Leaf area estimation in triticale by leaf dimensions

Leaf area estimation by a simple and non-destructive method

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

Convergence in leaf size versus twig leaf area scaling: do plants optimize leaf area partitioning?

BACKGROUND AND AIMS Corner's rule states that thicker twigs bear larger leaves. The exact nature of this relationship and why it should occur has been the subject of numerous studies. It is obvious that thicker twigs should support greater total leaf area ([Formula: see text]) for hydraulical and mechanical reasons. But it is not obvious why mean leaf size ([Formula: see text]) should scale pos...

Transmission error in the photometric estimation of leaf area.

A numnber of authors have recommended the use of photometric apparatus for determining leaf area, and at least 1 commercially-manufactured instrument is available. In principle the leaf is placed between a light source and a photocell or battery of photocells: the reduction in photocell output due to the presence of the leaf then gives a measure of leaf area. The transmission of light through t...
