For the determination of leaf blade
intake (in % of BW), the mean flow of intake was multiplied by 100 and divided by the stocking rate.
"This grass has a thin leaf blade
and a slow rate of growth," Wolfin said.
Variation in true leaf area of (A) Psychotria carthagenensis and (B) Psychotria hoffmannseggiana, as a function of the product of leaf blade
length and width (LxW) using the models that were found to best estimate leaf area.
In relation to luminosity, it is possible to mention, among others, greater thicknesses of the leaf blade
and palisade parenchyma in leaves collected in the sun, which can increase the photosynthetic potential (EVERT, 2013; AMORIM; MELO JUNIOR, 2017).
Tiller number, stem diameter, leaf blade
width and leaf blade
length were also determined for plants in the first and second cuttings.
Be careful not to bruise the leaf blade
because damaged leaves will rot.
'BRS Energia' were determined at 80 DAS based on the percentage of cell membrane damage (%D), relative water content (RWC) in the leaf blade
, leaf succulence (SUC), plant height (PH), stem diameter (SD) and leaf area (LA).
This difference was attributed to the higher leaf blade
proportion during the trial period.
High GCV were recorded for fresh leaf weight (22.51), millable cane (22.28), bud size (24.02), and individual cane weight (37.79); while leaf blade
width (19.43), dried leaf weight (15.42), number of tillers (16.20), and cane diameter (17.58) showed medium GCV and leaf blade
length (4.45), chlorophyll content (5.39), number of internodes (5.00), internode length (8.55), plant height (7.14), stalk length (4.38), and brix% (7.05) exhibited low GCV.
Primary data were recorded on days to heading (DTH), days to maturity (DTM), plant height (PH), stem length (SL), peduncle length (PL), peduncle extrusion (PE), spike length (SpL), flag leaf auricle height (FLAH), flag leaf node height (FLNH), flag leaf sheath length (FLSL), flag leaf blade
length (FLBL), flag leaf blade
width (FLBW), productive tillers (PT), non-productive tillers (NPT), percent lodging (L), spike weight (SpW), grain yield per spike (GYPSp), grains per spike (GPSp), tiller vegetative mass (TVM), 1000 kernel weight (TKW), grain yield (GY) and biological yield (BY).
