Sorghum Leaf Area as a Function of Sixth Leaf Area

Journal of Agronomy and Crop Science, 1989
AbstractThis study was undertaken to determine the relationship between sixth leaf area and total leaf area of sorghum (Sorghum bicolor Moench) to obtain the total leaf area estimate without having to make the time consuming area measurement directly. Ten sorghum varieties were raised at Tamil Nadu Agricultural University campus Coimbatore from which ...

Leaf Area Index and Specific Leaf Area Determinations

Journal of Agronomic Education, 1972
ABSTRACTLeaf area is measured by several methods and area per unit leaf weight (specific leaf area) is calculated. Leaf area index is then calculated as the product of leaf yield and specific leaf area. Procedures and equipment needed are described.

The Time Value of Leaf Area

The American Naturalist, 2000
When a plant invests in construction of a leaf, the revenue-stream that accrues is shaped by three variables: first, the light-capture area per milligram dry mass invested, analogous to a potential rate of return on investment; second, the longevity of the leaf, analogous to the expected duration of the revenue stream; and third, a time-discount rate ...

Minimum areas and leaf determination

Proceedings of the Royal Society of London. Series B - Biological Sciences, 1952
Abstract In shoot apices of Lupinus albus the greater part of the presumptive area of I2, the leaf due to arise next but one, was confined between vertical radial cuts as nearly as possible 100° apart. No leaf was formed between the cuts except in apices near to flowering, in which the leaves are always much smaller.

A systems study of lotus's leaf area

Kybernetes, 2007
PurposeA systematic study of a lotus's leaf area is described through the genetic improvement of Lotus glaber, an induced tetraploid population known as, Leonel, was obtained. Initial assessment showed an increase in dry material in comparison with a diploid population.

Leaf Area and Absolute Leaf Water Content

Annals of Botany, 1970
Leaf area was found to be an almost linear function of absolute leaf water content (that is fresh weight- dry weight) for several dicotyledonous genotypes. A closely similar relationship held for a given genotype in the same rooting medium despite increasing plant size and different treatments which resulted in leaves which were sometimes ...

Leaf Area Index

2013
This chapter briefly introduces the inversion algorithms used, discusses the product characteristics and validation results, and presents preliminary analyses and applications. The inversion algorithm was developed to estimate LAI from time-series remote sensing data using general regression neural networks (GRNNs).
