which was applied at the middle and late stages of hybrid rice Shanyou 63
could raise the contents of total chlorophyll and soluble protein
could increase superoxide dismutase(SOD)activity and could decrease the content of malondialdehyde(MDA) which is a product of membrane lipid peroxidation in flag leaves. In addition
Ca could also increase the effective panicle of plant

1 000 grain weight and grain yield. It was preferable to apply 2 g CaCl 2 per pot than l g CaCl 2 per pot for ten days before heading and to apply the same amount of CaCl 2 in once than twice.
