Root growth of two drought tolerance and two drought sensitive bean (Phaseolus vulgaris L.) lines was compared at two locations in Colombia differing primarily in soil conditions. At Palmira, root of drought tolerant lineas reached a depth of 1.3m, while drought sensitive lines only reached 0.8m. These differences were associated with differences in seed yield, crop growth, canopy temperature and soil moisture extraction. Under acid soil conditions at Quiliacho, seed yields of supposedly drouught tolerant genotypes were similar to those of the drought sensitive lines, and root growth of all four lines was restricted to less than 0.8m. Drought avoidance through greater root growth and extraction of soil moisture appears to be an important drought tolerancemechanism in comon beans, but its usefulness is limited where soil conditions restrict root growth. |
