Abstract:
Effects of potassium concentration in the soil on the morphological and physiological characteris-tics of soybean root were studied by taking soybean varieties sensitive differently to potassium as materialsin potted experiment. Results showed that for the variety Tiefeng 31 insensitive to potassium , its rootcharacteristics such as lateral root length , root dry weight , root active absorbing area and root activity were not affected obviously by the decreasing of potassium concentration ;but for the varietyTie 95068 - 5 sensitive to potassium , just the reverse was true. Under the condition of low potassium con-centration, the expressions of root characteristics in Tiefeng 31 were beneficial to forming high yield. SoTiefeng 31 can be used as parent in breeding program for varieties tolerant to low potassium level or direct-ly planted as available variety in the soil with low potassium concentration.
