METHOD FOR PERENNIALLY MASS-PROPAGATING THE USEFUL ANNUAL PLANTS BY USE OF THE SHOOT PRIMORDIA

摘要

Abstract of the DisclosureA method for perennially mass-propagating auseful annual plant by use of shoot primordium, comprisescutting off a shoot apex from the useful annual plantand transplanting the thus cut off shoot apex into anartificial culture medium containing an inorganic saltcomposition and a plant growth hormone; rotation-culturing the shoot apex under the conditions that atemperature is 15-30°C, an illumination intensity is2,000-9,000 luxes and a number of revolution is0.5-10 rpm to propagate the shoot primordium; andstationally culturing the shoot primordium to formyoung plants. The useful annual plant can be perenniallymass-propagated in a short period of time while maintain-ing the genotype and chromosomal type for a number ofyears. This method is particularly effective withrespect to the propagation of triploid water melon,hybrid vigor Indian corn, hybrid vigor rice plant, andhybrid morning glory.
