Abstract
Nucellus cultures of Luffa cylindrica and Trichosanthes anguina (Cucurbitaceae) have been established. Tracheary differentiation occurred in cultures of both taxa. Supplementing the culture medium with 2,4-D caused limited and diffuse differentiation of tracheary elements. In the absence of 2,4-D, tracheary differentiation was profuse and the tracheary elements formed compact nodules; the differentiation of tracheary nodules could be traced to well-developed meristemoids. Our results show that the formation of tracheary nodules is an ultimate event in morphogenesis and bears no causal relation to organogenesis. The suitability of the nucellus as a system for studies on tracheary differentiation is emphasized.
