氨基酸喷施和种子包衣对玉米幼苗生长及抗冷性的影响
Effects of Amino Acid Spraying and Seed Coating on Growth and Cold-tolerance of Maize Seedlings
摘要
Abstract
[Objection]In order to investigate the effect of amino acid spraying and seed coating on the growth and development of maize seedlings and their cold tolerance,[Methods]the maize seeds were coated with Metalaxyl-M·Fludioxonil FSC,and seedlings were cultured to 3 fully expanded leaves and then transplanted to an artificial climate chamber for cultivation.Three treatments were set up at normal and low temperature,respectively:control,amino acid treatment,and amino acid and seed coat synergistic treatment.[Results]The results showed that the treatments of amino acid spraying and amino acid spraying+seed coat synergistic application effectively alleviated the inhibition of low temperature on the height and stalk thickness of maize seedlings and significantly promoted the growth of seedlings.They also significantly increased SPAD values,photosynthetic capacity,peroxidase activity and soluble sugar content of maize seedlings,effectively reducing the damage to cells by low temperature.Among these,the synergistic application of amino acid spraying+seed coat showed superior effectiveness.[Conclusion]Seed coating and foliar spraying of amino acids can effectively alleviate low temperature stress and improve cold tolerance in maize seedlings.关键词
