Type of article: Article

Summary

RESPIRATION OF SWEET POTATO ROOTS WAS SIGNIFICANTLY DEPRESSED BY LOW OXYGEN CONCENTRATIONS FROM 5 TO 15% COMPARED TO 20% O2, BUT RESPIRATION AT 2.5% O2 WAS HIGH. TOTAL SUGAR ACCUMULATED WITH LOW OXYGEN (2.5 AND 5.0%) STORAGE. PROTOPECTIN WAS LOW IN ROOTS STORED AT LOW O2 CONCENTRATIONS BUT WATER SOLUBLE PECTIN WAS NOT SIGNIFICANTLY AFFECTED. PHYSICAL PARAMETERS WORK AND MAXIMUM STRESS OF THE STORAGE ROOTS WERE HIGH WHEN STORED AT LOW O2 CONCENTRATIONS. MODULUS OF ELASTICITY AT YIELD AND FAILURE VALUE WERE NOT SIGNIFICANTLY AFFECTED. WORK WAS CORRELATED WITH TOTAL SUGAR (R R0.79-).
