Genom and Polyploidy in the Genus Trillium. IV

Abstract

The constant patterns of differentiation of specific chromosome segments, by the cold treatments, were established between chromosome pairs in the same cell, different cells of an individual, and in different individuals with the same type of chromosome. Since the patterns are characteristic for each set of chromosomes, constitutional genoms combined in polyploid spp. were identified with those genoms in diploid or other polyploid spp. The evolutionary sequence in the genus is detd. as: T. kamtschaticum Pallas (2x = 10, K1K1), T. Hagae Miyabe et Tatewaki (3x = 15, K1K2T), T. Hagae Miyabe et Tatewaki (6x = 30, K1K1K2K2TT), T. Tschomoskii Maximowicz (4 x = 20, K2K2TT), T. Smallii. Maximowicz (4x = 20, SSUU). T. amabile Miyabe et Tabewaki (6x = 30, K2K2SSUU).
