Abstract It is well-known that the number of particles produced in cosmology, commonly defined in the literature from the Fock space of the instantaneous hamiltonian of the canonically normalized fields, is ambiguous.On the other hand, the energy computed from the energy-momentum tensor Collections should be physical.We compare the corresponding Fo

In this Collections paper the influence of factors affecting gynogenic response of red beet ovules is discussed.The ovule response frequencies were the highest in the following conditions: N6 (Chu 1975) mineral salts, 0.5 mg/l IAA, 0.2 mg/l BA, 27 or 32oC.The influence of genotype of donor plants was confirmed and it was found that the ovules excis
