Abstract:
The expansion period tuber of white yam of Anping from Hebei was used as the experimental material, by using different concentrations of calcium, the yam tuber morphological indicators changes, the content of starch, amylase and starch synthase and the change of calcium ions, calmodulin content were neasured, the correlation analysis for these date under different concentrations of calcium was conducted，and the calcium ion and calmodulin physiological mechanism of the impact in the period of Chinese yam tuber bulking were explored.The results showed that the application of appropriate concentration of exogenous calcium (74 kg?hm-2) could promote the tuber swelling, starch synthesis and accumulation, increase the content of starch synthase, and promote the content of endogenous calcium ions and calmodulin in the tuber.Finally,the results of this experiment will serve as a reference for the study of the physiological mechanism of yam.
