Abstract:
Taking Festuca elata’Liegou NO.5’seeds as the test materials,the effect of different concentration of external source zinc on Festuca elata seed germinating capacity,germinating energy,the protein contents,the reducing sugar and total sugar contents and the amylase activity were studied.The results showed that Zn inhibited Festuca elata’s seed germination,reduced the germinating energy.Different concentration of Zn had a certain promoting effect on the amylase activity and the soluble sugar contents,but lowered the α-amylase activity and the contents of soluble protein and reducing sugar at the initial stage of Festuca elata seed germination.
