Estimating leaf area in mango (Manguifera indica L.) and avocado (Persea spp) seedlings at the nursery stage by using its lineal leaf measurements
Main Article Content
Abstract
leaf area, which are classified as destructive, non-destructive
and estimating ones. This work was aimed at establishing a
non-destructive approach for estimating leaf area in mango
(Manguifera indica L.) and avocado (Persea spp) seedlings
by using its leaf lineal measurements. It was conducted in
nurseries devoted to fruit seedling production and marketing.
Mango and avocado plants were sampled 120 days after being
transplanted (ddt) to bags containing substrates combined
by different sources, since it was considered the right time to
record leaf surface. Regression analyses were performed by
applying Y= a+b*X lineal pattern besides using Statgraphics
5.1 plus for Windows program, selecting just highly adjusted
equations. For both fruits, moderately strong relationships
were achieved between the analyzed variables, standing out
leaf area correlations with the product of leaf length by its
width, it being statistically significant for a value of P?0.01**.
