Email this article A Method for Determining Leaf Area of One, Two and Three Year Old Coconut Seedlings (Var. CRIC 60)
Abstract
A rapid, non-destructive and accurate method for determining the leaf area of
one, two and three year old coconut seedlings (var. CRIC 60) is proposed using three
linear regression models y = 5.9647 + 0.6314 x, y = 3.9325 + 0.7044* and y =
8.4507 + 0.6798* with reliabilities of 94.5%, 98.3% and 97.8% respectively, where x
is the product of the length and breadth at the broadest position of the leaflet and y
is the area of the leaflet. In order to study the relative performance of seedlings, a
common model y = 2.2138 + 0.7192 x ( r 2 = 98.6%), which can be considered to be
representative, could be used irrespective of the age of the seedling, if the third leaf
is used.
