✦ Synopsis

The karyotype of Nicotiana plumbaginifotia (2n = 20) was determined by the analysis of 25 metaphase plates of both haploid and diploid plantlets. The material originated from root tip meristems and leaf protoplasts. Chromosome length ranged from 1.73 to 4.34/am and the total length of the genome was 30.2 /sm. The following chromosome pairs have been recognized: three metacentrics, two submetacentrics, one subtelocentric, one subtelocentric with satellites and three telocentrics.

Factors affecting the regeneration of shoots from Nicotiana plumbaginifolia colonies were studied. As opposed to results obtained with tobacco, phytohormone pretreatments of those colonies did not appreciably affect their subsequent aptitude to develop shoots. Hexoses generally inhibited shoot morph
