Wind and Sandblast Injury to Seedling Green Beans1
- E. L. Skidmore2
Seedling green beans were subjected to various combinations of windspeed (20, 30, and 40 mph), abrasive flux (0, 0.2, 0.4, and 0.6 ton per rod width per hour of sand), and duration of exposure (5, 10, and 15 minutes) in a wind tunnel. Wind alone with speeds up to 40 mph caused only slight damage, Introduction of as little as 0.2 ton per rod width per hour of sand into the windstream greatly increased plant injury. However, additional increases in abrasive flux causesd no proportionate increase in plant injury. Plant damage increased linearly and bean yields decreased almost linearly with increase in windspeed and duration of exposure. Although the plants abraded at 20 mph sustained injury, they recovered sufficiently to yield well. The yield of plants abraded at 30 and 40 mph decreased with increased sand flux.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
