The leaf index: heteroblasty, natural variation, and the genetic control of polar processes of leaf expansion.

Plant & cell physiology - 1 Apr 2002

Tsukaya Hirokazu

Abstract excerpt

The morphology of the leaves of angiosperms exhibits remarkable diversity. One of the factors showing the greatest variability is the leaf index, namely, the ratio of leaf length to leaf width. In some cases, different varieties of a single species or closely related species can be distinguished by differences in leaf index. To some extent, the leaf index reflects the morphological adaptation of leaves to a...
