A Prototype Sensor for Estimating Light Interception by Plants in a Greenhouse [PDF]
, 2008 Light interception is one of the most important factors for plant growth. The intercepted amount depends on the incoming radiation in the greenhouse and the percentage of interception by the crop and is directly related to the leaf area.

Conversion of total leaf area to projected leaf area in lodgepole pine and Douglas-fir [PDF]
Tree Physiology, 1998 Three definitions of leaf area index (LAI) in the literature have no predictable relationship with each other. Factors were derived for converting total LAI to projected LAI of horizontal leaves and to projected LAI for inclined leaves of lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) and coastal Douglas-fir (Pseudotsuga menziesii (Mirb.)

Leaf Area Estimation in Chamomile
Journal of Agricultural Science, 2019 The knowledge of the variables specific leaf area and leaf area index is important for direct or indirect quantification of plant growth, development and yield. However, there is a lack of these information due to the difficulty in measuring the leaf area of chamomile.

Another dimension from LiDAR – Obtaining foliage density from full waveform data [PDF]
, 2011 LiDAR tells the user where surfaces are, not what they are. In this study we investigate the potential for waveform LiDAR to provide more information on the nature of the returns over forestry. Waveform LiDAR was acquired for ten Pinus radiata plots in a

A linear model for leaf area measurement to screen potential leaf material for herbal drug in Adhatoda vasica L. [PDF]
, 2016 Leaf area is an important parameter in physiology and agronomy studies. Linear models for leaf area measurement are developed for plant species as a nondestructive method. The plant Adhatoda vasica L.
