| Abstract: | Soaking sweet sorghum seeds in Ca2+,Zn2+ and their mixturecan improve the growth of the seedling, the length of the root, the number of roots and the height of seedling. It can also raise theactivities of amylase and invert sugar during the process of seeds prouting, enhance the respiratory rate, improve to sprout and heightenthe rate of emergence. And it can ijncrease the activity of SOD, PODand CAT, and strengthen the seedling drough resistance. |
