Evaluation of Reserve Carbohydrates in Midland Bermudagrass (Cynodon dactylon L.)1
- J. S. Burris,

- R. E. Blaser2
Midland bermudagrass was grown at 35 and 30 C day and night temperatures with 300 and 30 pounds of nitrogen. The rhizomes were harvested at 7-day intervals and reserve carbohydrates determined by 0.2 N H2SO4, 2% H~SO4, taka-diasl:ase, alpha-amylase, and perchloric acid extractions
The glucose extracted by either acid or taka-diastase was compared with starch extracted by alpha-amylase. It was found that at the 5% level the glucose extracted by 0.2 N H2SO4 and taka-diastase was the same as the starch; while the 2% H2SO4 was higher. This correlation may not be applicable to other studies or other plant materials where weak structural materials may contribute glucose to the acid extractions.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
