 en Morphological Characters, Occurrence and Distribution among Members of the Family Solanaceae in Parts of the Niger Delta Ecological Zone
WAHUA, C. & EDWIN-WOSU, N.L.

Abstract

This study investigated a comparative micro-morphological features of 14 species in the family Solanaceae, using trichome and stomatal complements in delimitation of species and genera within the taxon, family. The genus Solanum check for this species in other resources L. is the largest among the genera in Solanaceae. Solanum aethiopicum check for this species in other resources Linn. Solanum macrocarpon check for this species in other resources Linn. Solanum torvum check for this species in other resources Swartz. Solanum anomalum check for this species in other resources Thonn. Solanum erianthum check for this species in other resources D. Don, are covered with stellate trichomes. While Solanum nigrum check for this species in other resources Linn., Solanum lycopersicum check for this species in other resources Linn., Solanum incanum check for this species in other resources Linn., Datura check for this species in other resources spp., Schwenckia check for this species in other resources spp., Capsicum check for this species in other resources spp., Physalis check for this species in other resources spp. have simple uniseriate trichomes. S. aethiopicum Linn. S. torvum Swartz. S. lycopersicum Linn, and Physalis micrantha check for this species in other resources Linn, revealed higher trichome indices. In most species, these trichomes are not visibly observed with the naked eyes. While in some others such as in S. torvum and S. lycopersicum the trichomes are observable on the plants. Glandular hairs are also present in Solanaceae. Stomata is amphistomatic, types commonly observed are: anisocytic and anomocytic, while paracytic and tetracytic stomata are sometimes revealed in stem epidermis in Solanaceae. The usefulness of trichome and stomatal complements in species and generic taxa are recommended as pertinent characters for classification in Solanaceae and their density may vary from one ecological zone to another.© JASEM
