Publication number: 20240130362Abstract: A composite solution for enhancing induced disease resistance of lentinan (LNT) to a plant, a preparation method of the composite solution, and a method for enhancing induced disease resistance of LNT to a plant are provided. The composite solution for enhancing induced disease resistance of LNT to a plant includes: an LNT-containing solution and an SPc-containing solution, where SPc is a dendritic macromolecule functionalized by an amino functional group, and has a structural formula shown in formula I, where n=1 to 100. An LNT/SPc complex is produced in the composite solution. SPc spontaneously combines with LNT through hydrogen bonding, such that an agglomerate structure formed by LNT in an aqueous solution is broken and reduced to a nano-scale particle size, and a spherical particle is produced, which can significantly reduce a contact angle of the LNT aqueous solution, and promote the distribution and diffusion of LNT.Type: ApplicationFiled: August 15, 2023Publication date: April 25, 2024Applicants: KUNMING CO YUNNAN TOBACCO CO, China Agricultural UniversityInventors: Yonghui XIE, Dekai NING, Zhijiang WANG, Shuo YAN, Wei LI, Jie SHEN, Zhengling LIU, Qinhong JIANG, Youguo ZHAN, Yuanshen WANG, Cun GUO, Sihao WU, Haohao LI
