microspore culture was applied to induce embryogenesis in roses (rosa hybrida) cv. hav1. important factors affecting viability of isolated microspores and formation of multi-cellular structures including isolation media (nln, ab, b) and induction media were studied. the most responsive developmental stage of microspores (late unicellular) was determined using dapi staining. the least infection ...

A bstract We formulate a strategy for computing the complete set of non-perturbative corrections to closed string scattering in c = 1 theory from worldsheet perspective. This requires taking into account effect multiple ZZ-instantons, including higher instantons constructed ZZ boundary conditions type ( m, 1), with careful treatment measure and contour integration over instanton moduli space.
