Taking cucumber‘Biqiu’and tomato‘Zhongza No.9’as experimental materia，this paper
studied the effect of different concentrations of shenqinmycin（10，50，100，125，175 mg·L^-1），amino acid
liquid（50，333，833，1 250，2 000 mg·L^-1） and mixed liquid with suitable concentration on cucumber and
tomato seed germination and embryo growth．The results showed that the amino acid liquid and shenqinmycin
with suitable concentration could significantly improve the germination potential，germination index，vigor
index of tomato and cucumber seeds， and promote significantly the growth of radicle and hypocotyl．The optimal
concentration for tomato seed germination was 50 mg·L^-1 amino acid liquid，10 mg·L^-1 shenqinmycin．
The optimal concentration for cucumber seed germination was 333 mg·L^-1 amino acid liquid，50 mg·L^-1
shenqinmycin．The optimal concentration for tomato and cucumber growth of radicle and hypocotyl were 333
mg·L^-1 amino acid liquid and 50 mg·L^-1 shenqinmycin．Shenqinmycin has better effect on promoting seed
germination of these 2 vegetable varieties than amino acid liquid．Furthermore，its promoting effect on root
growth of cucumber was superior than that of amino acid liquid．While，amino acid liquid had a better effect on
stimulating tomato root growth．
