Abstract
To investigate the growth efficiency of harvesting organs of rice, winter wheat, oat, barley, maize, sorghum, soybean, field bean, lupin, pea, adzuki bean, chick pea, peanut, sunflower, safflower, flax, rape, castor bean, cotton, and potato, the dry weight and respiratory rate of the harvesting organs were measured and the composition of crude chemical components was determined during maturation. Thus, as there was no clear relationship between the composition of the chemical components and the growth efficiency among the crops, it was difficult to estimate the conversion efficiencies for the production of each chemical component using a unit of glucose based on the experimental data. It is, therefore, suggested that reassimilation of respired CO2 or photosynthesis should be included to estimate the carbon balance in the harvesting organs.
