Abstract
Leaf shape simulation of castor bean and its application in nondestructive leaf area estimation
Highlights
The leaf is an important organ of plants
Montgomery[4] put forward a leaf area formula for corn: the leaf area (A) = k × leaf length (L) × leaf width (W)
Where k is a constant to be fitted; The leaf length is defined as the distance from leaf apex to leaf base; The leaf width is defined as the maximum length of the segments perpendicular to the straight line passing through leaf apex and leaf base[5]
Summary
The leaf is an important organ of plants. Plant leaves participate in many physiological processes, such as transpiration, photosynthesis and so on. The leaf area is an important determinant of light interception and of transpiration, photosynthesis and plant productivity[1]. The Montgomery model has been demonstrated to be appropriate for calculating leaf area for other herbaceous and woody plants such as cotton, rice and sorghum[6,7,8]. These models would have many advantages, such as an expression in dimensional terms of length and width of a leaf, which would be easy to measure many plants with simple shape leaf, but not to easy measure other plants with complex shape leaf, such as caster bean leaf
