Seedling morphology of Nicotiana plumbaginifolia Viv. and N. rustica L. (Solanaceae).

Abstract

The seedling morphology of two exotic taxa Nicotiana plumbaginifolia Viv. and N. rustica L. of the family Solanaceae have been observed upto 5th true leaf stage. Some seedling attributes viz. collet, colour of hypocotyl, shape, base, apex and venation of seed leaves and their persistence and shape; apex and venation of true leaves have been found useful in distinguishing the taxa studied. This has been supported by the construction of an artificial key and illustration. RS values are also recorded.
