Description

From the results of the above experiments we can summarize the following differences in chemical properties between the pith and cortex of “sote-tsu”-plant.<br> (1) The starch content of the pith is greater than that of the cortex but in the case of male pant shows a reversed tendency.<br> (2) The amount of reducing sugar of the pith is less than that of the cortex. On the other hand, the non-reducing sugar content of the pith is always superior to that of the cortex.<br> (3) The crude fat and fibre contents of the pith are always inferior to those of the cortex.<br> (4) A very significant difference of the peroxidase action was observed between the pith- and cortex-juice; that is, in the juice of cortex, the enzyme action is more active than that of the pith.<br> Concerning the sex differences on the chemical properties of “sotetsu”-plant, we can summarize as follows:<br> (5) Difference of the quantity of starch between the male and female (A and B) plants were determined. In those results, there is nothing to choose between the two stems of male and female B; then in the female A, considerably small amount of starch than those of the male and female B, was estimated. This phenomena shows that the starch was consumed newly, in order to bear the seed.<br> (6) The dextrin content of the female B is very large than those of other stems.<br> (7) The content of reducing sugar of the female A was considerably greater than those of other stems. The same tendency was observed in the amount of non-reducing sugar.<br> (8) The protein and ash contents of the female stems in both A and B are always greater than those of male stem.<br> (9) The peroxidase action of the juice of female stem B is almost equal to that of male stem, but the enzyme action of female stem A is poor.
