Some luminescence characteristics of allocytoplasmic wheat hybrids

Comparative studies of thermoluminescence and slow fluorescence induction w ere carried out on leaves of allocytoplasmic hybrids and standard regionali zed wheat (cultivar Zarya). There are differences in luminescence indices b etween these objects correlated to the thermoluminescence and slow fluoresc ence induction methods. These differences allow estimation of the functiona l activity of the photosynthetic system. All studied allocytoplasmic hybrid s exceeded the standard wheat in both luminescence indices F-M/F-T(slow flu orescence induction) and S-A/S-tot (thermoluminescence) and productivity (h eight of seedlings, number of ears and grains, grain mass, etc.). The highe st values of F-M/F-T and S-A/S-tot and the lowest value of S-C/S-tot were r ecorded in the allocytoplasmic hybrid Igen 3 x Mironovskaya 808, which is c haracterized by the highest productivity.
