Con el objetivo de estimar la proporcion de luz que recibe cada cuadrante se calculo el porcentaje de PPFD horizontal a 1 m de altura con un sensor LI-190SA conectado a una datalogger LI-1000 (LI-COR, Lincoln, EUA), colocado en un lugar completamente expuesto y programado para medir el PPFD cada minuto y con otro sensor similar conectado a otro datalogger, con el que se registro el PPFD en cada cuadrante en la manana de un dia nublado (B.
To measure the basal rate of isoprenoid emissions, all gas exchange measurements were made in ambient [CO2] (380 M M-1), at PPFD (photosynthetic photon flux density) of 1000 uM m-2 s-1, relative humidity of 50-55% and leaf temperature of 30C.
Efectivamente, las hojas de las plantas cultivadas bajo mayor PPFD (0-40% sombra) fueron de menor tamano, pero esta respuesta se obtuvo tambien en las palmas creciendo bajo sombra de 80%, al final del experimento.
5-mm diameter) located on the leaf clip holder recorded the PPFD incident to the leaf during [F.

In summer our radiation as PPFD (photosynthetic photon flux density), may reach 2,200 [micro]mol photons/[m.
Selection for greater plasticity may be stronger in the gap species because gaps exhibit a relatively predictable decrease in PPFD for which plasticity could be adaptive.
