LIMBELLA FRYEI (WILLIAMS) OCHYRA DISTINCT FROM L. TRICOSTATA (SULL.) C.M. (MUSCI: AMBLYSTEGIACEAE)

抄録

  Investigation of branching patterns, morphology, karyotype, isozymes and shoot growth confirmed specific differences between Limbella tricostata (Sull.) C. M. and L. fryei (Williams) Ochyra. Significant differences were observed in branch bud frequency, leaf insertion angle, leaf areolation, chromosome length, electrophoretic mobility of superoxide dismutase, and shoot regeneration. Chromosome numbers of both taxa are n = 11. A key and descriptions segregate the taxa.
