Method for reducing morbidity of first-generation tissue culture seedlings of wilt-resistant banana variety

The invention provides a method for reducing wilt morbidity of first-generation tissue culture seedlings of a wilt-resistant banana variety, and belongs to the technical field of plant disease control. The disease incidence rate of fusarium wilt of banana is lower than 8% by performing stem cutting on first-generation tissue culture seedlings of anti-wilt banana plants, putting a compound fertilizer into the core parts of cut stems to promote the cut stems to generate offsets n, and reserving 1-2 robust offsets, the incidence rate of wilt of the first-generation tissue culture seedlings of theanti-wilt banana variety is greatly reduced. 本发明提供了一种降低抗枯萎病香蕉品种一代组培苗枯萎病发病率的方法，属于植物病害防治技术领域。通过对抗枯萎病香蕉植株一代组培苗进行截茎，在截茎芯部投放复合肥，促使其产生吸芽，留取1～2株健壮吸芽的处理，使得香蕉枯萎病的病发率低于8％，大大降低了抗枯萎病香蕉品种一代组培苗枯萎病的发病率。
