Abstract:
     A method for reduplicating the pollen chromosomes of eucommia tree by inducing features that a high-temp reduplicating device of tree is used to heat the male flower buds of eucommia tree in the meiophase of pollen metrocytes at 45-47 deg.C for 2 hr to increase the 2n pollen percentage to 45-70%, especially in the diakinasis-metaphase I.
