Abstract:

It was studied the leaf and petiole tissue culture induction and plant regeneration with the sweet potato variety ‘Wanshu No. 7’. The result indicated the sweet potato variety of leave and petiole could be easy to induce callus in 7 induction mediums, the induction rate of 100%. The leaf and petiole induced green callus in the medium of MS +2.0 mg/L KT +0.5 mg/L IAA, and then subculture 15 days in the medium of MS +4.0 mg/L 6-BA + 0.01 mg/L NAA , they were induced emergence seeding.
