A liquid crystal image display comprising differential amplifiers composed of polycrystalline Si TFTs incorporated in buffer for a signal line driver. The front wheel is greater in rigidity than the rear wheel. Inside the bushing, between the pin and one internal side wall of the bushing, there are housed, alongside one another, at a pre-set axial distance apart from one another, one or more deformable annular gasket elements. The core 42 is mounted on the bobbin 2. Accordingly there is provided a method for preparation of a plant comprising in successive order establishing at least one plant parasite on at least one branch of a host plant, cutting at least one branch with at least one established plant parasite, and rooting the at least one cut branch.
