Whether buds in leaf axils resume growth to produce side branches (e.g., in dicots) or tillers in grasses depends on genotype and environment. The potential for axillary branches is always present, since there is a bud in each leaf axil. Modern maize hybrids do not tiller, except for the development of ear shoots, despite favorable […]

Article shared by :
In this article we will discuss about:- 1. Initiation and Emergence of Leaves 2. Number of Leaves Produced on a Shoot 3. Senescence 4. Factors Affecting Growth. Initiation and Emergence of Leaves: Leaf initials (primordia) begin with certain cells in the apical dome, which divide (become meristematic) and produce swellings or protuberances on the stem […]
Stem: Internode Elongation and Growth | Botany
Article shared by :
The stem consists of internodes spaced between the nodes, with attached leaves. The number of nodes and internodes is equal to the leaf number, all three having a common origin in the phytomer. Shoots of temperate grasses have compacted or untelescoped nodes (without internode elongation), which, until elongation after floral initiation are positioned below the […]
