Abstract
A method of shoot-tip grafting in vitro has been developed to obtain virus-free peach plants.
It consists of aseptically grafting a 0.5 – 1.0 mm long shoot tip excised from a diseased plant on a 10-to-14-day-old Nemaguard seedling grown in vitro.
Shoot tips were composed of the apical meristem and three to four leaf primordia.
Between 45 and 70% of successful grafts were obtained and 60 to 70 % of the micrografted plants survived transplanting to soil.
By this method peach plants free of several strains of prunus ringspot virus, prune dwarf virus and chlorotic leaf spot virus were obtained.
