Leaf Epidermal And Pollen Morphological Studies Of Genus Jatropha L. (Euphorbiaceae) In Nigeria

摘要

Abstract : The predominated plant genus of Jatropha were studied using the epidermal cell morphology and pollen morphology to express more reliable power to its identification aside from the normal flower and other features key arrangement, they all had paralytic stomata type with absence of stomata at the abaxial with no traces of trichomes, J. multifida is having the highest stomata length of 27.5'm with highest stomata with 17.5'm while J. curcas, J. podagrica and J. gossypifolia varies between 15.0 'm in stomata length to 12.5 'm in stomata width. They also have straight to curve anticlinal cell walls. They all possess large grain with exine pattern all croton while only J. multifida has the smallest gemmae size of 2.50 'm and its polar axis and equatorial diameter carries lower parameters of 52.1 'm and 51.6 'm respectively while it may be more affected by environmental factor and that is why the results is good but calls for more genetic expression.
