申嗪霉素与氨基酸浸种对黄瓜和番茄种子萌发的影响

以黄瓜品种碧秋和番茄品种中杂9号为试材,研究不同浓度申嗪酵素(10、50、100、125、175 mg·L~(-1))、氨基酸母液(50、333、833、1 250、2 000 mg·L~(-1))及适宜浓度的复混液对黄瓜和番茄种子萌发及胚生长的影响。结果表明:适宜浓度的氨基酸母液和申嗪酵素能显著提高番茄、黄瓜种子的发芽势、发芽指数、活力指数,并显著促进胚根和下胚轴的生长。番茄种子萌发的最适浓度为氨基酸母液50 mg·L~(-1),申嗪酵素10 mg·L~(-1);黄瓜种子萌发的最适浓度为氨基酸母液333 mg·L~(-1),申嗪酵素50 mg·L~(-1);番茄和黄瓜种子胚根及下胚轴生长最适浓度均为氨基酸母液333 mg·L~(-1),申嗪酵素50 mg·L~(-1)。申嗪酵素对2种蔬菜种子萌发的促进效果优于氨基酸母液,对黄瓜的促根生长作用亦优于氨基酸母液,而氨基酸母液对番茄的促根生长作用较好。333 mg·L~(-1)氨基酸母液与50 mg·L~(-1)申嗪酵素的复混液(1 V∶1 V)对番茄和黄瓜种子萌发及胚根、下胚轴的生长具有一定的促进作用,但不如两种物质单独使用效果好。

Effect of Soaking Seed in Shenqinmycine and Amino Acid Liquid on Seed Germination of Tomato and Cucumber

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．
