
