Axonopus catharinesnis Valls. (gianty missionary grass) is a native forage species from Santa
Catarina State. This species is considered a good option to use in systems with tress because its
good tolerance to shade. When plants are growing under trees canopy, shade environment causes
changes in the quantity and quality of light, which can affect plants growth and development. The
aim was to evaluate the leaf morphogenesis and anatomical regulation of giant missionary grass
in function of alterations in light quality in a controlled environment. Three light conditions were
simulated in a growth room: low blue light level (B-), low red:far red light level (R-), and neutral
(N - control). Sodium vapor (400 w) and fluorescent lamps was used as light source and the light
conditions were obtained with a Lee filter HT 015, Lee 117 and Lee 216 for low blue, low red:far
red and neutral, respectively. The distance between plants and light sources plus filters was
adjusted in order to provide photon flux with the similar photosynthetic efficiency in B-
(Photosynthetic Active Radiation = 308 μmol m2 s-1), R- (PAR = 363 μmol m2 s-1) and N (PAR =
381 μmol m2 s-1). Twenty plants (i.e. replicates) from clones was grown individually in pots of 3,6
L at 25 ± 3ºC and 16 h photoperiod. Plants was watered with Hoagland plant nutrient solution.
Every 3 days, during 20 days, plant measurements was done to calculate the following parameters:
phyllochron (Phyl ? ºCd); leaf elongation rate (LER ? cm tiller-1 ºCd-1); duration of leaf elongation
(DLE - ºCd); leaf lifespan (LLS - ºCd); leaf blade senescence rate (LSR ? cm tiller-1 ºCd-1). At the
end of these measurements, tillers were collected to measure the specific leaf area (SLA).
Statistical analysis was performed using R software. There was no significant impact of light
quality on the parameters that affect leaf appearance and growth as Phyl, LER, DLE
(p.value>0.06). The R- reduced the LLS compared with the other light conditions (p. value 0.01),
while LSR was not affected (p-value 0.43). There was an increase of the SLA (p-value 0.001) for
B- (364.6 ± 28.5), R- (327.1 ± 18.7) while for N was 304.41 ± 40.4. These results demonstrates
that light quality has litlle effect on the leaf morphogenical parameters of giant missionary grass,
however there is an anatomical adjustment of the leaf due to the light quality alteration. This
process can interfere on the leaf forage quality, with a possible better quality of shaded
leaves. MenosAxonopus catharinesnis Valls. (gianty missionary grass) is a native forage species from Santa
