In this article we will discuss about the anatomy of gnetum with the help of a suitable diagram. The root of Gnetum has diarch xylem, the endodermis bounds the multi-layered pericycle. The cortex of parenchymatous cells is filled with starch; the thick-walled fibres are also common in cortex. Tracheids have uni-seriate, bordered pits with conspicuous […]

In this article we will discuss about the process of reproduction in gnetum with the help of diagrams. Gnetum is dioecious, the fructifications are axillary (Fig. 18.1 A). The cones are lax to compact strobili. Microsporangiate fructification (Fig. 18.2A) has short internodes and number of reduced and modified bracts which form a complete cup or […]

In this article we will discuss about the morphology of gnetum with the help of a suitable diagram. In its morphology, Gnetum (Fig. 18.1 A) is closer in similarity to an angiosperm (dicot) than a gymnosperm. G. ula is a woody climber. It exhibits two types of branches, of limited growth (short shoots) and unlimited […]
