Embodiment Construction

[0008] The dry seeds sent by Xiaba Huamuchang, Dutou Village, Baijia Township, Liuyang City, Hunan Province, are first soaked in warm water at about 50°C for 24 hours, and then boiled for 1 hour to completely soften the outer and middle seed coats, and then put them in the binocular Under the dissecting microscope, peel off the outer testa and middle seed coat with a scalpel from the micropylar end. After the seeds are dry, place the seeds in a 70% ethanol solution by volume and oscillate with ultrasonic waves for 1 hour, and clean the chalazal area with a brush and a dissecting needle. The cleaned seeds were sprayed with gold film by ion sputtering, and the morphological characteristics of the chalazal area of ​​the endocarp were observed and photographed under a JSM-T300 scanning electron microscope. Then it was identified as Ledong Pseudomonas magnolia according to its features of curved chalazal tube, smooth inner testa surface and no seed ridge indentation.
